The futility and unwisdom of utter reliance upon feelings, unchecked by reason, was tragically evidenced by the sad case of Nijinsky, the famous Russian dancer, who after delighting audiences in the world's chief capitals became insane and for more than twenty years had to withdraw from his artistic career and pass most of his days in a sanatorium. Nijinsky kept a diary in the early days of his illness, in which we find sentences like the following: "I am God. I am God. I am God." Throughout those pages Nijinsky insists on feeling rather than thinking as a source of wisdom, and feeling he defines as "intuitions, proceeding from the unconscious." The man who claimed to be God was, however, unable to fulfil himself as a human being. Why? Because he was really unbalanced for he rejected utterly the claims of Reason, and he denounced "mental" people as being "dead."
