And it is an explanation the possibility of which no evidence in favor of Materialism can possibly affect. For if, e. g., a man loses consciousness as soon as his brain is injured, it is clearly as good an explanation to say the injury to the brain destroyed the mechanism by which the manifestation of the consciousness was rendered possible, as to say that it destroyed the seat of consciousness. On the other hand, there are facts which the former theory suits far better. If, e. g., as sometimes happens, the man, after a time, more or less, recovers the faculties of which the injury to his brain had deprived him, and that not in consequence of a renewal of the injured part, but in consequence of the inhibited functions being performed by the vicarious action of other parts, the easiest explanation certainly is that, after a time, consciousness constitutes the remaining parts into a mechanism capable of acting as a substitute for the lost parts. And again, if the body is a mechanism for inhibiting consciousness, for preventing the full powers of the Ego from being prematurely actualized, it will be necessary to invert also
