Morality and Interest
Among the miscellany of philosophical achievements bequeathed us by the Enlightenment is the account, worked out by Hobbes, Locke, Hume and others, of the conditions for the existence of the kind of civil or commercial association that depends upon contract. The theory of civil association has subsequently exercised the kind of fascination for moral philosophers that a highly successful theory is apt to exercise in any field of enquiry: it has, that is, both inspired later writers and to some extent restricted their horizons.
