William Robertson on Historical Causation and Unintended Consequences (*)

Daniele Francesconi

1. A concern with causation characterized both the political thought and the historical writing of the Scottish Enlightenment (1). It implied that no theory of the social institutions or of the forms of government would be satisfying unless it provided a viable account of how they were brought about. As far as historiography was concerned, it meant that mere narrative would not be enough, and a collection of facts or a detailed account of events should be supplemented with a more "philosophical" critical outline of their causes.
In these circumstances, it is not surprising that the problem of causation loomed over the whole historical writing and thinking of William Robertson (2). When his biographer Dugald Stewart, speaking of the History of Charles V, remarked that Robertson had succeeded in tracing "a meridian [...] through the vast map of time", and in exhibiting to the mind "a line of reference [...] for marking the bearings of those subordinate occurrences, in the multiplicity of which its powers would have been lost", he was just referring to the explicatory powers of a causative reasoning, which brought clearness and a rational drift to the historical narration (3).
The aim of this paper is to try to reconstruct the role played by causative reasoning in the historiographical practice of Robertson. Rather than discussing his abstract method for classifying causes, I will therefore focus on a number of textual strategies whereby Robertson’s concern for an understanding of causes can be seen in its performative and operational aspect.
The rest of this paper is divided as follows. In the next section I will sketch out the various shapes taken by the languages of historical causation and unintended consequences in the historical writings of Robertson. In the two following sections, I will focus on one particularly remarkable instance of his theory of historical causation, and I will comment on the textual relationship between historical narrative and critical analysis of causes. Subsequently, I will turn to the presence of a language of the unintended consequences. This is a case in point of Robertson’s approach to historical causation. As the pattern of unintentionality underlying the course of history called for the exercise of special skills and the acquisition of unprecedented social knowledge on the part of the historian, I would also like to argue that the assessment of the causes of unpredicted effects was the main field for the display of a philosophical kind of history.
Lastly, in the final section I will draw some conclusions.

2. Robertson articulated his vocabulary of historical causation and unintended consequences in three main branches, namely those of Providential arguments, the stadial history of manners, and the political history of prudence and the public interest. It can be said that each of these languages presented a different set of causes. The Providential discourse was founded on the role the divine will supposedly played in the shaping of history. The history of manners was concerned with social and economic causes, or with historical factors we would now call cultural. Political history tended to explain history in terms of the dynamics and results of the struggle for power within the ruling élites.
These three different historiographical languages also framed alternative patterns of historical periodization. Providential history staged the intervention of God against a very long-term background, one would be tempted to say against an immemorial and eternal time. The history of manners adopted a long-term perspective. The confrontation between kingship and feudal aristocracy in Scotland, and the ultimate demise of the latter which coincided with the rise of the commercial age, for example, spanned more than two centuries in Robertson’s narrative, from the later Middle Ages to the British Union of 1707. Political history, on the contrary, focused on a middle-, and often a short-term chronological range, witnessed by the reign-by-reign arrangement of narrative, and by the annalistic device of constantly reminding the readers (top or side of the page) of the year in which the events narrated took place.
Let us briefly look at the ways in which Robertson conceptualised the problem of historical causation in each historical genre, beginning with Providential history.
The first appearance of a providential argument in Robertson’s writings occurred in a sermon on The Situation of the World at the Time of Christ’s Appearance that he gave to the Society for the Propagation of Christian Knowledge in Edinburgh in 1755. Although we should bear in mind that, given its different rhetorical nature, this sermon does not necessarily throw light on the role played by Providence in the historical writings, we can suppose that some of its conclusions had an influence on Robertson’s historical thought. He maintained here that only by the time the Roman Empire had come to conquer the Mediterranean world and to unite it in a single system of language, manners, and laws, the communicative conditions for the apostolic mission were created. He restated the providential connection between the birth of Christ and the consolidation of the empire under Augustus that had been established in the Patristic literature, by Eusebius, Origene and Augustine among others (4). Robertson showed a similar interest in connecting the providential Revelation of the Word to the political and commercial situation of the Roman world. The moral meaning of such a timing for the providential origin of Christianity was that the new religion could thus "check [...] the pernicious effects of despotic unlimited power" (5).

3. In both the History of Scotland and Charles V providential arguments are widely used, notably in the context of an account of the origins and progress of the Reformation (6). John Knox is called "the instrument of Providence for advancing the Reformation" (HS, II.35), and in front of such a revolution as the Reformation even "historians the least prone to credulity and superstition" can not but admit the operation of Providence (HC, II.78).
In accordance with a conception of Providence that was already very clear in the sermon of 1755, Robertson did not endorse a miracolous explanation of the progress of the Reformation. Robertson’s God did not intervene in the course of history as an absolute ruler, but acted as a constitutional monarch, refraining from changing the course of human events with His arbitrary lightning bolts, and delegating authority to the laws of nature and society, letting them handle everything. It was for this reason that Robertson dwelled instead on the political and cultural causes which brought about the sixteenth-century religious revolution (7). He referred to the grievances against the power of the clerics, the immorality of the clergy, the exorbitant wealth of the Church, the inalienability of the land usurped by the clergy, the benefits gained through the invention of printing, the revival of ancient political theory with its emphasis on civic liberty, as causes of the Reformation (HS, I.119-29, 156-57; HC, II.101-20, 205-06, 324-25, 337, 421-27). Robertson went as far as professing that he would not be concerned with the discussion of "Papist" theological doctrines because they belong to the domain of ecclesiastical historians; he would confine himself to the "influence of political causes" (HC, II.120). And the political dimension of the Reformation came to the fore when Robertson reconstructed the conflict between Charles V and the German princes, a struggle in which religious interests are always linked to the acquisition of power and to the reason of state.
The second language of historical causation to be found in Robertson’s writings is connected to what we may call a history of manners, and it frequently took the shape of a stadial conception of history. Like all the other exponents of the Scottish Enlightenment, Robertson was drawn to the concept of manners by the example of Voltaire, and he repeated the typically Scottish concern for a history of manners that was mainly related to the shifting settlements of property. In one of the end-text notes published in the section of "Proofs and Illustrations" to the View, Robertson proceeded to the reconstruction of four stages in the legal titles to ownership of the land: total independence, allodial property, feudal vassallatic and beneficial property and feudal hereditary property (View, 213-27). A stadial conception of society was often sketched out by the Scots (Robertson, who famously said in the History of America that "in every enquiry concerning the operations of men when united together in society, the first object of attention should be to their mode of subsistence" (HA, I.324), did not however stated explicitly a "four stages theory of history"). But it should always be borne in mind that no stadial history in the true sense of the word was ever fully developed in the Scottish Enlightenment. When, for want of a better word, I refer to a stadial history or a stadial conception of history, it should be understood that I mean less a sequential reconstruction of the history of society than a very powerful set of allusions to a certain mechanics of social and historical change (8).

