Now it may, in like manner, be objected to the present system, that if virtue and vice be determined by pleasure and pain, these qualities must, in every case, arise from the sensations; and consequently any object, whether animate or inanimate, rational or irrational, might become morally good or evil, provided it can excite a satisfaction or uneasiness. To which we may add, that this agreement or disagreement, not admitting of degrees, all virtues and vices would of course be equal. Wherever we can make an idea approach the impressions in force and vivacity, it will likewise imitate them in its influence on the mind; and vice versa, where it imitates them in that influence, as in the present case, this must proceed from its approaching them in force and vivacity. As to the third sense of the word, it is certain, that both vice and virtue are equally artificial, and out of nature.
The very essence of virtue, according to this hypothesis, is to produce pleasure and that of vice to give pain. Now it has been observed, that our own sensations determine the vice and virtue of any quality, as well as those sensations, which it may excite in others. Thus the course of the argument leads us to conclude, that since vice and virtue are not discoverable merely by reason, or the comparison of ideas, it must be by means of some impression or sentiment they occasion, that we are able to mark the difference betwixt them.
