Vision, a word expressive of the phenomena of {24} sight, is ambiguous in the same manner. It is sometimes used to denote the sense of seeing; that is, the antecedent and consequent, as explained in the preceding paragraph. Thus we say, the phenomena of vision, with the same propriety as we say the phenomena of sight. It is sometimes employed to denote the sensation. If we ask what feeling a blind man is deprived of, it would be perfectly proper to say, vision is the feeling of which he is deprived. It is, also, employed to denote the object. What vision was that? would be a very intelligible question, on the sudden appearance and disappearance of something which attracted the eye.[6] [Editor's footnote 6: Vision, I believe, is used to denote the object of sight, only when it is supposed that this object is something unreal, _i.e._, that it has not any extended and resisting substance behind it: or rhetorically, to signify that the object looks more like a phantom than a reality; as when Burke calls Marie Antoinette, as once seen by him, a delightful vision.--_Ed._] {25} SECTION IV. TASTE. The ORGAN of TASTE is in the mouth and fauces. In ordinary language, the OBJECT of taste is any thing, which, taken into the mouth, and tasted, as it is called, produces the peculiar SENSATION of this sense. Nor has philosophy as yet enabled us to state the object of taste more correctly. There are experiments which show, that galvanism is concerned in the phenomena, but not in what way. The SENSATION, in this case, is distinguished by every body. The taste of sugar, the taste of an apple, are words which immediately recall the ideas of distinct feelings. It is to be observed, however, that the feelings of this sense are very often united with those of the sense of smell; the two organs being often affected by the same thing, at the same time. In that case, though we have two sensations, they are so intimately blended as to seem but one; and the flavour of the apple, the flavour of the wine, appears to be a simple sensation, though compounded of taste and smell.[7] [Editor's footnote 7: Some physiologists have been of opinion that a large proportion of what are classed as tastes, including all flavours, as distinguished from the generic tastes of sweet, sour, bitter, &c., are really affections of the nerves of smell, and are mistaken for tastes only because they are experienced along with tastes, as a consequence of taking food into the mouth.--_Ed._]
