because it happened to find the church corrupt; it is a reformation essentially, in that every individual must reinterpret the Bible and the practices of the church in his own spirit. If he accepted them without renewing them in the light of his personal religious experience, he would never have what Protestantism thinks living religion. German philosophy has inherited this characteristic; it is not a cumulative science that can be transmitted ready made. It is essentially a reform, a revision of traditional knowledge, which each neophyte must make for himself, under pain of rendering only lip-service to transcendental truth, and remaining at heart unregenerate. His chief business is to be converted; he must refute for himself the natural views with which he and all other men have begun life. And still these views—like the temptations of Satan—inevitably form themselves afresh in each generation, and even in the philosopher, between one spell of introspective thought and another, so that he always has to recapitulate his saving arguments from the beginning. Each new idealist in each of his books, often in every lecture and every chapter, must run back to refute again the same homely opponents—materialism, naturalism, dualism, or whatever he may call them. Dead as each day he declares these foes to be, he has to fight them again in his own soul on the morrow.