4. It is fair to say that Robertson went an unprecedentedly long way in accommodating a history of manners within the boundaries of philosophical history (9). Robertson’s exercises in the history of manners are contained in the View (whose aim is said to be an account of two "revolutions in the manners of European nations. The first [...] occasioned by the progress of the Roman power; the second by the subversion of it", View, 1), in books IV and VII of the History of America (dealing respectively with the North American tribes and with the place of the Mexican and Peruvian empires in the scale of civilization), and in the Appendix to the Disquisition on the Knowledge that the Ancients had of India, which was composed first and subsequently postponed to the narrative account of European trade with India from antiquity to the rise of the Portoguese commercial empire.
The concept of manners came to have a very powerful influence on the whole question of historical causation (Hume once referred to manners as a "general cause" in history (10). We will see presently how the language of the unintended consequences as well hinged on the history of manners and property.
The third language of historical causation I will be dealing with, is embodied in a rather traditional understanding of the requirements of the narrative of political history. For the purposes of this paper, it is particularly important to point out that the narrative of political history was for Robertson strictly connected to an analysis of the motivations of historical characters (11). It shows yet another philosophical aspect of the historiography of Robertson, linked to a Tacitean representation of the hidden causes of human action (12). In framing a theory of historical characters and their motivations, Robertson faced a long-standing prejudice, according to which eye-witnesses only would be able to penetrate the meaning of the actions of historical actors. Dr. Johnson pointed out exactly this alledged limitation of Robertson’s point of view, when he remarked that "Robertson paints; but [...] you are sure he does not know the people whom he paints" (13). Not being an insider (as Tacitus, Guicciardini or Clarendon had all been), he would necessarily be unable to judge the actions of people he did not know.
By relying on a science of human nature, the Scots believed they could overcome that limitation. Since passions are tendentially uniform, the behaviour of the statesmen of the past could be reconstructed and judged accordingly. To be faithful and impartial, a historian needed not write contemporary history. Robertson felt he could penetrate the character of Charles V or Cardinal Ximenes with no less psychological and moral accuracy than Tacitus had shown in painting the mind of a Tiberius. This attitude helped to transform the traditional humanist language of the sinews of power into a more sophisticated picture of the interplay between ruling passions and considerations of the public interest. Although this language was not incompatible with the sentimental approach to history and with the morally exemplary character that civic humanism required of history, it would not have been possibile without the scientific anatomy of the passions set forth in the Humean science of human nature. An account of the motivations working behind the façade of human actions depended on an accurate definition and a precise differentiation between apparently undistinguishable similar passions.

5. In this paper I will mainly focus on the relationship between history of manners and political history in the writings of Robertson. As we have seen, although Providential history was for Robertson a distinct and autonomous genre of historical writing, when it came to questions of historical causation he often did nothing else than couch a secular account in a Providential language. It has accordingly seemed appropriate to leave Providence aside, and concentrate on manners and politics. Let me therefore briefly enumerate some of the differences between these two discourses.
The history of manners was about social groups and it focused on patterns of collective behaviour, while the humanist language of political history was predominantly concerned with the ruling passions of historical characters and their effects on public phenomena. Consequently, the history of manners (especially when it was expressed in a stadial language) dealt with structural changes, while the language of political history was mainly concerned with a process of decision-making. Moreover, while a history of manners was tendentially comparative and aiming at generalizations, political history was more évenementielle, and more strictly concerned with the particular and the unrepeatable.
Ultimately, history of manners and political history can be traced back to two alternative theories of passions. Self-love and the pursuit of private interest have an overriding importance in the history of manners, especially in its Scottish version, which was mainly concerned with the patterns of the acquisition of property, in a legal and materialistic sense. Mandeville’s remarks on the role of self-liking and emulation in the struggle for social power and wealth (14), Hume’s insights into the social function of pride (15), and Smith’s theory of the relationship between social vanity, self-improvement and the distinction of ranks (16), should however warn us not to forget that things were much more complex.
The humanist conception of passions underlying political history is founded on a much more elusive and heterogeneous set of passions and motivations. They may go from the pursuit of power to the acquisition of glory, from the fanatical search for religious conformity to the care for the welfare of one’s own subjects; they may be utterly selfless or narrowly egoistical. This complexity is one of the main reasons why it is extremely difficult to account for the patterns of historical causation and the language of the unintended consequences that can be found in the political history inherited by Robertson from the Renaissance.
These general differences between political history and the history of manners also account for the different types of arguments founded on the unintended consequences, that we find as we shift from one historical genre to the other. The language of the unintended consequences was deeply rooted in both genres. In the case of the history of manners, it tended to be concerned with the unexpected growth of public benefits out of the pursuit of private interest by the members of a social class (17). In the case of political history it took a different shape. The language of the unintended consequences was there embodied in a study of historical characters and the weight that motivations, passions and the fickleness and volatility of human behaviour might carry on public events and the pursuit of the public interest (18). Although the rationale of these two different applications of the idea of the unintended consequences could not be greater, in the historical writings of Robertson there was scope for their fruitful cooperation: they were therefore not contradictory, but complementary.

6. Robertson’s most elaborate treatment of historical causation is certainly the justly celebrated survey of the several causes of progress contained in the first section of the View of the Progress of Society in Europe. The View itself is a preliminary critical analysis preceding the historical narration of the reign of Charles V. It is a sweeping account of a number of transformations which occurred in the manners and political systems of medieval Europe. Because of its role as a conjectural history of the rise, progress and demise of the feudal system, Robertson did not consider it necessary to observe a "chronological accuracy", but chose to focus on the "mutual connection and dependance" between the different causes (View, 22). For its explicatory role the View can be compared to the preliminary study of the Scottish ancient constitution that Robertson put in the opening book of the History of Scotland. He believed that only after clearing the ground of any fable regarding mythical origins, and after providing a general framework of interpretation, could a traditional historical narration begin.
Robertson lists ten major causes or clusters of causes that brought about the rise of the European modern system of States after the fall of the Roman Empire. They are causes of different species — political, legal, commercial, cultural (interestingly, none of the causes mentioned by Robertson falls within the domain of the Providential conception of history). By so doing, Robertson wanted to convey the sense of the complexity and interdependence of the causes of civilization. Hume had been one of the first to realise it when he remarked that "we cannot reasonably expect, that a piece of woollen cloth will be wrought to perfection in a nation, which is ignorant of astronomy, or where ethics are neglected" (19).
Among the causes mentioned by Robertson, the forming of cities into communities, corporations, or bodies politic, the granting to them of municipal jurisdiction, and the acquisition by cities of civil liberty and political power were prominent. The rise to prominence by the cities was considered a fundamental step towards civlization by virtually all Enlightenment authors. Voltaire had emphasized much the same point in the Essai sur le mœurs, and Robertson will take the presence of cities as a crucial test on the degree of civilization of the Mexican and Peruvian empires (20).
Moreover, Robertson maintained that the Crusades had been a cause of progress because they had enlarged the views of the crusaders while they were travelling through many different countries and encountering different manners, and they had been a boosting factor for the progress of trade and commercial intercourse between peoples (21). We should note that in the case of the Crusades, as in that of the Reformation, Robertson put forward a mainly social and political, not theological and providential, framework of explanation. This is a confirmation of the prevailingly secular (although, on this issue, rather disturbingly imperialistic and ethnocentric) outlook of his historical thought.

