that despite the wide variety of behaviour we find in different cultures, there is a shared basic model of human psychology. This means that no one form of social life is any more ‘natural’ than any other, and so crude ethnocentric judgements are to be avoided. The point is not that some societies are defective or corrupted according to some crude normative scale, but rather that they need to be understood in their own terms. The commitment to a universal human nature has several further implications for Smith’s thinking. Smith, unlike some of his fellow Scots, is uninterested in ideas of race or polygenesis: all human beings are the same in his view. More generally, the thinkers of the Scottish Enlightenment also had to defend the idea of a universal human nature from the possibility that human behaviour was directly affected by the physical environment. In the Spirit of the Laws, Montesquieu had detailed experiments with heat and cold that purported to show that the climate had a direct effect on human physical responsiveness. This could then be used to explain why different parts of the globe displayed different behaviour. David Hume, in the essay ‘Of National Characters’, systematically destroyed this theory and demonstrated that differences in behaviour between different social groups are due to social factors rather than differences in climate. The differences between the French and the Germans cannot be explained by radically different climates, nor do geographically dispersed people such as the Jews differ radically in the practices they maintain.
Second, the descriptive account of different types of society need not be understood as deterministic and inevitable. Smith is not saying that all societies will inevitably pass through the four stages. Indeed, he is explicit that there are examples of mixed forms of society, of societies that have moved from hunting to agriculture without being shepherds, and even that there are societies that have been commercial and are now agricultural. Lived history does not fit neatly onto the model being developed here, but that does not diminish the accession of knowledge that the science of man acquires by thinking about societies in this way. Even if we had a complete historical record of a particular society’s development through time, and that record did not conform to the conjectural speculations, this would in no way discredit the approach. As Dugald Stewart observed, the systematic knowledge advances our understanding of the general phenomenon of society as such.
Social Change
In addition to being an academic enterprise, the development of conjectural history was intended to provide an account of how social change might have occurred that was more closely related to the available evidence than that of the contract theorists. Smith and his fellow Scots were not the first to attempt something like this, and it is worth pausing to consider the impact of two such influential accounts as they help to set the scene for Smith’s own moral philosophy. Among Smith’s first published works was a letter to the Edinburgh Review (1756) where he discusses contemporary philosophy, the Encyclopédie, and Jean-Jacques Rousseau’s (1712–78) Discourse on the Origin and the Foundations of Inequality among Men (1755).46 In it Smith compares Rousseau to Bernard Mandeville (1670–1733), the author of the controversial Fable of the Bees, and situates him in the context of a debate about the possibility of virtuous self-interest and its tension with the idea of socially directed morality.
Rousseau had adopted a deliberately contrarian attitude to the Enlightenment notions of reason, science, and progress. In his Discourse and elsewhere, he made the case that the development of modern civilization was not an example of progress but rather a tale of the corruption of humanity from an original innocence to a selfish and vanity-driven modernity. Rousseau’s account dwelt on the idea that the process of socialization had created perverted value systems grounded in envy and self-conceit, where pride and concern for social status had transformed humanity for the worse. As Smith rightly noted, Rousseau’s idea was very similar to that of Mandeville, who had extended his original satirical poem about a beehive, which charted the beneficial unintended consequences of selfish behaviour (burglars make work for locksmiths), into a theory of morality that reduced moral behaviour to a desire for social approbation and an aversion to social embarrassment (the moral virtues are flattery begot on pride). Mandeville’s conclusion that private vices created public benefits signals an issue that clearly came to fascinate Smith: what happens when intentions and outcomes do not obviously cohere?
These ideas are interesting because they provide us with the initial jumping-off point of the Moral Sentiments. Rousseau and Mandeville had focused on how a set of shared beliefs and institutions could emerge from social interaction: for Rousseau, the result was a moral abomination and a deeply corrupted society; for Mandeville, the result was the cynical realization of the unintended generation of wealth and power. Smith had before him a mode of explanation that promised to allow a scientific, evolutionary, and naturalistic account of how human moral practice emerged as an unintended consequence of social life, but he also had before him two quite different conclusions about whether this was necessarily a good thing.
It is clear that Smith had been thinking about the relationship between self-regarding and other-regarding behaviour for quite some time. His teacher, Francis Hutcheson, devoted considerable energy to attacking Mandeville’s theory and developed his own account of a unique mental faculty, a moral sense, that discerned moral truth in the same way that sight and hearing discern external stimuli. Hutcheson believed that the characteristic principle of our moral sense was benevolence, and so Mandeville’s account of the generation of morality was back to front. Hutcheson was contributing to a debate within a particular strain of British moral philosophy. This strain held that morality was best understood as an emotional experience rather than a rational experience. Thinkers such as Lord Shaftesbury who stressed benevolence and self-command might have differed greatly from those like Thomas Hobbes (1588–1679) who stressed passion and self-interest, but they all operated on the assumption that it was feelings, passions, and emotions that moved human beings. The challenge for these moralists was to come up with a way to reconcile the fact that individuals were moved by feelings with the fact that morality was outward looking. Hutcheson’s attempt at this involved positing a unique mental faculty or sense that was part of human nature. Joseph Butler (1692–1752), on the other hand, sought to distance human morality from self-interest through a reflective process of conscience. They were all involved in seeking an answer to the same basic challenge: how can morality be explained by the sentiments without reducing it to whatever makes us feel good? It was this debate that Smith stepped into when he published The Theory of Moral Sentiments in 1759.
Notes
1 The general consensus among contemporary Smith scholars is that the Problem is a non-problem and based on a faulty reading by the German historical school. 2 Moral Sentiments, 287. 3 Also included in this volume is Smith’s short essay on the External Senses. This represents an engagement with the ideas of Berkeley and Locke on the nature of the relationship between our perception of external objects and the sensory organs of the body. 4 Astronomy, 33. 5 Astronomy, 41. 6 It is worth noting that this passage also marks the first of three appearances of the phrase ‘invisible hand’ in Smith’s works. Here the invisible hand is that of the Roman God Jupiter, marking the usage as distinct from the two later appearances of the term, which we will examine in subsequent chapters. 7 Astronomy, 50. 8 Astronomy, 45. 9 Astronomy, 96.10 Astronomy, 46.11 Astronomy, 66.12 Astronomy, 45.13 For a discussion of Smith on system, see Skinner, A System of Social Science; Phillipson, Adam Smith; and Schliesser, Adam Smith.14 Astronomy, 42.15 Astronomy, 74.16 Astronomy, 59.17 Ancient Physics, 107–8.18 Hutcheson, Inquiry, 39–40.19 Astronomy, 71.20 Astronomy, 89.21 The similarities between Smith’s theory and that of the twentieth-century philosopher of science Thomas Kuhn, with its division between normal science and paradigm shifts, has been widely noted, though it seems Kuhn was not aware of Smith’s essay as he developed his view.22 For a discussion of Smith’s relationship to Newtonianism see Montes, ‘Newtonianism and Smith’.23 The best short account of Smith’s theory of science is Berry, ‘Smith and Science’.24 Smith makes almost exactly the same observation in the Wealth of Nations when he points to ‘the beauty of systematical arrangement of different observations connected by a few common principles’ (Wealth of Nations, 768–9), and in his essay on the Imitative Arts published in the Essays on Philosophical Subjects showing how key it was to
