A definition may be very exact, and yet go but a very little way toward informing us of the nature of the thing defined; but let the virtue of a definition be what it will, in the order of things, it seems rather to follow than to precede our inquiry, of which it ought to be considered as the result. It must be acknowledged that the methods of disquisition and teaching may be sometimes different, and on very good reason undoubtedly; but for my part, I am convinced that the method of teaching which approaches most nearly to the method of investigation is incomparably the best; since, not content with serving up a few barren and lifeless truths, it leads to the stock on which they grew; it tends to set the reader himself in the track of invention, and to direct him into those paths in which the author has made his own discoveries, if he should be so happy as to have made any that are valuable. But to cut off all pretense for caviling, I mean by the word Taste no more than that faculty or those faculties of the mind which are affected with, or which form a judgment of, the works of imagination and the elegant arts. This is, I think the most general idea of that word, and what is the least connected with any particular theory. And my point in this inquiry is, to find whether there are any principles on which the imagination is affected, so common to all, so grounded and certain, as to supply the means of reasoning satisfactorily about them. And such principles of taste I fancy there are, however paradoxical it may seem to those who on a superficial view imagine that there is so great a diversity of tastes, both in kind and degree, that nothing can be more determinate. All the natural powers in man, which I know, that are conversant about external objects are the senses, the imagination, and the judgment. And first with regard to the senses. We do and we must suppose, that as the conformation of their organs are nearly or altogether the same in all men, so the manner of perceiving external objects is in all men the same, or with little difference. We are satisfied that what appears to be light to one eye appears light to another; that what seems sweet to one palate is sweet to another; that what is dark and bitter to this man is likewise dark and bitter to that; and we conclude in the same manner of great and little, hard and soft, hot and cold, rough and smooth; and indeed of all the natural qualities and affections of bodies. If we suffer ourselves to imagine that their senses present to different men different images of things this skeptical proceeding will make every sort of reasoning on every subject vain and frivolous, even that skeptical reasoning itself which had persuaded us to entertain a doubt concerning the agreement of our perceptions.
