Dividing the world of mind into its three most immediately obvious distinctions, we have the Pure Intellect, Taste, and the Moral Sense. I place Taste in the middle because it is just this position which in the mind it occupies. It holds intimate relations with either extreme; but from the Moral Sense is separated by so faint a difference that Aristotle has not hesitated to place some of its operations among the virtues themselves. Nevertheless we find the offices of the trio marked with a sufficient distinction. Just as the Intellect concerns itself with Truth, so Taste informs us of the Beautiful, while the Moral Sense is regardful of Duty. Of this latter, while Conscience teaches the obligation, and Reason the expediency, Taste contents herself with displaying the charms, waging war upon Vice solely on the ground of her deformity, her disproportion, her animosity to the fitting, to the appropriate, to the harmonious, in a word, to Beauty.
