On the rationale of tolerance in Shaftesbury, Hutcheson, and Smith

The idea that human beings possess a moral sense is the characteristic of a certain branch of moral philosophy of the British Enlightenment. In this context, the question of tolerance appears as a condition that enables the moral sense to work properly. This article traces the connection between toleration and morality along Shatesbury's philosophy of politeness, via Hutcheson's conception of a moral philosophy based on "benevolence", to Smith's development of the "impartial spectator".
