480 HISTORY OF PHILOSOPHY categories can be applied to the objects of moral distinctions. Nor, on the other hand, can moral distinctions be derived from causal reasoning, although naturally we can make causal inferences about moral distinctions. In the Humean account, moral distinctions must be impressions derived from a moral sense existing independently of any consideration of divine sanction. Hume, in effect, separates ethics from religion, though he admits that the idea of a divine pattern of reward and punishment may reinforce moral behavior. I have tried to give a brief summary of the book's main points, and I will now turn to what is necessarily a rather random and selective criticism of the many features and arguments Capaldi pursues. My first and main criticism is that Capaldi has been too ambitious in trying to cover the whole range of Hume's thought in a fairly small book. He would be the last to deny the extent and profundity of Hume's thought, and his reader is therefore left rather breathless as he is led on a gallop from one mountain top to another. Secondly, while fully accepting the importance of Newton as an influence on Hume, I see no reason to insist on its exclusiveness. Brief mention is made of Bayle, but Hutcheson is cast aside while lesser but influential figures like Mandeville are scarcely mentioned. The reader should be warned as well that there is a scholarly view that considers Hume to have been deluded about the extent of his own Newtonianism" and plenty of respectable support for putting him in the sensationalist tradtion of Locke and Berkeley.s No doubt Newton is, above all others, the leading influence on Hume, but in ideas, as in affairs, fruitfulness often results from a plurality of relationships. Other faults in the book seem to result from taking everything Hume said as gospel. Thus Capaldi says if Hume is mistaken, he is only mistaken about facts because Hume claimed to be concerned only with them. This is bad question begging. Nor when Hume firmly commits himself to psychologism, is there any reason why we need not point out that giving psychological explanations for moral behavior, though considerably advanced by Hume, need not be the end nor even the beginning of our questions about ethics. A passing tribute might have been made to Kant and to other externalists who rejected Hume's approach. Smaller points can be made about particular passages: thus, in a rather muddled paragraph Hume emerges as the Copernicus rather than the Newton of the social sciences (a term that I think, despite Hume's pretensions, we should be careful of using in the context of eighteenth-century studies). I would not like to leave the reader with the impression that these remarks mean that I did not enjoy Capaldi's book. He has given us plenty to think about in his analysis, and he surely demonstrates that the old, rigidified exegesis of textbook Hume is dead and buried and that we are now in a much more exciting.world of Hume scholarship.
