_Etymology of the Term._--To some extent the word itself may guide us. Borrowed, as are most if not all words expressing mental states and acts, from the sphere of sense, there was doubtless some reason why this word in particular was selected to denote the power of the mind now under consideration. Some close analogy, doubtless, was supposed to exist between the physical state denoted by this word in its primary sense, and the mental faculty to which we refer, so that, in seeking for a term by which to designate that intellectual faculty, none would more readily present itself, as appropriate and suggestive of the mental state intended, than the one in question. This analogy, whatever it be, while it cannot be taken as decisive of the question before us, is still an element not to be overlooked by the psychologist. What, then, is the analogy? How comes this word--_taste_--to be used, rather than any other, to denote the idea and power now under consideration? _Taste as a Sense._--In the domain of sense, certain objects brought in contact with the appropriate physical organ, affect us as sweet, sour, bitter, etc. This is purely an affection of the sensibility, mere feeling. We say the thing _tastes_ so and so. The power of distinguishing such qualities we call the power or sense of taste. Primarily mere sensation, mere feeling, we transfer the word to denote the power of judging by means of that sensation. There is, in the first instance, an affection of the organ by the object brought in contact with it, of which affection we are cognizant; then follows an intellectual perception or judgment that the object thus affecting us, possesses such and such qualities, is sweet, sour, bitter, salt, etc.. The sensation affords the ground of the judgment. The latter is based upon the former. The sensation, the simple feeling, affords the means of discriminating, judging, distinguishing, and to this latter power or process the word taste, in the physical sense, is more frequently appropriated. We say of such or such a man, his taste is acute, or his taste is impaired, or dull, etc., meaning his power of perceiving and distinguishing the various properties of objects which affect his sense of taste.
