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 continue the experiment, I change anew the relation of ideas, and suppose the vice to belong to myself. For in the first sense of the word, Nature, as opposed to miracles, both vice and virtue are equally natural; and in the second sense, as opposed to what is unusual, perhaps virtue will be found to be the most unnatural. For granting that morality had no foundation in nature, it must still be allowed, that vice and virtue, either from self-interest or the prejudices of education, produce in us a real pain and pleasure; and this we may observe to be strenuously asserted by the defenders of that hypothesis. In the former example, my perceptions in the apprehension of a house might begin at the roof and end at the foundation, or vice versa; or I might apprehend the manifold in this empirical intuition, by going from left to right, and from right to left. It is impossible, therefore, that the character of natural and unnatural can ever, in any sense, mark the boundaries of vice and virtue. No one will deny, that a negligence in this particular is a fault; and as faults are nothing but smaller vices, and this fault can have no other origin than the uneasy sensation, which it excites in others, we may in this instance, seemingly so trivial, dearly discover the origin of the moral distinction of vice and virtue in other instances.
