The conduct of a man, who studies philosophy in this careless manner, is more truly sceptical than that of any one, who feeling inhimself an inclination to it, is yet so over-whelm'd with doubts and scruples, as totally to reject it. A true sceptic will be diffident of his philosophical doubts, as well as of his philosophical conviction; and will never refuse any innocent satisfaction, which offers itself, upon account of either of them.
