"Now, to fuse these three propositions into one: suppose that I take a man, and, by removing the brain that enshrines all the errors and failures of his ancestors away back to the origin of the race, remove all sources of weakness in his future career. Suppose, that in place of the fallible intellect which I have removed, I endow him with an artificial intellect that operates with the certainty of universal laws. Suppose that I launch this superior being, who reasons truly, into the burly burly of his inferiors, who reason falsely, and await the inevitable result with the tranquillity of a philosopher. "Monsieur, you have my secret. That is precisely what I have done. In Moscow, where my friend Dr. Duchat had charge of the new institution of St. Vasili for hopeless idiots, I found a boy of eleven whom they called Stépan Borovitch. Since he was born, he had not seen, heard, spoken or thought. Nature had granted him, it was believed, a fraction of the sense of smell, and perhaps a fraction of the sense of taste, but of even this there was no positive ascertainment. Nature had walled in his soul most effectually. Occasional inarticulate murmurings, and an incessant knitting and kneading of the fingers were his only manifestations of energy. On bright days they would place him in a little rocking-chair, in some spot where the sun fell warm, and he would rock to and fro for hours, working his slender fingers and mumbling forth his satisfaction at the warmth in the plaintive and unvarying refrain of idiocy. The boy was thus situated when I first saw him.