7. Another cause of progress was the enfranchisement of farmers from the yoke of feudal dependency and the rise of a class of independent husbandsmen, a process which he had learnt to appreciate through Hume and Smith, and to which I will come back later in this paper.
This exercise in historical sociology on the causes of the rise of civil and commercial society was to become very influential in the British and European political thought and historiography of late-eighteenth and early-ninenteenth century. Although not much of it is original (Robertson is profoundly indebted to Montesquieu, Hume and Smith), it is fair to say that he succeeded in realising the most powerful and complete overview of the subject. It is the combination of acute insights and enjoyable narrative that gave the View the status of a classic it was to retain for a long time.
However we should also note that Robertson brought together a mishmash of different and sometimes incompatible sets of causes. He was aware of this, and warned that he was about to set forth "a succession of causes and events which contributed, some with a nearer and more conspicuous, others with a more remote and less perceptible influence, to abolish confusion and barbarism, and to introduce order, regularity, and refinement" (View, 21-22). Some of these causes are marked by an endogenous process of generation, like the enfranchisement of the cities and the abolition of feudal servitude. Others are characterised by a distinct external, and sometimes utterly accidental origin, like the revival in the knowledge and study of the Roman law, dependent on the accidental finding of a copy of Justinian’s Pandects in Amalfi in 1137. Some of them occur in the heartland of the European medieval civilization, while others (the Crusades, the progress of commerce) are linked to the attempts at commercial and military conquests pursued by some European medieval powers. Robertson emphasized the feedback between internal changes of the medieval world and the transformations brought about by events occurring on its boundaries. Moreover, the ten causes discussed by Robertson are located over a very long period of time. He is dealing with a process spanning the period from the "ultimate point of depression" at the beginning of the eleventh century (22) (View, 21) to the beneficial effects of the progress of commerce on the threshold of the discovery of America.
This picture of historical causes is also characterised by some internal flaws. For instance, Robertson put together the rise of the spirit of chivalry and the progress of commerce, although they are grounded on very different, and actually contrasting sets of passions (the former being founded on gallantry and altruism, while the latter is based on self-love and the pursuit of private interest), and they took place in very different historical moments. From this discussion is also absent the consolidation of monarchical sovereignty which is treated in the second section of the View, and which, according to Robertson, presided over the rise of the modern European system of States at the beginning of the sixteenth century. It is not clear whether Robertson considered this process as an effect of the ten causes discussed in the first section, or as an element to be ranked alongside them as a preparatory moment of the sociopolitical settlement of modern Europe.
Robertson’s aim in the first section of the View was to provide a description of the multifaceted and irreducibly complex character of historical causation. This is proved by the fact that he refrained from giving overriding importance to any cause, and was more concerned with emphasizing their "mutual connection and dependance". But how could one, on the basis of such a complex and multifarious framework, write a historical narrative that could be otherwise than untidy and rambling?

III

8. Two fundamental meanings of the eighteenth-century philosophical history emerge from the two species of historical discourse that Robertson placed beside pure narrative. The first is the history of manners and of the alterations of property of which I have already spoken. The second trend of philosophical history to be found in the writings of Robertson consists of the combination of the resources of the critical analysis of the sources with historical writing. Robertson used the textual scholarship to read documents critically and to place them in their intellectual and political context. Although he believed that this kind of research belonged "more properly to the province of the lawyer or antiquary than to that of the historian" (HC, I.xii-xiii), he was persuaded that a meticolous scrutiny of sources and the production of evidence from contemporary documents was what distinguished an "authentic history" from a merely "amusing tale" (HA, I.xv). Robertson was very keen on avoiding anachronism (View, 355) and on assessing every event and historical character, as he tried to do with Luther, "by the principles and maxims of their own age, not by those of another" (HC, II.67). Robertson therefore accommodated the three components of his historical writing (historical narration, remarks on the philosophical history of manners, and the provision of a critical apparatus) in special textual places. In his last historical work, the Disquisition on India, he was able to refer to his habit of keeping "historical narrative as much separated as possible from scientific and critical discussions" (DI, vi).

However, separating them did not mean sealing them off. It is true that Robertson was aware of the different purposes embodied by these different kinds of historical writing. The analysis of causes in the View, for example, could dispense with chronological accuracy because what Robertson aimed at there, was more a framework for periodization than a detailed reconstruction of a succession of events. It is not by chance that broad political and historical concepts as the "middle ages", the "Renaissance", or the "commercial age" were forged just in such a context. Yet, the articulation between the different components, if we consider his historical works on the whole, was very elaborate. The interpretative picture settled by the View, even if it was not explicitly picked or conjured up in the rest of the history of Charles V, was always present in the background, and certainly oriented the readers — something which Robertson certainly had predicted and wanted.
Hume had indicated the way for an integration of historical narration and representation of manners; but it was Robertson who got to the bottom of it. This is what Dugald Stewart meant when he said that Robertson had succeeded in blending "the lights of philosophy with the appropriate beauties of historical composition" (23).
What was at stake in Robertson’s writings was not simply a more advanced way of integrating and making compatible narrative history and history of manners. Since Voltaire, this had been only one aspect of the attempt to join narrative and philosophy. The fact is that philosophical history transformed narrative itself. While acknowledging that the History of Charles V was in many respects a conventional humanist history dealing with exploits of kings, war and diplomacy, Nicholas Phillipson has rightly pointed out that "nevertheless Robertson’s narrative was also penetrated with the historiographical categories of conjectural history" (24).
This is also apparent in the case of causative reasoning. In terms of historical composition, this problem can be defined as the dilemma of how to make analysis of consequences and consecutive order of narration coincide? Certainly, a broad and far-reaching analysis like that of the first section of the View could only be carried out by dispensing with chronology and replacing temporal succession with conceptual anatomy. Nevertheless in smaller-scale cases, notably in the treatment of the causes of the Reformation, both in the History of Scotland (I.119-29) and the History of Charles V (II.101-14), Robertson has been able to mix a critical discussion of causes and a chronological account of events.

