A recent invitation to talk to the Enlightenment Workshop of the Voltaire Foundation prompted me to consider the ways in which some modes of thinking common during the Enlightenment might have been inherited – directly or indirectly – from the English idea of ‘improvement’, a topic on which I had been working. By ‘improvement’ I refer to a word and a culture which were invented in England in the seventeenth century and had their most notable effects, at least initially, at home. Other countries might have been striving for improvement in practice in one way or another at the same time, but the English found a word which embraced every aspect of it, and fashioned out of it a frame of mind which had remarkable consequences.
The word ‘improve’ was first coined in England in the later fifteenth century, and it meant to make a profit from land. By the early seventeenth century the notion and word were being extended, by Francis Bacon, for example, who described learning as capable of being ‘improved and converted by the industry of man’. Then in the 1640s and 1650s the word was extended further by the Baconian reformers in the group led by the Prussian emigre Samuel Hartlib, some of whom went on to become founders of the Royal Society. Hartlib himself was most interested in promoting agricultural improvement, but the word and concept were already being applied to trade and banks, and were soon used about almost everything – including navigable rivers, fire engines, military power and the relief of the poor.
Much of this was propaganda for particular projects, and intended to profit their advocates. But improvers also had to their credit two major innovations in thinking about economic behaviour and the economy in general – two crucial components which English improvement carried with it into the eighteenth century. The first was the explicit defence of consumer appetites and luxury as legitimate roads to national wealth. In the 1670s Nicholas Barbon led a reaction against contemporary criticism of London as a monster consuming the wealth of the nation. Instead he pictured competitive consumption as the consequence of ‘emulation’, and a positive cause of both individual and national improvement. According to Barbon, ‘all men by a perpetual industry’ were ‘struggling to mend their former condition; and thus the people grow rich’. Here, for the first time, some of the moral brakes on economic appetites were being deliberately and explicitly relaxed. A whole generation before Bernard Mandeville’s infamous Fable of the Bees, self-interest was being presented as identical to the public interest.

The second intellectual innovation of the 1670s was the work of William Petty, whose tract, Political Arithmetick, advertised the method he had invented for conceptualising, analysing, and measuring the wealth and resources of states. Petty used it to produce for England the first set of national accounts ever devised, and from it he developed a wholly new kind of political economy which he manipulated to show how the power and wealth of England would soon rival those of France. While Barbon opened the way to unrestrained economic appetites, one might say, Petty showed how their consequences could be measured and predicted.
When it came to the realities of England’s economic performance after 1688, therefore, the slogan of improvement was everywhere to be seen. It was wielded by advocates of the Bank of England in 1694, by supporters of the Union with Scotland in 1707, and by a crowd of promoters of trading and insurance companies and transport improvements, on whose often hazardous enterprises England’s economic success ultimately depended. By the 1720s, when Daniel Defoe publicised England as the greatest ‘trading improving nation’ in the world, ‘improvement’ had become shorthand for describing and justifying the dedication of the English to the pursuit of every kind of national and personal well-being.

By the 1720s too, improvement appeared to have delivered the goods. We now know that the national income had increased rapidly in the later seventeenth century; and since the population of England had stopped growing, income per head – the standard of living – had risen even more rapidly, probably by about fifty per cent in half a century, an astonishing achievement. Improvement seemed to have created England’s material affluence, and it is no accident that in the years around 1700 the word ‘affluence’ began to be used with its modern meaning, and that ‘progress’ began to be commonly applied to material progress. It was inevitable that so successful a culture should attract foreign admirers, visitors like Voltaire who came to learn its secrets, and politicians in other states who hoped, as David Hume observed, to ‘emulate’ England and adopt improvements of their own.
The full force of an improvement culture naturally travelled first and most successfully to other English dominions, to Ireland and Scotland, and especially, and with the greatest impact, to the English colonies in America, where both Benjamin Franklin and Thomas Jefferson found ‘inventions of improvement’ proliferating in endless sequence. The language of English improvement moved less easily across the Channel because it needed translation, but that was no obstacle to the transmission of the intellectual content which lay beneath the word, and least of all to the transmission of English political economy. Its influence was notable, for example, in translations of John Law’s tract on improvement, Money and Trade (1705), into French and German in 1720, and in other economic works written in Paris at the time, which drew on English examples, like the three volumes by Ernst Ludwig Carl, Traité de la Richesse des Princes (1723), which pointed to England’s material improvement and economic progress, and Jean-François Melon’s Essai politique sur le commerce (1734), which had a chapter on political arithmetic, and an argument that France must imitate English industry if there was to be similar economic ‘progress’ there.
John Law, by Alexis Simon Belle (c. 1715-20).
The most weighty testimony to the impact of improvement in France came in the first volume of the Encyclopédie, where Diderot himself, in a long entry on ‘arithmétique politique’, paid tribute to Petty as the first practitioner of a quantitative science indispensable for any politician concerned with trying to ensure the prosperity of a state by every possible means, including ‘la perfection de l’agriculture’. It is interesting to note that the word ‘perfection’ was used again for ‘improvement’ in translations into French of some of the works of Hume and Adam Smith also written in the 1750s. The common vocabulary suggests that something of the persuasive power of improvement had become part of what one might call Enlightenment thinking.
There were doubtless other sources, besides the writings of English improvers, which contributed to similar ways of thinking; and it is undeniable that there were whole sectors of Enlightenment thought to which English authors made little contribution. Nonetheless, when historians of the Enlightenment seek to identify its greatest contribution to Western thought, and point – as some of them do – to a new political economy aimed at ‘human betterment’, they are paying tribute to English writers on improvement of the second half of the seventeenth century. They had been the first to build a whole culture around the notion that individuals, societies and states had the capacity to ‘mend their condition’ (as Barbon put it) and to demonstrate practical ways of going about it.
