With the general spirit of these utterances the typical intuitionist is in sympathy, although he need not assent to the doctrine of innate ideas, nor need he hold that all moral truths are equally self-evident. There are intuitionists of various classes, and there are sufficiently notable differences of opinion. Still, all intuitionists believe that some moral truth, at least, is revealed to the individual by direct inspection (_intueor_), and that we must be content with such evidence and must not seek for proof. It may be maintained that our moral judgments--or some of them--are the result of "an immediate discernment of the natures of things by the understanding." and appeal may be made to the analogy furnished by mathematical truths. [Footnote: This appeal has been made by famous intuitionists from the seventeenth century to the nineteenth-- Cudworth, More, Locke, Clarke, Price, Whewell.] 91. VARIETIES OF INTUITIONISM.--Forms of intuitionism have been conveniently classified as Perceptional, Dogmatic and Philosophical. [Footnote: SIDGWICK, The Methods of Ethics, Book I, chapter viii, Sec 4.] To this nomenclature it may be objected that the term "dogmatic" carries with it a certain flavor of disapprobation, and predisposes one to the assumption of a critical attitude, while the term "philosophical" has the reverse suggestion, and smacks of special pleading. While admitting that there is something in the objection, I retain the convenient terms, merely warning the reader to be on his guard. (1) Perceptional Intuitionism falls back upon the analogy of perception in general. I seem to perceive by direct inspection that my blotter is green, and that my penholder is longer than my pencil. I do not seek for evidence; I do not have recourse to any chain of reasonings to establish the fact. And I am concerned here with facts, not with some general proposition applicable to many facts. Even so, I may maintain that, in specific situations, the rightness or wrongness of given courses of action may be perceived immediately. He who accepts the spontaneous deliverances of his conscience, when confronted with the necessity of making a decision, as revelations of moral truth, may be called a perceptional intuitionist. The deliverances must, however, be spontaneous and immediate, not the result of reasoning. If a man reasons, if he falls back upon general considerations, if he looks into the future and weighs the consequences of his act, and, as a result, decides what he ought to do, he is no longer a perceptional intuitionist.
