constitute the activities of an animal body no principles can be discerned other than those which govern the activities of inorganic matter. There can be no dispute as to the main physiological facts. No reactions between the material components of an animal body have been observed which in any way infringe the physical and chemical laws applying to the behavior of inorganic material. But this is a very different proposition from the doctrine that no additional principles can be involved. The two propositions are only identical on the supposition that the sort of physical principles involved are sufficient to determine definitely the particular activities of each physical body.
This is certainly not the case if we refer to principles such as the conservation of energy, and the chemical reactions. It is often assumed that even the one law of the conservation of energy determines without ambiguity the activities to which it applies. It is difficult to understand how such a baseless fiction could have arisen.
But the point to which I wish to draw attention is the mass of evidence lying outside the physiological method which is simply ignored im the prevalent scientific doctrine. The conduct of human affairs is entirely dominated by our recognition of foresight determining purpose, and purpose issuing in conduct. Almost every sentence we utter and every judgment we form, presuppose our unfailing experience of this element in life. The evidence is so overwhelming, the belief so unquestioning, the
