Now what I have myself tried to do is to be thoroughly modern in this sense. I hold that one should not only welcome the efforts of the man of science at his best to put the natural law on a positive and critical basis, but that one should strive to emulate him in one’s dealings with the human law; and so become a complete positivist. My main objection to the movement I am studying is that it has failed to produce complete positivists. Instead of facing honestly the emergency created by its break with the past the leaders of this movement have inclined to deny the duality of human nature, and then sought to dissimulate this mutilation of man under a mass of intellectual and emotional sophistry. The proper procedure in refuting these incomplete positivists is not to appeal to some dogma or outer authority but rather to turn against them their own principles. Thus Diderot, a notable example of the incomplete positivist and a chief source of naturalistic tendency, says that “everything is experimental in man.” Now the word experimental has somewhat narrowed in meaning since the time of Diderot. If one takes the saying to mean that everything in man is a matter of experience one should accept it unreservedly and then plant oneself firmly on the facts of experience that Diderot and other incomplete positivists have refused to recognize. The man who plants himself, not on outer authority but on experience, is an individualist. To be modern in the sense I have defined is not only to be positive and critical, but also--and this from the time of Petrarch--to be individualistic. The establishment of a sound type of individualism is indeed the specifically modern problem. It is right here that the failure of the incomplete positivist, the man who is positive only according to the natural law, is most conspicuous. What prevails in the region of the natural law is endless change and relativity; therefore the naturalistic positivist attacks all the traditional creeds and dogmas for the very reason that they aspire to fixity. Now all the ethical values of civilization have been associated with these fixed beliefs; and so it has come to pass that with their undermining by naturalism the ethical values themselves are in danger of being swept away in the everlasting flux. Because the individual who views life positively must give up unvarying creeds and dogmas “anterior, exterior, and superior” to himself, it has been assumed that he must also give up standards. For standards imply an element of oneness somewhere, with reference to which it is possible to measure the mere manifoldness and change. The naturalistic individualist, however, refuses to recognize any such element of oneness. His own private and personal self is to be the measure of all things and this measure itself, he adds, is constantly changing. But to stop at this stage is to be satisfied with the most dangerous of half-truths. Thus Bergson’s assertion that “life is a perpetual gushing forth of
