If, however, a man does not strengthen the spiritual core of his being, merely asserting that the spiritual is the fruit of the physical, he will have a weak inner nature, he will be the victim of his inherited tendencies; they will work harmfully in him. No wonder then, that so-called inherited tendencies have such dreadful results; for people are first of all talked into belief of the powers of such tendencies and are deprived of what counteracts them. The belief in inherited tendencies is cultivated, and the spiritual conception of the world — the best weapon with which to fight them, — is taken away. First the power of the inherited tendencies is discovered, and by this means they become active. Not only is this a wrong insight, which arouses a life-destroying activity and takes the weapons of defence out of the hands of the sufferer, but it is the beginning of a theory based absolutely on a materialistic conception. Here a materialistic conception of the world begins to play a part which is in effect not only theoretically incorrect but immoral.
