An Aberdonian clergyman who opened a successful academy near London, John Adams (d. 1814) was an active popularizer of Enlightenment scholarship. In this work of 1789, reprinted here for the first time, Adams pieced together ideas from the works of Montesquieu and several of his Scottish disciples (including Kames, Monboddo and Dunbar) on human nature society, commerce, government, and related topics, in an effort "to Promote a Spirit of Enquiry in the British Youth of both Sexes".
