From this opinion, however, Dr. Willett substantially dissents, basing his verdict on his close and continuous knowledge of the patient, and on certain frightful investigations and discoveries which he made toward the last. Those investigations and discoveries have left their mark upon him; so that his voice trembles when he tells them, and his hand trembles when he tries to write of them. Willett admits that the change of 1919–20 would ordinarily appear to mark the beginning of a progressive decadence which culminated in the horrible sad uncanny alienation of 1928, but believes from personal observation that a finer distinction must be made. Granting freely that the boy was always ill-balanced temperamentally, and prone to be unduly susceptible and enthusiastic in his responses to phenomena around him, he refuses to concede that the early alteration marked the actual passage from sanity to madness; crediting instead Ward's own statement that he had discovered or rediscovered something whose effect on human thought was likely to be marvellous and profound.