9. I would now like to turn to the presence of a language of unintended consequences in the historical writings of Robertson.
It should be said at the outset that the issue of the unintended consequences can not be limited to historical writing, as it carries a wider significance, involving the meaning of Robertson’s whole activity, not only as a historian, but also as a Church leader, a University administrator and a public literary figure. The public and intellectual career of Robertson, as it has been reconstructed in a number of remarkable studies, was characterised by a firm faith in the role of human agency, and in the capacity of individuals to build a lasting consensus and a peaceful society. As a prominent member of the Moderate party within the Kirk, and as a University teacher (and eventually Principal of the University of Edinburgh) Robertson committed himself to steering a conciliatory course of action which would appeal to good sense. Together with his fellow-Moderates, Robertson believed that "there can be no Society, where there is no Subordination" (25). He stood for a civil liberty tempered by authority, and for a government that enforced discipline and order. In such a society there was room for religion as a civilizing factor. The mission of the minister of the Kirk was to lead and enlighten the people. The Moderates promoted an alliance between the clergy, the nobility and the gentry to promote the enforcement of the new patronage law, which according to Robertson would result in the selection of a superior type of minister. The Moderate ideology brought together the Christian teachings of morality with the Stoic encouragement to the "warmth of virtue" and the civic concerns for public virtue. Their main political aim was to create a moral and social consensus to the commercial society and the Hanoverian regime, and replace with it the private interest which was such a weak and shaky foundation of commercial society. In the political discourse of the Moderates the residual civic moralism of the Old Whig tradition was combined with the constitutionalism of Montesquieu in order to build what has been described as a Whig-Presbyterian conservative ideology (26).
The purpose of conciliation, dialogue and consensus was wrapped in a language of politeness (27). Indeed, in the policy of moral and rhetorical persuasion pursued by the Moderates in a number of sermons, addresses and historical writings, the etymological origin of politeness appears very clearly: their task was to rub and smooth off corners, to polish manners and sooth differences.
It is known that the ideology of the Moderates was reflected in Robertson’s historical discourse. The History of Scotland has been decribed as an attempt to conciliate the principles of the Enlightenment with the Presbyterian legacy, and to mark a middle ground between scepticism and enthusiasm (28). The activity of Robertson as a historian has been linked to the fashioning of an Anglo-British identity, that led the Scottish Whig historians to subvert the foundation of sixteenth- and seventeenth-century Scottish historical thinking (29). The moderate and conciliatory stance of Robertson’s political thinking has left an enduring mark on his very historical language. The core of his claim to impartiality lay in his dialogical integration of diverging positions into a single narrative (30). Narrative history was accordingly conceived by Robertson as a "means to conflict harmonisation" (31).

10. All these remarks lead to emphasize the confidence in human agency and the commitment to an authorial control over history. However, they do not mean that Robertson was not interested or did not believe in the explicatory power of the language of the unintended consequences. This is in part due to the fact that, by the time Robertson composed his works, the language of unintentionality had become a commonplace of Scottish historical discourse.
The role of this language in Robertson’s historical writings has recently been cast in doubt. According to Karen O’Brien, Robertson was "uneasy about the moral implications of the Scottish notion of unintended consequences in human affairs", because he believed that the kind of history in which that language was deployed accorded "too limited a place to the role of human intervention in history". Robertson opposed a conception of history as an "arena of moral choice", in which there would be scope for rational human agency, to a conception of history that emphasized the gap between the "natural course of things" and the power of human volition. O’Brien sees a profound difference between a narrative history, centered around the idea of moral and authorial responsibility, and a stadial history, founded on the materialist language of unlooked-for-by-products, and "always overshadowed by the Mandevillian spectre of morally nihilist satire" (32).
The Achilles’ heel of O’Brien’s interpretation is that her distinction between narrative and stadial history seems to be a little too rigid (at least as far as Robertson is concerned). Firstly, by so doing one would be in danger of collapsing the distinction between a stadial conception of society (often characterised by the progress from hunting to shepherding, from farming to commerce) and the principle of the unintended consequences in which that stadial process could be expressed. Although closely connected, they were by no means the same. Indeed there is evidence (Hume’s History of England being the most notable example) of the principle of the unintended consequences being lavishly used in works, which in other ways did not set forth a stadial interpretation of history. Secondly, it is arguable that both the principle of the unintended consequences and a stadial conception of history could be accommodated within the narrative body of a historical work.
An appeal to the unintended consequences, moreover, was not in itself a sign of Mandevillian moral nihilism. While retaining Mandeville’s evolutionary approach to the growth of social relationships, the Scots tried to "polish" his political thought. Hume and Smith faced Mandeville’s challenge and were at pains to show the legitimacy of private interests and the inherent contradiction that lay in calling "vice" a "public benefit" (33). By the time Robertson started his career as a historian, the core of the social theory of the Fable of the Bees had been taken on board in the much more sophisticated theory of justice and political economy of Hume and Smith, while the provocative "private vices, public benefits" program had been marginalized to the role of the brilliant, but vague formulation of a paradox: it seems fair to say that, although Mandeville remained a threat in the opinion of theologians and austere moralists, there was no Mandevillian ghost that could give sleepless nights to a serious and sophisticated political thinker like Robertson.

11. Certainly there could still be a rather sharp opposition between the didactic and pedagogical approach to moral philosophy endorsed by the Moderates and based on the Stoical teaching of Francis Hutcheson, and the analytical and scientific approach of Hume and Smith. But this did not mean that Robertson could not appeal to either of them, depending on what the circumstances suggested to be the best course of action. Eclecticism was the main characteristic of Robertson’s thought: he was no original thinker (in the words of Alexander Carlyle, he was "addicted to the translation of other people’s thought" (34), and he was quite willing to make use of any conceptual tool he found available to improve his work.
Adam Ferguson, another member of the Moderate literati of Edinburgh, managed to combine his whig and presbyterian ideology and his Stoico-christian providentialism with probably the most eloquent, and certainly the most famous, endorsement of the principle of the unintended consequences. And Adam Smith, although himself not a Moderate, did not find it strange to share most of their political and moral views even if he was the theorist of the invisible hand.
I am therefore persuaded that we can go in search of the application of the language of the unintended consequences in the historical writings of Robertson without necessarily postulating that its use put in jeopardy his moral and authorial commitment to moral virtue and political responsibility, nor that it had to be divorced from the narrative side of his histories (35).

V

As early as 1755, before the publication of his first historical work, the History of Scotland (1759), Robertson was already using to the language of the unintended consequences to explain the nature of the historical process. This occurred in the review of the History of Peter the Great Emperor of Russia, by Alexander Gordon of Auchintoul, published in the Edinburgh Review. In pure Voltairean fashion, Robertson remarked that "the attempt of Peter the Great towards civilizing that vast Empire, of which he was the Sovereign, is perhaps the most singular and interesting object that the history of mankind presents to the view of a Philosopher". Robertson was struck by the example (previously occurred only in the Greek city-states) of a ruler and lawgiver who could single-handedly set in motion a vast process of modernization and civilization. The size of his empire and the lack of any previous discipline in the people rendered the achievement of Peter the Great even greater than that of the archaic Greek lawgivers: "the Czar of Muscovy is the first man who, unenlightened by science, and uninstructed by example, conceived the vast design of civilizing sixteen millions of savages, and who, by operations the most amazing and adventrous, introduced armies and fleets, commerce and science, into an Empire where they were all unknown". The Czar was a "benefactor to mankind", much above the destructive character of a conqueror or the petty intrigues of an ambitious politician, and his actions would have deserved greater praise than the historians had so far accorded him. In the light of his grand achievement, even some negative features of his character ("the vices of the man, the violence of the tyrant, and even, on some occasions, the fierceness of the Barbarian") could be excused. Indeed, "perhaps even these defects contributed towards the success of his undertaking; and with less impetuosity, and greater gentleness of disposition, with more refinement, and a nicer sense of decorum, he might have left his grand enterprize at a farther distance from perfection" (36).

