II. Ethical Theory embraces certain questions of pure PSYCHOLOGY.
1. The Psychological nature of Conscience, the Moral Sense, or by whatever name we designate the faculty of distinguishing right and wrong, together with the motive power to follow the one and eschew the other. That such a faculty exists is admitted. The question is, what is its place and origin in the mind?
On the one side, Conscience is held to be a unique and ultimate power of the mind, like the feeling of Resistance, the sense of Taste, or the consciousness of Agreement. On the other side, Conscience is viewed as a growth or derivation from other recognized properties of the mind. The Theory of the Standard (4) called the doctrine of the Moral Sense, proceeds upon the first view; on that theory, the Standard and the Faculty make properly but one question. All other theories are more or less compatible with the composite or derivative nature of Conscience; the supporters of Utility, in particular, adopt this alternative.
2. A second Psychological question, regarded by many (notably by Kant) as vitally implicated in Moral Obligation, is the Freedom of the Will. The history of opinion on this subject has been in great part already given.
3. Thirdly, It has been debated, on Psychological grounds, whether our Benevolent actions (which all admit) are ultimately modes of self-regard, or whether there be, in the human mind, a source of purely Disinterested conduct. The first view, or the reference of benevolence to Self, admits of degrees and varieties of statement.
(1) It may be held that in performing good actions, we expect and obtain an immediate reward fully equivalent to the sacrifice made. Occasionally we are rewarded in kind; but the reward most usually forthcoming (according to Mandeville), is praise or flattery, to which the human mind is acutely sensitive.
(2) Our constitution may be such that we are pained by the sight of an object in distress, and give assistance, to relieve ourselves of the pain. This was the view of Hobbes; and it is also admitted by Mandeville as a secondary motive.
(3) We may be so formed as to derive enjoyment from the performance of acts of kindness, in the same immediate way that we are gratified by warmth, flowers, or music; we should thus be moved to benevolence by an intrinsic pleasure, and not by extraneous consequences.
Bentham speaks of the pleasures and the pains of Benevolence, meaning that we derive pleasure from causing pleasure to others, and pain from the sight of pain in others.
(4) It may be affirmed that, although we have not by nature any purely disinterested impulses, these are generated in us by associations and habits, in a manner similar to the conversion of means into final ends, as in the case of money. This is the view propounded by James Mill, and by Mackintosh.
