The writer of a philosophical treatise may, I imagine, at this advanced era of human intellect, be held excused from entering into a controversy with those reasoners, if such there are, who would claim an exemption from its decrees in favour of any one among those diversified systems of obscure opinion respecting morals, which, under the name of religions, have in various ages and countries prevailed among mankind. Besides that if, as these reasoners have pretended, eternal torture or happiness will ensue as the consequence of certain actions, we should be no nearer the possession of a standard to determine what actions were right and wrong, even if this pretended revelation, which is by no means the case, had furnished us with a complete catalogue of them. The character of actions as virtuous or vicious would by no means be determined alone by the personal advantage or disadvantage of each moral agent individually considered. Indeed, an action is often virtuous in proportion to the greatness of the personal calamity which the author willingly draws upon himself by daring to perform it. It is because an action produces an overbalance of pleasure or pain to the greatest number of sentient beings, and not merely because its consequences are beneficial or injurious to the author of that action, that it is good or evil. Nay, this latter consideration has a tendency to pollute the purity of virtue, inasmuch as it consists in the motive rather than in the consequences of an action. A person who should labour for the happiness of mankind lest he should be tormented eternally in Hell, would, with reference to that motive, possess as little claim to the epithet of virtuous, as he who should torture, imprison, and burn them alive, a more usual and natural consequence of such principles, for the sake of the enjoyments of Heaven. My neighbour, presuming on his strength, may direct me to perform or to refrain from a particular action; indicating a certain arbitrary penalty in the event of disobedience within power to inflict. My action, if modified by his menaces, can no degree participate in virtue. He has afforded me no criterion as to what is right or wrong. A king, or an assembly of men, may publish a proclamation affixing any penalty to any particular action, but that is not immoral because such penalty is affixed. Nothing is more evident than that the epithet of virtue is inapplicable to the refraining from that action on account of the evil arbitrarily attached to it. If the action is in itself beneficial, virtue would rather consist in not refraining from it, but in firmly defying the personal consequences attached to its performance.
