One of the most persistent issues of contemporary moral theory is the possibility of inferring moral judgments from factual nonmoral judgments. Another way of stating this issue is to inquire into the possibility of inferring "ought-judgments" from "is-judgments." It is generally accepted that the first person to deny the possibility of this inference was David Hume. The denial is supposed to be articulated in the last paragraph of the section of A Treatise of Human Nature entitled "Moral Distinctions not derived (...) from Reason," pages 469-470 in the Selby-Bigge edition. Hereafter I shall refer to this paragraph, the "is-oughtparagraph," as (I-0). The purpose of this article is to show that in (I-0) Hume makes no such denial, and to outline the implications of this revelation. (shrink)
