Again, Christianity exists not merely as a matter of history. It exists also as a fact in living consciousness. It is the function of psychology to investigate that consciousness. We must say that, accurately speaking, there is no such thing as Christian philosophy. There are philosophies, good or bad, current or obsolete. These are Christian only in being applied to the history of Christianity and the content of the Christian consciousness. There is, strictly speaking, no such thing as Christian consciousness. There is the human consciousness, operating with and operated upon by the impulse of Christianity. It is the great human experience from which we single out for investigation that part which is concerned with religion, and call that the religious experience. It is essential, therefore, that those general investigations of human consciousness and experience, as such, which are being carried on all about us should be reckoned with, if our Christian life and thought are not altogether to fall out of touch with advancing knowledge. For this reason we have misgiving about the position of some followers of Ritschl. Their opinion, pushed to the limit, seems to mean that we have nothing to do with philosophy, or with the advance of science. Religion is a feeling of which he alone who possesses it can give account. He alone who has it can appreciate such an account when given. We acknowledge that religion is in part a feeling. But that feeling must have rational justification. It must also have rational guidance if it is to be saved from degenerating into fanaticism.
