which are supposed to constitute the judgment, are not one sensation, but many. Now if it be meant that these single objects, as they are perceived separately, or successively, one by one, without the intervention of any reflex act of the mind combining and comparing them together, constitute of themselves the judgment, ‘that justice is preferable to mercy,’ this is to say, in so many words, that the mind forms a comparison between things without comparing them, and judges of their relations without perceiving them. On the other hand, if it be meant to include the acts of the mind in comparing, judging, inferring, &c. in the term _sensation_, then the proposition that judgment or sensation are the same, will be nothing but an idle and insignificant abuse of words, and will only prove that if to the sensation, or perception of particular objects we add the faculty of comparing and judging, nothing farther will be necessary for it to compare and judge. I shall therefore dismiss this well known maxim as no better than a misnomer, as an attempt to shorten the labour of thought by the interposition of an unmeaning phrase, and to confound all the distinctions of the understanding by an equivoque. It will not be amiss in this place to transcribe a passage from the Logic of the Abbé Condillac (a work which may be regarded as the quintessence of slender thought, and of the art of substituting words for things) to show how far the doctrine of the origin of all our ideas from sensation may be carried, and what an imbecility it produces in the mind, and deadness to any but external objects. The design of the passage is to prove that morality is a visible thing. This however is a work of supererogation, even on the principle supposed: for it is not necessary to refer morality to any thing visible or audible, or to any other of the senses, but the sense of pleasure and pain; our feelings of this kind being allowed to come from, and make a part of our original sensations. But this system is not an improvement on reason, but a progression in superficiality and absurdity, a vast vacuity, where ‘fluttering its pennons vain, the mind drops down ten thousand fathoms deep.’ ‘Moral ideas,’ says my author, ‘seem to elude the senses: they at least elude the senses of those philosophers who deny that our knowledge proceeds from sensation. They would gladly know of what colour virtue is, or of what colour vice is. I answer that virtue consists in the habitual performance of good actions, as vice consists in the habitual performance of bad ones. Now these habits and these actions are visible. ‘What, then, is the morality of actions a thing which falls under the cognizance of the senses! Wherefore should it not? Morality depends solely on the conformity between our actions and the laws; but these actions are visible, and the laws are so equally, since they are certain conventions made by men.