12. These considerations by Robertson confirm, in an Anglophone context, the exemplary character of the Russian experience for the eighteenth-century theory of civilization (37). Great men were no longer appreciated for their military exploit or for their conquering enteprises, but for their capacity to bring commerce, arts and sciences, and a more rational administration to their people. Underlying this view, there was an idea of civilization grounded on foundation of cities, economic reform, agricultural improvement, bureaucratic modernization — all the components of a leap forward from a backward to a modernized society. It is easy to understand why the Scots should be sympathetic to such an agenda of improvement, and Robertson’s remarks are in tune with the contemporary French debate (38).
Interestingly, Robertson is here already moving away from the idea of the civilizing achievement of a sovereign towards the concept of the evolutionary progress of the society, made possible by the concurrence of favourable historical circumstances. This is why it is difficult to determine whether Robertson is here speaking the language of political history, or of the history of manners? At first sight, the achievements of Peter the Great may belong to political history (or perhaps, we may say, to political myth). Here we have an absolute ruler who sets out to reform the institutions of his State and to improve the society over which he lords. The figure of Peter towers over the historical scene, and it is his sovereign will which alone can dramatically change the circumstances of his people.
But some key-words of the history of manners and of a stadial conception of society appear in Robertson’s text. Peter is not simply giving laws to his subjects, but also undertaking a "design of civilizing" his people. They, in their turn, are called by Robertson "sixteen millions of savages". Russia must be in a savage state as no firm right to private property is established there.
Is Peter a lawgiver, or a civilizer who helped a society move from one historical stage to the next? How much of his achevement hinged on the stadial circumstances of pre-modern Russia? If we focus on the picture of the history of manners Robertson is giving us, the achievement of Peter may not seem as striking as it appeared. In the context of a savage or barbarous society, the revolutionary success of a single individual gifted with power and charisma is not exceptional, indeed it is almost predictable (39).
The ambivalence of this historical example is strengthened by the idea of Robertson, according to which Peter the Great is an exceptional type of ruler, a virtually unique example, at least within the modern age. The development of civilization is in fact usually embodied in a process of unintended consequences: "commerce, learning, the art of war and polished manners, have penetrated into most nations by degrees, and have owed their establishment more to the casual operation of undesigned events, than to the regular execution of any concerted plan" (40). The ambiguity of Robertson’s judgment on the achievements of the Czar is an early proof of the complex relationship between sovereign will and the unintended progress of society. We will presently see other examples of it.
Some years before the publication of his first historical work, Robertson was therefore already subscribing to the language of anticontractarianism and unintended consequences which he may have learnt to appreciate while attending the lectures on jurisprudence that Adam Smith delivered in Edinburgh in 1748-50 (41). It is also already clear that, even at such an early stage, Robertson was moving away from the historical discourse in which he had been trained by Charles Mackie: the theme of the unintended consequences does not seem to be prominent in the courses that Mackie did in the University of Edinburgh (42).

13. The History of Scotland, Robertson’s first major work, was not shaped by this stadial and conjectural language. It is best described as a political history whose main purpose was ideological, as Robertson rejected the Buchananite aristocratic ideology and set forth a modern Whig account of the constitution. Similarly, he substituted a philosophical and moderate account of the Scottish Reformation for the more traditional, again Buchananite, Presbyterian approach (43).
Although the language of the unintended consequences is alien to this context, it makes an appearance in the History of Scotland. And although it is not an explicit statement, and is relegated to a passing remark, it indicates revealing similarities. Opening up a comparative perspective on the state of England at the middle of the sixteenth century, Robertson commented on the policy of Henry VIII and remarked that "the vices of this Prince were more beneficial to mankind, than the virtues of others. His rapaciousness, his profusion, and even his tyranny, by depressing the ancient nobility, and by adding new property and power to the Commons, laid the foundation of the British liberty" (HS, I.98-99). Robertson was here implicitly comparing the successful attempt to abolish the feudal servitude carried out by the English kings, with the resilience of baronial power in the Scottish constitution. Robertson gave several reasons why the balance of power in Scotland still inclined to the side of the nobles (HS, I.19-37). Although he believed that the power of the aristocracy was to a certain extent beneficial to the people, as it put in place principles which "tended to their security and advantage" and prevented any "act of arbitrary power" (44) (HS, II.249-50), it also clearly meant that Scotland would not be able to set out on a course of improvement and modernity (45). The rise of civil liberty which elsewhere had been helped by strong and centralised monarchies, in Scotland, because of the weakness of the sovereigns and the power of the factious barons, could only be brought about by the Union of 1707 and the commercial progress which finally destroyed the privileges and the political authority of the feudal nobles (HS, II.253-54).
The story had been different in England, where the struggle between the feudal lords and the sovereigns was fought and won by the latter in the second half of the sixteenth century. However, the rise of the Commons and the establishment of civil liberty that followed the demise of the feudal property were an unintended consequence of the kingly policy. In the History of Scotland, as we have seen, Robertson spoke (in unmistakably Mandevillian and Humean terms) of benefits to mankind generated by the vices of Henry VIII. In Charles V, he enlarged his comments on the topic, this time bringing more clearly to the fore the unintentional character of the effects of Tudor policy: "Henry VIII, probably without intention, and certainly wthout any consistent plan, of which his nature was incapable, pursued the scheme of depressing the nobility, which the policy of his father Henry VII had begun" (HC, III.440-41).
Robertson is referring to a familiar account of the gradual increase in the power of the Commons which was related to a monarchical policy of centralisation of sovereignty and of fragmentation of feudal property. This transformation occurred in three phases. In the late Middle Ages the monarchy favoured the creation of a new nobility, more loyal to the sovereigns. Henry VII’s legislation against nobiliar rents was a further destabilizing factor for baronial power (View, 101-03). Finally, by making available a large quantity of land, Henry VIII’s dissolution of the monasteries produced the conditions for the rise of a new class of owners.


14. The Scots all emphasized that the establishment of civil liberty and the rise of the Commons were unintended consequences of the Tudors’ policy (46). In the same year as Robertson published his seminal insights on the matter in the History of Scotland, Hume dealt with the problem in a very similar way in the History of the House of Tudor. Interestingly, Robertson proved himself even more radical than Hume on the question of the role played by intention in the process. Hume had saved some ground for the intentional action of Henry VII, and said that he probably "foresaw and intended this consequence, because the constant scheme of his policy consisted in depressing the great, and exalting churchmen, lawyers, and men of new families, who were more dependant on him" (47). Robertson, on the other hand, both in the History of Scotland and in his subsequent treatment of the subject in Charles V, did not seem to be prepared to concede it to Henry VII and Henry VIII. It was not through enlightened self-interest that Henry VIII accomplished the depression of the nobility, but through the unpredicted outcome of his blind rapaciousness and tyrannical aspirations.
The demise of feudalism brought about by the early Tudors policy is a textbook-case of a stadial conception of history at work. But it also raises a question, that is rarely asked by the historians but is nonetheless crucial: if they did not intend to promote the rise of the Commons and the establishment of civil liberty while they relentlessly pursued the "depression of nobility", what then were the early Tudors up to? They must have had expectations, and Robertson refers to it when he remarks that, although there was not any "consistent plan", Henry VIII pursued a "scheme" first undertaken by his father. We are here clearly in a context of political history, grounded on the politics of kingly ambition and the pursuit of glory, and on the language of the reason of State and the acquisition of power. Without such resort to political history, Robertson would not have been able to account for the motives underlying a pattern of behaviour with the most far-reaching consequences. Political history could not be dispensed with, if the early-modern revolution in the manners was to be understandable.

