Hume's Refutation of — Wollaston?

192 HUME'S REFUTATION OF — WOLLASTON? Recently while rereading Book III of Hume's Treatise I was struck by an anomaly in the text that I had never noticed before. It consists in the juxtaposition of two arguments Hume offers regarding the source of the moral qualities of our actions. At first I dismissed Hume's arrangement of these arguments as being of little consequence — one of them appears in a footnote — but the more I thought about the juxtaposition the more it intrigued and puzzled me. Expecting that it must have been noted by other readers I checked through the literature to find some discussion of it. Since after a long search I have failed to uncover anything, and believing the point, which relates to Hume's central view concerning morality, to be of some interest, I have decided to write this brief paper. Two passages from § 1, entitled "Moral Distinctions not deriv'd from Reason," of Part I, Book III, are involved. Hume begins the section by arguing that, because of the limited scope of its capacities, reason cannot distinguish between right and wrong or, as he puts it, between virtue and vice, and therefore that it is a mistake to speak of actions as being reasonable or unreasonable. Since Hume's views on this question are well-known and since they are not directly relevant to the point of my paper, I shall not pursue them further, but turn directly to the issue at hand. After having stated his argument at the beginning of § 1 and reached the conclusion that "actions may be laudable or blameable, but they cannot be reasonable or unreasonable," Hume turns to answer an objection that might be made against him by a rationalist ethicist. He writes: 193 But perhaps it may be said, that tho' no will or action can be immediately contradictory to reason, yet we may find such a contradiction in some of the attendants of the action, that is, in its causes or effects (T 459). Pursuing this objection, Hume first considers the causes of our actions. He acknowledges that we can be led astray in what we do in two ways; by making mistakes of fact, first, about the nature of some object we desire (e.g. , thinking some fruit delicious when it really is not) and, second, about the means we should employ to gain the object (e.g. , attempting to pluck the fruit when it is beyond our reach). Although these errors cause us to act in ways that may be termed unreasonable in a "figurative and improper way of speaking" (T 459), they cannot be the source of any immorality in what we do because they are committed involuntarily and innocently. A person who falls into such errors and acts on them is "more to be lamented than blam'd" (T 459). To conclude his answer to the rationalistic objection he has raised, Hume turns next to the issue of whether the immorality of our actions can be explained in terms of the unreasonableness of any of their effects. In a memorable passage he denies that the fact that false judgments are the effects of our actions can be the source of immorality in what we do. As to those judgments which are the effects of our actions, and which, when false, give occasion to pronounce the actions contrary to truth and reason; we may observe, that our actions never cause any judgment, either true or false, in ourselves, and that 'tis only on others they have such an influence. 'Tis certain, that an action, on many occasions, may give rise to false conclusions in others; and that a 194 person, who thro' a window sees any lewd behaviour of mine with my neighbour's wife, may be so simple as to imagine she is certainly my own. In this respect my action resembles somewhat a lye or falshood; only with this difference, which is material, that I perform not the action with any intention of giving rise to a false judgment in another, but merely to satisfy my lust and passion. It causes, however, a mistake and false judgment by accident; and the falshood...
