136. KANT.—-It is impossible, in any brief compass, to treat of the many individual moralists, some of them men of genius and well worthy of our study, who offer us ethical systems characterized by differences of more or less importance. When we refer a man to this or that school and do no more, we say comparatively little about him, as has become evident in the preceding chapters. As we have seen, it has been necessary to class together those who differ rather widely in many of their opinions. Here, I shall devote a few pages to three men only, partly because of their prominence, and partly because it is instructive to call attention to the contrast between them in their fundamental positions. I shall begin with Kant.
Kant held that the human reason issues "categorial imperatives," that is to say, unconditional commands to act in certain ways. The motive for moral action must not be the desire for pleasure, but solely the desire to do right.
He makes his fundamental rule abstract and formal: "So act that you could wish your maxim to be universal law." As no man could wish to be himself neglected when in distress, this law compels him to be benevolent, and a new form of the fundamental rule is developed: "Treat humanity, in yourself or any other, as an end always, and never as a means." [Footnote: Fundamental Principles of the Metaphysic of Morals, Sec 2.]
Now Kant, although he maintains that it is not a man's duty to seek his own happiness—a thing which natural inclination would prompt him to do— by no means overlooks happiness altogether. He thinks that virtue and happiness together constitute the whole and perfect good desired by rational beings. The attainment of this good must be the supreme end of a will morally determined. [Footnote: Dialectic of the Pure Practical Reason, chapter ii.] We are morally bound to strive to be virtuous ourselves and to make others happy.
Still, each man's happiness means much to him; and Kant, convinced that virtue ought to be rewarded with happiness, holds that our world is a moral world, where God will reward the virtuous. If we do not assume such a world, he claims, moral laws are reduced to idle dreams. [Footnote: Ibid.]
Such utterances as the last may well lead the utilitarian to question whether Kant was quite whole-hearted in his doctrine of the unconditional commands of the practical reason of man. They appear to be not independent of all consideration of human happiness.
I shall not ask whether Kant was consistent. Great men, like lesser men, seldom are. But, in order that the contrast between his doctrine and those of the two writers whom I shall next discuss may be brought out clearly, I shall ask that the following points be kept well in mind:
(1) Kant was an out-and-out intuitionist. He goes directly to the practical reason of man for an enunciation of the moral law.
(2) Moral rules of lesser generality, such as those touching benevolence, justice and veracity, he traces to the practical reason, making them independent of all considerations of expediency. Thus he defends the body of moral truth accepted by so many of his fellow-moralists.
(3) His "practical reason" speaks directly to the individual. Kant looked within, not without. We may call him an ethical individualist. Socrates, when on trial for his life, listened for the voice of the divinity within him. He needed no other.