VII

The View of the Progress of Society in Europe (1769) spectacularly displayed the explicative powers of conjectural and stadial history. It compensated for its lack of originality with a wide range of topics, a finely balanced textual arrangement, and an unprecedentedly elaborate scholarly apparatus of "proofs and illustrations". It dealt with a large-scale transition from a feudal to a commercial society, spanning several centuries and encompassing the whole of Europe (with brief incursions in the Middle East and Turkey), and was an appropriate place to show the resources of the language of the unintended consequences. The View was one of the first texts in which the recently forged stadial theory could be displaced onto the actual historical ground.
It has been recently argued that "what is missing from ‘A View’, as a piece of Scottish stadial history, is any sense that the post-feudal sixteenth century is the unlooked-for-by-product of medieval man’s individual appetites and drives" (48). This would be due to the fact that Robertson, in describing the waning of the Middle Ages, adopted a distinctively Voltairrean tone and attempted to save the intentional action of social groups in the growth of modern society. As I have already said, however, the adoption of a moral stance does not seem to be a reason sufficient enough to discard the use of the language of the unintended consequences: this latter was morally neutral, and could be combined with the most different attitudes to the growth and feasibility of modern society, as the examples of Mandeville and Rousseau, Hume and Ferguson make clear.

15. The View reveals a profound sensitivity to the issue of the unintended consequences. When Robertson overviews the total change undergone by Europe around the end of the sixth century and the establishment of the barbarous states which would subsequently give rise to the feudal system, he remarks that it is "in the obscurity of the chaos occasioned by this general wreck of nations" that "we must search for the seeds of order, and endeavour to discover the first rudiments of the policy and laws now established in Europe" (View, 11). Furthermore, while introducing his multi-layered causal analysis of the growth of social order and regular government, he speaks of causes "with a nearer and more conspicuous, others with a more remote and less perceptible influence" (View, 21). Throughout the text of the first section of the View phrases referring to the unpredicted character of the historical process proliferate. Robertson speaks of the "beneficial consequences" of the Crusades, "which had neither been foreseen nor expected" (View, 25-30). He observed that laws, subordination and polished manners, after growing in the cities, "diffused themselves insensibly through the rest of society" (View, 36) (49). And he acknowledged the "imperceptible progress of juster sentiments concerning government, order, and public security" (View, 47).

VIII

The unintended consequences do not explain the whole of the View of the Progress of Society in Europe, let alone the ensuing narrative of the reign of Charles V.
In the View Robertson emphasized the role played by the cooperation between sovereigns and municipalities in bringing feudalism to an end (50). He focused on the intentional and purposive action of collective and institutional groups, in a way reminiscent of Ferguson’s method and qualifying the issue of the unintended character of their actions. Absolutist and centralized monarchies played a pivotal role in this process. The second section of the View was accordingly devoted to chartering the progress of monarchical power in the fifteenth century (View, 83-121). The French sovereigns, strengthened by the acquisition of the Continental territories previously in the hands of the English and by the heavy losses suffered by the French nobility during the wars with England, started the process of consolidation. The policy of Charles VII and Louis XI was crucial in this transition. The submission of the feudal nobility and the consolidation of monarchical power spread rapidly to England, Spain, the Habsburg German empire and the Ottoman Empire. Before the establishment of parliamentary assemblies to counterbalance the power of the sovereigns, monarchical authority was unlimited to an unprecedented degree; the institution of standing armies liberated the sovereigns from their dependence on their baronial allies, and helped improve the technology of warfare; higher taxation and an increase in public revenues gave the monarchs the economic basis of power that they needed to feed an increasingly centralized administration of the State and their armies. The new military and economic power made possibile for the monarchs to engage in wars of conquests (which were utterly impossibile for the feeble and factious feudal armies), and this was only one of the factors that brought about a new European balance of power in the shape of a system of increasingly interdependent national States.

16. Robertson was here covering a territory which had already been charted, although from a different perspective, by Francesco Guicciardini. There are some striking general analogies between Robertson’s treatment of this issue in the History of Charles V and Guicciardini’s approach in the Storia d’Italia. Guicciardini came to realize that the causes of the early sixteenth-century Italian political crisis and of the failure of the political project of the ottimati could not be understood from the narrow point of view of city-state politics. Italian politics ought to be included in a much broader political context, as Italy had become the battlefield for a conflict between new territorial monarchies. The rise of new political entities such as the French and the Habsburg monarchies called for the adoption of a new political thought and of a new historiography: the Peninsula must be the new object of historical narrative, not out of national conscience, but because it is the theatre of the new European politics of the balance of power.
On all of this Robertson thoroughly agreed with, and can be regarded as a follower of, Guicciardini, whom he called "the most sagacious, perhaps, of all modern historians" (View, 132) (51). But, with the hindsight he enjoyed from his eighteenth-century vantage-point, Robertson added a broader periodization based on the history of manners, whereby he was more able to account for the transformation in monarchical power at the turn of the fifteenth century.
The second section of the View of the Progress of Society in Europe is therefore part and parcel of the history of the reign of Charles V. The narrative volumes would otherwise be unintelligible, or we would not be able to account for the transformation Robertson brought to the framework of humanist history (52). The history of manners shapes political history. Moreover, it helps bring to the fore an underlying language of the unintended consequences.
For all his emphasis on the willing actions of the monarchs, it is not clear whether Robertson conceived the growth of the European modern balance of power as an intentional and predictable outcome of their policy. Some clues seem to indicate that this was not the case. Robertson attributed to the sovereigns of this period a lack of strategic understanding of the requirements of the new system of the balance of power. He explained it with the transitional character of late fifteenth- and sixteenth-century history, the time when a "monarchical moment" paved the way to a more stable, and to Robertson more familiar international political system. The gradualism implicit in a history of transitions is by no means equivalent to the acknowledgment of the appearance of unintended consequences. However, it suggests the lack of rationally constructed courses of actions and leaves open the door to an unintentional reconstruction of the rise of modern political institutions.
This consideration is strengthened if we look at the set of motivations which Robertson attributed to Charles V, which he took as highly representative of the conduct of absolute monarchs in the transitional phase of European history.
Charles may not have undertaken the creation of a universal monarchy (53), but he was driven by an insatiable ambition of conquest and "his desire of being distinguished as a conqueror involved him in continual wars, which exhausted and oppressed his subjects, and left him little leisure for giving attention to the interior police and improvement of his kingdoms, the great objects of every Prince who makes the happiness of his people the end of his government" (HC, III.419). Charles always acted for wholly secular and political considerations (as becomes an emperor), and despite the "specious veil of religion" under which he usually covered the real motives of his actions, he seemed "but little under the influence of religious considerations" (HC, II.298).

