The peculiar functions of the physical brain are therefore no more entitled to be considered as an immortal entity, or as any necessary part or function of an immortal entity, than are the physical functions of deglutition or digestion, or the physical power of pedal locomotion. It is not for man to question the wisdom of God in so ordaining the relations of the soul to the body as to subordinate the eternal to the perishable. But it is man's duty so to exercise his powers of induction as to ascertain those relations; and, having done so according to his best lights, so to order his conduct as to do his whole duty to himself and his Creator. As we find those relations exist, the whole responsibility rests upon the objective man. He is a free moral agent, and has it in his power to train his soul for weal or woe, for this life and for eternity. It is of the relations which exist between objective and subjective man in this life that I propose to offer a few practical suggestions at this time. I have already shown that the normal functions of the subjective mind are apparently limited to the preservation of human life and the perpetuation of the human race. These functions are manifested in what are known as instincts. The first is the instinct of self-preservation; the second is the instinct of reproduction; and the third pertains to the preservation of the offspring. In the last may be included the instinctive desire to preserve human life generally. Outside of these limits all phenomenal subjective mental activity appears to be abnormal. I say _appears_ to be abnormal, for the reason that we have no means of judging, except from a consensus of facts. The facts which pertain to the subject can be found in the greatest abundance in spiritistic circles, for the reason that it is there that subjective activity is greatest in modern times. I venture to say that no one of the better class of spiritists will deny the fact that most professional mediums eventually become physical wrecks; many are overtaken by mental derangement, and some by a moral degradation too loathsome to be described. Few, if any, escape serious physical trouble. This, of itself, is sufficient evidence of abnormality, and should serve as a warning against the too frequent exercise of subjective power. The majority of spiritistic mediums are more or less afflicted with nervous disorders, and many of them are hysterical to the last degree. Most of them complain of extreme nervous exhaustion after a séance, and many require days to recover from the effects of a prolonged exercise of subjective power. It may be said that I mistake the cause for the effect; that is, that it may be only weak and nervous physical organisms that are capable of exercising subjective power. I am aware that the question is not free from difficulty, and that one is liable to fall into error in discussing a subject that is so little understood. The fact remains, nevertheless, that nervous disorders and
