There is in all men a sufficient remembrance of the original natural causes of pleasure to enable them to bring all things offered to their senses to that standard, and to regulate their feelings and opinions by it. Suppose one who had so vitiated his palate as to take more pleasure in the taste of opium than in that of butter or honey to be presented with a bolus of squills; there is hardly any doubt but that he would prefer the butter or honey to this nauseous morsel, or to any other bitter drug to which he had not been accustomed; which proves that his palate was naturally like that of other men in all things, that it is still like the palate of other men in many things, and only vitiated in some particular points. For in judging of any new thing, even of a taste similar to that which he has been formed by habit to like, he finds his palate affected in the natural manner and on the common principles. Thus the pleasure of all senses, of the sight, and even of the taste, that most ambiguous of the senses, is the same in all, high and low, learned and unlearned. Besides the ideas, with their annexed pains and pleasures, which are presented by the sense the mind of man possesses a sort of creative power of its own; either in representing at pleasure the images of things in the order and manner in which they were received by the senses, or in combining those images in a new manner, and according to a different order. This power is called imagination; and to this belongs whatever is called wit, fancy, invention, and the like. But it must be observed that the power of the imagination is incapable of producing anything absolutely new; it can only vary the disposition of those ideas which it has received from the senses. Now the imagination is the most extensive province of pleasure and pain, as it is the region of our fears and our hopes, and of all our passions that are connected with them; and whatever is calculated to affect the imagination with these commanding ideas, by force of any original natural impression, must have the same power pretty equally over all men. For since the imagination is only the representation of the senses, it can only be pleased or displeased with the images, from the same principle on which the sense is pleased or displeased with the realities; and consequently there must be just as close an agreement in the imaginations as in the senses of men. A little attention will convince us that this must of necessity be the case.
