The inducements to perform a moral act, as, for example, the fulfilling of a bargain,—are plainly seen to be of various kinds.
(1) Prudence, or Self-interest, has obviously much to do with the moral conduct. Postponing for the present the consideration of Punishment, which is one mode of appeal to the prudential regards, we can trace the workings of self-interest on many occasions wherein men act right. To fulfil a bargain is, in the great majority of cases, for the advantage of the agent; if he fails to perform his part, others may do the same to him.
Our self-interest may look still farther. We may readily discover that if we set an example of injustice, it may be taken up and repeated to such a degree that we can count upon nothing; social security comes to an end, and individual existence, even if possible, would cease to be desirable.
A yet higher view of self-interest informs us, that by performing all our obligations to our fellows, we not only attain reciprocal performance, but generate mutual affections and sympathies, which greatly augment the happiness of life.
(2) Sympathy, or Fellow-feeling, the source of our disinterested actions, must next be taken into the account. It is a consequence of our sympathetic endowment that we revolt from inflicting pain on another, and even forego a certain satisfaction to self rather than be the occasion of suffering to a fellow creature. Moved thus, we perform many obligations on the ground of the misery (not our own) accruing from their neglect.
A considerable portion of human virtue springs directly from this source. If purely disinterested tendencies were withdrawn from the breast, the whole existence of humanity would be changed. Society might not be impossible; there are races where mutual sympathy barely exists: but the fulfilment of obligations, if always dependent on a sense of self-interest, would fail where that was not apparent. On the other hand, if we were on all occasions touched with the unhappiness to others immediately and remotely springing from our conduct—if sympathy were perfect and unfailing—we could hardly ever omit doing what was right.
(3) Our several Emotions or Passions may co-operate with Prudence and with Sympathy in a way to make both the one and the other more efficacious.
Prudence, in the shape of aversion to pain, is rendered more acute when the pain is accompanied with Fear. The perturbation of fear rises up as a deterring motive when dangers loom in the distance. One powerful check to the commission of injury is the retaliation of the sufferer, which is a danger of the vague and illimitable kind, calculated to create alarm.
Anger, or Resentment, also enters, in various ways, into our moral impulses. In one shape it has just been noticed. In concurrence with Self-interest and Sympathy, it heightens the feeling of reprobation against wrong-doers.
The Tender Emotion, and the Affections, uphold us in the performance of our duties to others, being an additional safeguard against injury to the objects of the feelings. It has already been shown how these emotions, while tending to coalesce with Sympathy proper, are yet distinguished from it.
