Margaret Jacob and Jonathan Israel have offered somewhat different accounts of what they call the ‘Radical Enlightenment’, that is those elements of enlightenment thought which resulted in the radical political upheavals of the late eighteenth century and the rise of democratic republicanism. Jonathan Israel, in particular, insists that the radical enlightenment was radical both in its secular rejection of all providentialist and teleological metaphysics, as well as radical in its democratic tendencies. This paper looks at the way in which Catharine (...) Macaulay’s very influential defence of the equal rights of men, during the lead up to the American and French revolutions, poses problems for Israel’s account of the radical enlightenment and argues that the religious foundation of her political radicalism was characteristic of many of her contemporaries and fits in better with Jacob’s more ecumenical account of the radical enlightenment than with Israel’s purely secular characterisation.
