Alongside the mercantilist and metrocentic strain in civil philosophy in the 1730s, there was also an anti-imperial and philocolonial strand. This was represented most notably by the Hiberno-Scot Francis Hutcheson’s A System of Moral Philosophy, which he composed between 1734 and 1737, in the period before the anti-Spanish agitations but in the aftermath of the Excise Crisis and the darkest days of Walpole’s premiership. Hutcheson questioned the very foundations in rights of dominium upon which the British Empire rested, and argued that ‘[n]o person or society…can by mere occupation acquire such a right in a vast tract of land quite beyond their power to cultivate’. This denial of the juridical basis on which the British Empire in America was claimed was in its own way as Lockean as that of the author of the Essay on Civil Government, but took seriously Locke’s sufficiency condition for legitimate possession. Hutcheson went even further, and proposed colonial independence should the mother-country impose ‘severe and absolute’ power over its provinces. ‘The insisting on old claims and tacit conventions’, he concluded, ‘to extend civil power over distant nations, and form grand unwieldy empires, without regard to the obvious maxims of humanity, has been one great source of human misery’.
