(1) It may be pointed out that such considerations as the above constitute an argument to prove the value of moral intuitions, and not one to prove the value of intuitionism as an ethical theory. That moral intuitions are indispensable may be freely admitted even by one who demurs to the doctrine that intuitionism in some one of its forms may be accepted as a satisfactory theory of morals.

(2) Perceptional Intuitionism, at least, cannot be regarded as embodying a rational theory or furnishing a science of any sort. Its one and only dogma must be that whatever actions reveal themselves to this man or that as right, are right, and there is no going behind the judgment of the individual.

Shall we say to men: "In order to know what is right and what is wrong in human conduct, we need only to listen to the dictates of conscience when the mind is calm and unruffled"? [Footnote: THOMAS REID, Essays on the Active Powers of Man, v, Sec 4.] As well say: "The right time is the time indicated by your watch, when you are not shaking it." If men are to keep appointments with each other, they must have some other standard of time than that carried by each man in his vest-pocket.

Perceptional Intuitionism ignores the fact that consciences may sometimes disagree, and that there may be a choice in consciences. The consistent perceptional intuitionist is, however, scarcely to be found, as has been said above; and we actually find those, some of whose utterances read as though the authors ought to be adherents of such a school, dwelling upon the desirability of the education of the conscience, i.e., upon the desirability of acquiring a capacity for having the right intuitions. In other words, they tell us to follow our noses—but to make sure that they point in the right direction. [Footnote: See THOMAS REID, Essays on the Active Powers of Man, iii, Part 3, Sec 8] In which case the determination of the right direction is not left to perceptional intuition.

(3) The Dogmatic Intuitionist has difficulties of his own with which to cope. It is not enough to possess a collection of valid and authoritative rules. The rules must be applied; there is room for the exercise of judgment and for the possibility of error. Error is not excluded even when the rule appears to be at only one or two removes from the individual instance; where the rule is one of great generality the problem of its application becomes correspondingly difficult. The interpretation of the rule is not given intuitively with the rule. This means that the rule must, in practice, be supplemented.

Always and everywhere, a straight line appears to be the shortest distance between two points. What is meant by shortness hardly seems to be legitimate matter for dispute. But the man convinced that he ought to pay his workman a fair wage, and that he ought to do his duty by his son, may be in no little perplexity when he attempts to define that fair wage or that parental duty. If he turns for advice to others, he will find that history and tradition, time, place and circumstance, very perceptibly color the advice they offer.

The application of the general rule is, hence, quite as important as the rule. There is no such thing as conduct in the abstract. Let us admit that benevolence is morally obligatory. How shall we be benevolent? Shall we follow Cicero, and give only that which costs us nothing? or shall we emulate St. Francis? The general rule may be a faultless skeleton, but it is, after all, only a skeleton, and it cannot walk of itself.

Again. The dogmatic intuitionist has quite a collection of rules by which he must judge of his actions. They are severally independent and authoritative. Suppose an act appears to be commanded by one rule and forbidden by another? Who shall decide between them? Prudence and benevolence may urge him in opposite directions. Benevolence and justice may not obviously be in harmony. The rule of veracity may seem, at times, to prescribe conduct which will entail much suffering on the part of the innocent. To what court of appeal can we refer the conflicts which may arise when ultimate authorities disagree? He who, in war time, can conscientiously shoot a sentry, but cannot conscientiously lie to him, may, later, have his misgivings, when the Golden Rule knocks at the gate of his mind.

(4) Nor does he leave all difficulties behind him, who abandons Dogmatic Intuitionism and takes refuge in Philosophical.

Kant's maxim needs a vast amount of interpretation. As it stands, it is little more than an empty formula. What I can wish to be the law of the universe must depend very much upon what I am. The lion and the lamb do not thirst for the same law. To the quarrelsome heroes of Walhalla a world of perpetual fighting and feasting must seem a very good world, in spite of knocks received as well as given. Kant's fundamental maxim scarcely appears to be a moral rule at all, unless we make it read: "Act on a maxim which a wise and good man can will to be a universal law." But how decide who is the wise and good man?