17. In the case of Charles V, we are facing a historical player whose actions are motivated by a rather narrow-minded and self-centered interest (which did not take into account the welfare of his subjects), which however helped promote the shaping of an European political system which, according to Robertson, would ultimately spread benefits and advantages for all. But, on the textual evidence provided by Robertson, one would find it difficult to argue that the promotion of civilization was intended by the likes of Charles V.

IX

The History of America was quite literally founded on an unintended consequence. Being the result of a mere mistake and of a fanciful and inaccurate prediction, the discovery of America was neither expected nor intended by the Genoese navigator who thought he would reach India by sailing westward and open a new and more profitable commercial route. In this epoch-making event all the components of the historiographical language of unintentionality were stretched: the discovery of America was the product of chance and depended in its turn on the "fortunate discovery" (HA, I.35) that led to the invention of the compass; it was an achievement that went beyond (and actually contradicted) the intentional aims of Columbus; it provoked a conquest and colonization which ultimately, according to Robertson, had beneficial consequences despite the self-serving interests that caused them.
The lack of predictability was, at an even deeper level, a typical characteristic of the encounter between two alien cultures. The radically unprecedented situation in which the conquerors and their Amerindian counterparts found themselves compelled Robertson to revise some of his beliefs about what was worth being related in history. He showed how such a socially marginal character as doña Marina, the native who became Cortes’ interpreter, could play a crucial role in the events that led to the conquest of the Mexican empire; the lesson that Robertson drew from this episode was that in the history of the New World, "great revolutions were brought about by small causes and inconsiderable instruments" (HA, II.12). Historical actors were players in a context which it was dangerous to compare with anything familiar in European history, and this meant that the historian should be more vigilant than ever of the historical power of unintentionality (54).
The principle of the unintended consequences is endorsed in the History of America in a way which at first sight is reminiscent of Mandeville’s argument. Let us consider the motivations that underlay the expeditions of the Spanish adventurers in the New World. In both the cases of Cortes and Pizarro, Robertson maintained that they amounted to a mix of religious enthusiasm and spirit of adventure united with avarice (HA, II.10, 150). Once they established the first contact with the natives and received the gifts of cotton, gold, and silver, the sight of such opulence, "instead of satisfying, increased the avidity of the Spaniards" (HA, II.14). The conquerors were Mandevillian individuals driven by irrational appetites such as vanity and the desire to hoard precious metals. Thier delusive ideas were grounded on the mistaken mercantilist principles which equated wealth with gold. Robertson attempted to distinguish between the "rude conquerors of America", whose superstitious pursuit of gold had led them to neglect the long-term consequences of their actions, and the Spanish monarchy which set up colonial institutions intended to advance her wealth and glory (HA, II.226).

18. But the Spanish colonial empire was founded on a mistaken principle of political economy. Following Smith, Robertson devoted book VIII of the History of America to a critique of the mercantilist principles which regulated the politics of the Spanish colonies (55). Instead of putting in place policies which favoured agriculture, commerce and trade, the Spanish colonies were established for the extraction of gold and silver, a decision which guaranteed short-term prosperity to the Spanish mother-country, but did not achieve lasting and long-term beneficial consequences (HA, II.387-88, 391-92). On the contrary, it unleashed an inflationary trend which ultimately would destroy the power of Spain. When in the 1760s Charles III’s minister, Campomanes, masterminded a reform of the colonial system inspired by the economic discourse of free-trade, it was too late and Spain had long become a marginal player in the European balance of power (HA, II.414-34).
The "private vices" of the conquistadores and the self-serving policy of the Spanish crown did not usher, in the American case, any "public benefit". Robertson severely criticized the Spanish colonial empire from a free-trade and humanitarian point of view, for its utter destruction of two ancient and worthy civilizations, the inhumane treatment of the American Indians and the slaves, the superstitious program of forced mass-conversions, the errors of economic policy, and the maladministration of the colonies.
However, he was aware that America was important in the creation of an international commercial system, and in the Disquisition of India he put the issue in a more global context: he contended there that the coincidence of the discovery of America and the opening of a new route to the Indies through the Cape of Good Hope was a "singular circumstance" worthy of observation, as, without the gold and silver of the American mines, the European nations would not have been able to afford the increase in the consumption of luxuries from India which the easier communication now made possible (DI, 209-11). Although Robertson did not say it in so many words, the first world system of commerce clearly appeared to him as an unintended consequence of quite distinct and competitive enterprises.

In Robertson’s works the history of manners did not replace, but rather completed political history. One might say that the history of manners generated and at the same time regenerated political history. The history of manners generated political history, because when the insights of the stadial conception are displaced onto the actual historical ground, the problem of power and sovereignty is also raised. We have seen that the change of manners promoted and exploited by the first Tudors or by Charles V would not have been comprehensible without a framework of political history.
But political history was regenerated by the history of manners, as the latter set political events and processes in a broader periodization scale, took into account a wider range of causes, and showed the close link between government and manners.
As I have tried to show in this paper, the language of the unintended consequences featured prominently both in the history of manners and political history. This theme has been probably too much neglected in the recent scholarship on the political and philosophical histories of the Scottish Enlightenment (56). I believe that the writings of William Robertson are a case in point for the pervasive presence of such a language.
Robertson’s whole ability as a historian, his capacity for sweeping and wide-ranging accounts of the rise and fall of civilizations and empires, his acute awareness of the relevance of small details and paradoxical outcomes for the writing of history, could not be explained if we did not appreciate the importance of the language of the unintended consequences for his historical thought.

6 Robertson’s belief in the workings of Providence earned him the criticism of Hume, who complained about the "Godly Strain" of the History of Scotland: Hume to Hugh Blair (25 Mar. 1766), in The Letters of David Hume, 2 voll., edited by J.Y.T. Greig (Oxford, 1934), vol. II, 31. In a letter to Robertson (Feb. or Mar. 1759), Hume wrote that a reader of the Tudor volumes of his History of England would have had "the pleasure of seeing John Knox and the Reformers made very ridicolous": Letters of Hume, vol. I, 300.

7 It has been maintained, although in a not entirely persuasive way, that Robertson’s interpretation of the Reformation should be linked to a Knoxian tradition: see M. Fearnley-Sander, "Philosophical history and the Scottish Reformation: William Robertson and the Knoxian tradition", Historical Journal, 33, (1990): 323-38. The limit of this interpretation is that the prophetic-apocalyptic dimension of Knoxian political thought is absent from Robertson’s moderate discourse. Robertson’s appeal to Providence is more aptly traced back to the inspiration of the Arminian theology and to the sinergy between human and divine will: see J. Smitten, "The Shaping of Moderation: William Robertson and Arminianism", Studies in Eighteenth-Century Culture, 22, (1992): 281-300. More recently Nicholas Phillipson has shown in a remarkable essay the pivotal role played by a re-defined natural theology in the development of Robertson's historical writing: N. Phillipson, "Providence and progress: an introduction to the historical thought of William Robertson", in William Robertson and the Expansion of Empire, edited by S. Brown (Cambridge, 1997), 55-73.

