They must necessarily be placed either in ourselves or others, and excite either pleasure or uneasiness; and therefore must give rise to one of these four passions; which clearly distinguishes them from the pleasure and pain arising from inanimate objects, that often bear no relation to us: And this is, perhaps, the most considerable effect that virtue and vice have upon the human mind. If you assert, that vice and virtue consist in relations susceptible of certainty and demonstration, you must confine yourself to those four relations, which alone admit of that degree of evidence; and in that case you run into absurdities, from which you will never be able to extricate yourself. 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 it is certain, that self-love, when it acts at its liberty, instead of engaging us to honest actions, is the source of all injustice and violence; nor can a man ever correct those vices, without correcting and restraining the natural movements of that appetite. The pain or pleasure, which arises from the general survey or view of any action or quality of the mind, constitutes its vice or virtue, and gives rise to our approbation or blame, which is nothing but a fainter and more imperceptible love or hatred. But however directly the distinction of vice and virtue may seem to flow from the immediate pleasure or uneasiness, which particular qualities cause to ourselves or others; it is easy to observe, that it has also a considerable dependence on the principle of sympathy so often insisted on. But to make the matter still more certain, I alter the object; and instead of vice and virtue, make the trial upon beauty and deformity, riches and poverty, power and servitude.
