It must be understood that I am not now discussing the relation of these creeds to truth; but, for the present, solely their relation to health. Later in the argument I hope to attack the question of objective verity; here I speak only of a phenomenon of psychology. I do not for the present attempt to prove to Haeckel that materialism is untrue, any more than I attempted to prove to the man who thought he was Christ that he was labouring under an error. I merely remark here on the fact that both cases have the same kind of completeness and the same kind of incompleteness. You can explain a man's detention at Hanwell by an indifferent public by saying that it is the crucifixion of a god of whom the world is not worthy. The explanation does explain. Similarly you may explain the order in the universe by saying that all things, even the souls of men, are leaves inevitably unfolding on an utterly unconscious tree--the blind destiny of matter. The explanation does explain, though not, of course, so completely as the madman's. But the point here is that the normal human mind not only objects to both, but feels to both the same objection. Its approximate statement is that if the man in Hanwell is the real God, he is not much of a god. And, similarly, if the cosmos of the materialist is the real cosmos, it is not much of a cosmos. The thing has shrunk. The deity is less divine than many men; and (according to Haeckel) the whole of life is something much more grey, narrow, and trivial than many separate aspects of it. The parts seem greater than the whole.