Earlier, Boswell had praised Robertson, "in whose History we find such penetration — such painting". But Johnson had replied that Robertson "draws from fancy", so much so that one "must look upon Robertson’s work as romance". Johnson went as far as saying that he preferred Goldsmith’s Roman History to the "verbiage of Robertson" (see vol. II, 237). This must be one of the greatest blunders that Dr. Johnson has ever made.

17 It should be remembered that Providential history has been often considered as a precedent of several eighteenth-century endorsements of the principle of the unintended consequences. This is the case of the social thought that eventually resulted in Mandeville’s theory of "private vices, public benefits" and in Smith’s invisible hand, on which see J. Viner, The Role of Providence in the Social Order (Philadelphia, 1972). Eighteenth-century historical thought has also been said to amount to a secularization of the providential theology of history, and Vico’s unintentional provvidenza legislatrice can be said to share some of the features Robertson later ascribed to Providence; see: K. Löwith, Meaning in History (Oxford, 1949) and A. Funkenstein, Theology and the Scientific Imagination (Princeton, 1986), 202-89.

18 David Allan has argued that the Scottish debate on unintended consequences had Calvinist and Stoic roots: see his Virtue, Learning and the Scottish Enlightenment.

35 The presence of a "principle of the heterogeneity of ends" is discussed in P. Moore, The Nature of Theoretical History and Its Applications in the Works of William Robertson, Unpublished Ph.D Dissertation, University of Edinburgh, 1975, especially 36-77. But, as she has focused on the "theoretical history" (a label invented by Dugald Stewart and perhaps not wholly appropriate in the case of Robertson), she has not grasped the importance of the unintended consequences for historical narrative.

37 For what follows I rely on the conceptual framework developed by Gianluigi Goggi in his "Diderot et le concept de civilisation", Dix-huitième siècle, 29 (1997): 353-73. For an earlier sketch of his model, see G. Goggi, Le mot civilisation et ses domains d’applications, 1757-1770, Studies on Voltaire and the Eighteenth Century, 346 (1996): 363-67.

38 In 1755 Voltaire’s Histoire de l’empire de Russie sous Pierre le Grand had not yet been published (it appeared in 1760 with the date of 1759). But of course the contrast between the delusive and short-lived dreams of conquest of Charles XII of Sweden and the rational and lasting civilizing project of Peter the Great had already been pictured by Voltaire in his Histoire de Charles XII, roi de Suède (1731): see Voltaire, Œuvres historiques, edited by R. Pomeau (Paris, 1957), 68-77 (much of this text was added in 1739), 125-26, 161-62; and compare F. Diaz, Voltaire storico (Turin, 1958), 89-93. It is not known whether Robertson read the history of Charles XII?

39 On the authority of the chiefs in a pastoral society, see: A. Smith, Lectures on Jurisprudence, edited by R. L. Meek, D. D. Raphael and P. G. Stein (Oxford, 1978), LJ (A), IV.1-58; J. Millar, The Origin of the Distinction of Ranks (1771), edited by J. V. Price (Bristol, 1990), 140-75.

Forbes, "‘Scientific Whiggism’: Adam Smith and John Millar", Cambridge Journal, 7 (1954): 643-70, especially 644-45.

42 Mackie however seems to have been interested in questions of historical causation. He defined the causarum et eventum collatio as one of the aims of history. Moreover, he once distinguished two kinds of universal history: the first consisting in a simple narration ab origine mundi, the second in a discussion of "causas [...] et alias ut hodie vocant circumstantias", after the example of the particularis historia: see C. Mackie, Lectures and Papers, 1719-1753, Edinburgh University Library, MS La.II.37, ff. 63r and 90v respectively.

49 The "silent or insensible revolution" in the manners, a phrase used also by Hume, was a key-word in the eighteenth-century language of the unintended consequences.

50 The chapter on Robertson in G. Falco, La polemica sul Medio Evo (1933), new edition edited by F. Tessitore (Naples, 1974), 155-90, remains a very good treatment of this whole process.

51 Unsurprisingly, Robertson relied heavily on Guicciardini in CharlesV. Guicciardini’s name is one of the most recurrent in the footnotes to the narrative volumes of that work. However, this did not hinder Robertson from disagreeing with Guicciardini on some factual points, as in the case of the account of the publication of the Indulgences.

52 Robertson’s debt to the Renaissance historiography was so great that untrained readers could mistake his history of Charles V for a traditional political biography; this happened to monsignor Caetani, writing to Robertson from Rome (10 December 1779), who simply referred to Robertson’s "vita di Carlo V": Robertson-MacDonald Papers, National Library of Scotland, MS 3943, f. 109r.

53 On the eighteenth-century language and critique of universal monarchy, see J. Robertson: "Universal monarchy and the liberties of Europe: David Hume's critique of an English Whig doctrine", in Political Discourse in Early Modern Britain, edited by N. Phillipson and Q. Skinner (Cambridge, 1993), 349-73; "Gibbon's Roman Empire as a universal monarchy: the Decline and Fall and the imperial idea in early modern Europe", in Edward Gibbon and Empire, edited by R. McKitterick and R. Quinault (Cambridge, 1996), 247-70.

Armitage, "The New World and British historical thought: from Richard Hakluyt to William Robertson", in America in European Consciousness 1493-1750, edited by K. O. Kupperman (Chapel Hill, N.C., 1995), 52-75. On his method in the History of America, see M. Duckworth, "An eighteenth-century questionnaire: William Robertson on the Indians", Eighteenth-Century Life, 11 (1987): 36-49.

55 "None of your friends [...] will profit more by your labours than I. Many of your observations concerning the Colonies are of capital importance to me. I shall often follow you as my Guide and instructor", William Robertson to Adam Smith (8 Apr. 1776), in The Correspondence of Adam Smith, revised edition, edited by E. C. Mossner and I. S. Ross (Oxford, 1987), 192. On the eighteenth-century transformations of the language of empire see A. Pagden, Lords of All the World. Ideologies of Empire in Spain, Britain and France, c. 1500- c. 1800 (New Haven and London, 1995), chaps. 5-7.

56 R. Hamowy, The Scottish Enlightenment and the Theory of Spontaneous Order (Carbondale and Edwardsville, 1987) is a notable exception. But unfortunately Hamowy has limited himself to an orthodox Hayekian definition of the principle of the unintended consequences and to an exploration of its relevance to the Scottish social theory and political economy. By so doing, he has failed to appreciate the wider implication and intellectual context of the language of the unintended consequences and its deeply rooted presence in historiography.
