What a fellow Wilson is! If I could only throw the same enthusiasm into physiology that he does into psychology, I should become a Claude Bernard[17] at the least. His whole life and soul and energy work to one end. He drops to sleep collating his results of the past day, and he wakes to plan his researches for the coming one. And yet, outside the narrow circle who follow his proceedings, he gets so little credit for it. Physiology is a recognized science. If I add even a brick to the edifice, every one sees and applauds it. But Wilson is trying to dig the foundations for a science of the future. His work is underground and does not show. Yet he goes on uncomplainingly, corresponding with a hundred semi-maniacs in the hope of finding one reliable witness, sifting a hundred lies on the chance of gaining one little speck of truth, collating old books, devouring new ones, experimenting, lecturing, trying to light up in others the fiery interest which is consuming him. I am filled with wonder and admiration when I think of him, and yet, when he asks me to associate myself with his researches, I am compelled to tell him that, in their present state, they offer little attraction to a man who is devoted to exact science. If he could show me something positive and objective, I might then be tempted to approach the question from its physiological side. So long as half his subjects are tainted with charlatanry and the other half with hysteria we physiologists must content ourselves with the body and leave the mind to our descendants.
No doubt I am a materialist. Agatha says that I am a rank one. I tell her that is an excellent reason for shortening our engagement, since I am in such urgent need of her spirituality. And yet I may claim to be a curious example of the effect of education upon temperament, for by nature I am, unless I deceive myself, a highly psychic man. I was a nervous, sensitive boy, a dreamer, a somnambulist, full of impressions and intuitions. My black hair, my dark eyes, my thin, olive face, my tapering fingers, are all characteristic of my real temperament, and cause experts like Wilson to claim me as their own. But my brain is soaked with exact knowledge. I have trained myself to deal only with fact and with proof. Surmise and fancy have no place in my scheme of thought. Show me what I can see with my microscope, cut with my scalpel, weigh in my balance, and I will devote a lifetime to its investigation. But when you ask me to study feelings, impressions, suggestions, you ask me to do what is distasteful and even demoralizing. A departure from pure reason affects me like an evil smell or a musical discord.
