Chapter 4
Subjective And Objective Mind

Up to this point it has been necessary to lay the foundations of the science by the statement of highly abstract general principles which we have reached by purely metaphysical reasoning. We now pass on to the consideration of certain natural laws which have been established by a long series of experiments and observations, the full meaning and importance of which will become clear when we see their application to the general principles which have hitherto occupied our attention. The phenomena of hypnosis are now so fully recognized as established scientific facts that it is quite superfluous to discuss the question of their credibility. Two great medical schools have been founded upon them, and in some countries they have become the subject of special legislation. The question before us at the present day is, not as to the credibility of the facts, but as to the proper inferences to be drawn from them, and a correct apprehension of these inferences is one of the most valuable aids to the mental scientist, for it confirms the conclusions of purely a priori reasoning by an array of experimental instances which places the correctness of those conclusions beyond doubt.
