§ 2. Let us now return to the question whether Wisdom, as exhibited in right judgment as to ends, is in any degree attainable at will, and so, according to our definition, a Virtue. At first sight, the perception of the right end may seem not to be voluntary any more than the cognition of any other kind of truth; and though in most cases the attainment of truth requires voluntary effort, still we do not generally think it possible for any man, by this alone, to attain even approximately the right solution of a difficult intellectual problem. It is often said, however, that the cognition of Moral truth depends largely upon the ‘heart,’ that is, upon a certain condition of our desires and other emotions: and it would seem to be on this view that Wisdom is regarded as a Virtue; and we may admit it as such, according to the definition before given, so far as this condition of feeling is attainable at will. Still, on closer scrutiny, there hardly seems to be agreement as to the right emotional conditions of the cognition of ends: as some would say that prayer or ardent aspiration produced the most favourable state, while others would urge that emotional excitement is likely to perturb the judgment, and would say that we need for right apprehension rather tranquillity of feeling: and some would contend that a complete suppression of selfish impulses was the essential condition, while others would regard this as chimerical and impossible, or, if possible, a plain misdirection of effort. On these points we cannot decide in the name of Common Sense: but it would be generally agreed that there are certain violent passions and sensual appetites which are known to be liable to pervert moral apprehensions, and that these are to some extent under the control of the Will; so that a man who exercises moral effort to resist their influence, when he wishes to decide on ends of action, may be said to be so far voluntarily wise.
