I. First of all is the question as to the ETHICAL STANDARD. What, in the last resort, is the test, criterion, umpire, appeal, or Standard, in determining Right and Wrong? In the concrete language of Paley, "Why am I obliged to keep my word? The answer to this is the Theory of Right and Wrong, the essential part of every Ethical System."
We may quote the leading answers, as both explaining and summarizing the chief question of Ethics, and more especially of Modern Ethics.
1. It is alleged that the arbitrary Will of the Deity, as expressed in the Bible, is the ultimate standard. On this view anything thus commanded is right, whatever be its consequences, or however it may clash with our sentiments and reasonings.
2. It was maintained by Hobbes, that the Sovereign, acting under his responsibility to God, is the sole arbiter of Right and Wrong. As regards Obligatory Morality, this seems at first sight an identical proposition; morality is another name for law and sovereignty. In the view of Hobbes, however, the sovereign should be a single person, of absolute authority, humanly irresponsible, and irremoveable; a type of sovereignty repudiated by civilized nations.
3. It has been held, in various phraseology, that a certain fitness, suitability, or propriety in actions, as determined by our Understanding or Reason, is the ultimate test. "When a man keeps his word, there is a certain congruity or consistency between the action and the occasion, between the making of a promise and its fulfilment; and wherever such congruity is discernible, the action is right." This is the view of Cudworth, Clarke, and Price. It may be called the Intellectual or Rational theory.
A special and more abstract form of the same theory is presented in the dictum of Kant—'act in such a way that your conduct might be a law to all beings.'
4. It is contended, that the human mind possesses an intuition or instinct, whereby we feel or discern at once the right from the wrong; a view termed the doctrine of the Moral Sense, or Moral Sentiment. Besides being supported by numerous theorizers in Ethics, this is the prevailing and popular doctrine; it underlies most of the language of moral suasion. The difficulties attending the stricter interpretation of it have led to various modes of qualifying and explaining it, as will afterwards appear. Shaftesbury and Hutcheson are more especially identified with the enunciation of this doctrine in its modern aspect.
5. It was put forth by Mandeville that Self-interest is the only test of moral rightness. Self-preservation is the first law of being; and even when we are labouring for the good of others, we are still having regard to our own interest.
6. The theory called, Utility, and Utilitarianism, supposes that the well-being or happiness of mankind is the sole end, and ultimate standard of morality. The agent takes account both of his own happiness and of the happiness of others, subordinating, on proper occasions, the first to the second. This theory is definite in its opposition to all the others, but admits of considerable latitude of view within itself. Stoicism and Epicureanism, are both included in its compass.
The two last-named theories—Self-Interest, and Utility or the Common Well-Being, have exclusive regard to the consequences of actions; the others assign to consequences a subordinate position. The terms External and Dependent are also used to express the reference to Happiness as the end: Internal and Independent are the contrasting epithets.
