The above interpretation suggests that Hume’s primary aim in his discussion “Of liberty and necessity” is to defend an account of moral freedom understood in terms of “liberty of spontaneity”. Our tendency to confuse this form of liberty with indifference is a result of a mistaken understanding of the nature of causation and necessity. The significance of Hume’s contribution, on this interpretation, rests largely with his application of his “new definition of necessity” to this issue. All this is, in turn, generally consistent with arguments by leading representatives of classical compatibilism who came after Hume (viz. Mill, Russell, Schlick, Ayer, et al). If this is an accurate and complete account of Hume’s approach then it is liable to all the objections that have been levelled against the classical compatibilist view.
