In lieu of an abstract, here is a brief excerpt of the content:77 KEMP SMITH, HUME AND THE PARALLELISM BETWEEN REASON AND MORALITY In a letter to a physician written in 1734 Hume expressed a dissatisfaction with the current state of philosophy and criticism, a dissatisfaction which he said had led him to strike out on his own and "seek out some new Medium, by which Truth might be establisht." He then went on to claim success: "After much Study, & (...) Reflection on this, at last, when I was about 18 Years of Age, there seem'd to be open'd up to me a new Scene of Thought, which transported me beyond Measure, & made me, with an Ardor natural to young men, throw up every other Pleasure or Business to apply entirely to it..." The wording suggests that the new Scene of Thought was a clear revelation, but nowhere does Hume tell us what the revelation was. (A clue, perhaps, is to be found in the "Abstract," where Hume says that if anything entitles him to the name of an inventor, "it is the use he makes of 2 the principle of the association of ideas.") Kemp Smith is convinced, however, that he knows what the new Scene of Thought was. According to Kemp Smith, Hume had already discovered that morality rests on feeling alone and depends in no way on insight or evidence, and the new discovery was simply the sudden realization that belief is equally independent of these considerations. I will argue in this paper that the great difficulty in this interpretation is that in those sections of the Treatise and the second Enquiry in which Hume expounds what could be called his moral epistemology he is concerned with pointing out what he considers to be important differences between reason and taste and between understanding and morality. I am not, however, questioning the validity of Kemp Smith's naturalistic interpretation, if it is broadly construed. 78 A curiosity of Kemp Smith's exposition is his citing of passages from Hume, which at first glance anyway seem to weaken, rather than strengthen, his case for the parallelism of moral and factual judgments. I will give two examples, the first being a quotation from the Green and Grose edition of the Enquiry. That Faculty, by which we discern Truth and Falsehood, and that by which we perceive Vice and Virtue had long been confounded with each other, and all Morality was suppos'd to be built on eternal and immutable Relations, which, to every intelligent Mind, were equally invariable as any Proposition concerning Quantity or Number. But a late Philosopher [Mr. Hutcheson, added as a note] has taught us, by the most convincing Arguments, that Morality is nothing in the abstract Nature of Things, but is entirely relative to the Sentiment or mental Taste of each particular [i.e. species] of Being; in the same Manner as the distinctions of sweet and bitter, hot and cold, arise from the particular feeling of each Sense or Organ. Moral Perceptions, therefore, ought not to be class 'd with the Operations of the Understanding, but with the Tastes or Sentiments. On the next page of this book Kemp Smith refers to this passage as part of the evidence for his claim that "the view here taken of our moral judgments of approval and disapproval can be extended to our beliefs regarding matters of fact and existence, and that 'logic', morals and 'criticism' may thus be brought 4 within the scope of the same general principles." The reference to "external and immutable Relations" may have led Kemp Smith to believe that Hume's thesis in this paragraph is the contrast between demonstrative and other kinds of judgment, but the last sentence is a decisive refutation of that interpretation. Hume frequently uses the term "understanding" to refer to causal reasoning, though in this sentence he seems to be using the term in 79 the more inclusive sense that would include demonstration and relations of ideas as well. But I know of no instances in which "understanding" is restricted to what Hume calls science, i.e., demonstration. Kemp Smith also quotes from the last section of Appendix I to the second Enquiry. This passage, appearing in the Selby-Bigge... (shrink)
