This question is one by no means easy to answer, and the solution of it must obviously depend to some extent on the moral surroundings and prepossessions of the person who undertakes to answer it. But, attempting to take as wide a survey as possible of those acts which, in different persons, elicit moral approbation or disapprobation, I will endeavour to discriminate the characteristics which they have in common. All those acts, then, it seems to me, which elicit a distinctively moral feeling have been the result of some conflict amongst the various desires and affections, or, to adopt the more ordinary phraseology, of a conflict of motives. We neither approve nor disapprove of acts with regard to which there seems to have been little or no choice, which appear to have resulted naturally from the pre-existing circumstances. Thus, if a well-to-do man pays his debts promptly, or a man of known poverty asks to have the time of payment deferred, we neither visit the one with praise nor the other with censure, though, if their conduct were reversed, we should censure the former and praise the latter. The reason of this difference of treatment is plain. There is not, or at least need not be, any conflict, in the case of the well-to-do man, between his own convenience or any reasonable gratification of his desires and the satisfaction of a just claim. Hence, in paying the debt promptly, he is only acting as we might expect him to act, and his conduct excites no moral feeling on our part, though, if he were to act differently, he would incur our censure. The poor man, on the other hand, must have put himself to some inconvenience and exercised some self-denial in order to meet his engagement at the exact time at which the payment became due, and hence he merits our praise, though, if he had acted otherwise, the circumstances might have excused him. Another characteristic of acts which we praise or blame, in the case of others, or approve or disapprove, on reflexion, in our own case, seems to be that they must possess some importance. The great majority of our acts are too trivial to merit any notice, such as is implied in a moral judgment. When a man makes way for another in the street, or refrains from eating or drinking more than is good for him, neither he nor the bystander probably ever thinks of regarding the act as a meritorious one. It is taken as a matter of course, though the opposite conduct might, under certain circumstances, be of sufficient importance to incur censure. It is impossible here, as in most other cases where we speak of 'importance,' to draw a definite line, but it may at least be laid down that an act, in order to be regarded as moral or immoral, must be of sufficient importance to arrest attention, and stimulate reflexion.
