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. But supposing this hypothesis of moral philosophy should be allowed to be false, it is still evident, that pain and pleasure, if not the causes of vice and virtue, are at least inseparable from them. In general, it may be affirmed, that there is no such passion in human minds, as the love of mankind, merely as such, independent of personal qualities, of services, or of relation to ourseit It is true, there is no human, and indeed no sensible, creature, whose happiness or misery does not, in some measure, affect us when brought near to us, and represented in lively colours: But this proceeds merely from sympathy, and is no proof of such an universal affection to mankind, since this concern extends itself beyond our own species. 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. 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.
