Religion affords such strong motives to the practice of virtue, and guards us by such powerful restraints from the temptations of vice, that many have been led to suppose, that religious principles were the sole laudable motives of action. We ought neither, they said, to reward from gratitude, nor punish from resentment; we ought neither to protect the helplessness of our children, nor afford support to the infirmities of our parents, from natural affection. All affections for particular objects, ought to be extinguished in our breast, and one great affection take the place of all others, the love of the Deity, the desire of rendering ourselves agreeable to him, and of directing our conduct in every respect according to his will. We ought not to be grateful from gratitude, we ought not to be charitable from humanity, we ought not to be public-spirited from the love of our country, nor generous and just from the love of mankind. The sole principle and motive of our conduct in the performance of all those different duties, ought to be a sense that God has commanded us to perform them. I shall not at present take time to examine this opinion particularly; I shall only observe, that we should not have expected to have found it entertained by any sect, who professed themselves of a religion in which, as it is the first precept to love the Lord our God with all our heart, with all our soul, and with all our strength, so it is the second to love our neighbour as we love ourselves; and we love ourselves surely for our own sakes, and not merely because we are commanded to do so. That the sense of duty should be the sole principle of our conduct, is no where the precept of Christianity; but that it should be the ruling and governing one, as philosophy, and as, indeed, common sense directs. It may be a question however, in what cases our actions ought to arise chiefly or entirely from a sense of duty, or from a regard to general rules; and in what cases some other sentiment or affection ought to concur, and have a principal influence. The decision of this question, which cannot, perhaps, be given with any very great accuracy, will depend upon two different circumstances; first, upon the natural agreeableness or deformity of the sentiment or affection which would prompt us to any action independent of all regard to general rules; and secondly, upon the precision and exactness, or the looseness and inaccuracy of the general rules themselves. I. First, I say, it will depend upon the natural agreeableness or deformity of the affection itself, how far our actions ought to arise from it, or entirely proceed from a regard to the general rule.
