which are taken, from the souse of taste. A sour temper, bitter expressions, bitter curses, a bitter fate, are terms well and strongly understood by all. And we are altogether as well understood when we say, a sweet disposition, a sweet person, a sweet condition and the like. It is confessed, that custom and some other causes have made many deviations from the natural pleasures or pains which belong to these several tastes; but then the power of distinguishing between the natural and the acquired relish remains to the very last. A man frequently comes to prefer the taste of tobacco to that of sugar, and the flavor of vinegar to that of milk; but this makes no confusion in tastes, whilst he is sensible that the tobacco and vinegar are not sweet, and whilst he knows that habit alone has reconciled his palate to these alien pleasures. Even with such a person we may speak, and with sufficient precision, concerning tastes. But should any man be found who declares, that to him tobacco has a taste like sugar, and that he cannot distinguish between milk and vinegar; or that tobacco and vinegar are sweet, milk bitter, and sugar sour; we immediately conclude that the organs of this man are out of order, and that his palate is utterly vitiated. We are as far from conferring with such a person upon tastes, as from reasoning concerning the relations of quantity with one who should deny that all the parts together were equal to the whole. We do not call a man of this kind wrong in his notions, but absolutely mad. Exceptions of this sort, in either way, do not at all impeach our general rule, nor make us conclude that men have various principles concerning the relations of quantity or the taste of things. So that when it is said, taste cannot be disputed, it can only mean, that no one can strictly answer what pleasure or pain some particular man may find from the taste of some particular thing. This indeed cannot be disputed; but we may dispute, and with sufficient clearness too, concerning the things which are naturally pleasing or disagreeable to the sense. But when we talk of any peculiar or acquired relish, then we must know the habits, the prejudices, or the distempers of this particular man, and we must draw our conclusion from those.
