The chief elementary feelings that go to constitute the moral sentiments appear to be Gratitude, Pity, Resentment, and Shame. To take the example of Gratitude. Acts of beneficence to ourselves give us pleasure; we associate this pleasure with the benefactor, so as to regard him with a feeling of complacency; and when we view other beneficent beings and acts there is awakened within us our own agreeable experience. The process is seen in the child, who contracts towards the nurse or mother all the feelings of complacency arising from repeated pleasures, and extends these by similarity to other resembling persons. As soon as complacency takes the form of action, it becomes (according to the author's theory, connecting conscience with will), a part of the Conscience. So much for the development of Gratitude. Next as to Pity. The likeness of the outward signs of emotion makes us transfer to others our own feelings, and thereby becomes, even more than gratitude, a source of benevolence; being one of the first motives to impart the benefits connected with affection. In our sympathy with the sufferer, we cannot but approve the actions that relieve suffering, and the dispositions that prompt them. We also enter into his Resentment, or anger towards the causes of pain, and the actions and dispositions corresponding; and this sympathetic anger is at length detached from special cases and extended to all wrong-doers; and is the root of the most indispensable compound of our moral faculties, the 'Sense of Justice.'
To these internal growths, from Gratitude, Pity, and Resentment, must be added the education by means of well-framed penal laws, which are the lasting declaration of the moral indignation of mankind. These laws may be obeyed as mere compulsory duties; but with the generous sentiments concurring, men may rise above duty to virtue, and may contract that excellence of nature whence acts of beneficence flow of their own accord.
He next explains the growth of Remorse, as another element of the Moral Sense. The abhorrence that we feel for bad actions is extended to the agent; and, in spite of certain obstacles to its full manifestation, that abhorrence is prompted when the agent is self.
The theory of derivation is bound to account for the fact, recognized in the language of mankind, that the Moral Faculty is ONE. The principle of association would account for the fusion of many different sentiments into one product, wherein the component parts would cease to be discerned; but this is not enough. Why do these particular sentiments and no others coalesce in the total—Conscience. The answer is what was formerly given with reference to Butler; namely, while all other feelings relate to outward objects, the feelings brought together in conscience, contemplate exclusively the dispositions and actions of voluntary agents. Conscience is thus an acquired faculty, but one that is universally and necessarily acquired.
The derivation is farther exemplified by a comparison with the feelings of Taste. These may have an original reference to fitness—as in the beauty of a horse—but they do not attain their proper character until the consideration of fitness disappears. So far they resemble the moral faculty. They differ from it, however, in this, that taste ends in passive contemplation or quiescent delight; conscience looks solely to the acts and dispositions of voluntary agents. This is the author's favourite way of expressing what is otherwise called the authority and supremacy of conscience.
To sum up:—the principal constituents of the moral sense are
Gratitude, Sympathy (or Pity), Resentment, and Shame; the secondary and
auxiliary causes are Education, Imitation, General Opinion, Laws and
Government.
In criticising Paley, he illustrates forcibly the position, that
Religion must pre-suppose morality.
His criticism of Bentham gives him an opportunity of remarking on the modes of carrying into effect the principle of Utility as the Standard. He repeats his favourite doctrine of the inherent pleasures of a virtuous disposition, as the grand circumstance rendering virtue profitable and vice unprofitable. He even uses the Platonic figure, and compares vice to mental distemper. It is his complaint against Bentham and the later supporters of Utility, that they have misplaced the application of the principle, and have encouraged the too frequent appeal to calculation in the details of conduct. Hence arise sophistical evasions of moral rules; men will slide from general to particular consequences; apply the test of utility to actions and not to dispositions; and, in short, take too much upon themselves in settling questions of moral right and wrong. [He might have remarked that the power of perverting the standard to individual interests is not confined to the followers of Utility.] He introduces the saying attributed to Andrew Fletcher, 'that he would lose his life to serve his country, but would not do a base thing to save it.'
He farther remarks on the tendency of Bentham and his followers to treat Ethics too juridically. He would probably admit that Ethics is strictly speaking a code of laws, but draws the line between it and the juridical code, by the distinction of dispositions and actions. We may have to approve the author of an injurious action, because it is well-meant; the law must nevertheless punish it. Herein Ethics has its alliance with Religion, which looks at the disposition or the heart.
He is disappointed at finding that Dugald Stewart, who made applications of the law of association and appreciated its powers, held back from, and discountenanced, the attempt of Hartley to resolve the Moral Sense, styling it 'an ingenious refinement on the Selfish system,' and representing those opposed to himself in Ethics as deriving the affections from 'self-love.' He repeats that the derivation theory affirms the disinterestedness of human actions as strongly as Butler himself; while it gets over the objection from the multiplication of original principles; and ascribes the result to the operation of a real agent.
