If degeneration is deeper, and ego-mania is stronger, the latter no longer assumes the comparatively innocent form of total absorption in poetic and artistic cooings, but manifests itself as an immorality, which may amount to moral madness. The tendency to commit actions injurious to himself or society is aroused now and then even in a sane man when some obnoxious desire demands gratification, but he has the will and the power to suppress it. The degenerate ego-maniac is too feeble of will to control his impulsions, and cannot determine his actions and thoughts by a regard to the welfare of society, because society is not at all represented in his consciousness. He is a solitary, and is insensible to the moral law framed for life in society, and not for the isolated individual. It is evident that for Robinson Crusoe the penal code did not exist. Alone on his island, having only Nature to deal with, it is obvious he could neither kill, steal, nor pillage in the sense of the penal code. He could only commit misdemeanours against himself. Want of insight and of self-control are the only immoralities possible to him. The ego-maniac is a mental Robinson Crusoe, who in his imagination lives alone on an island, and is at the same time a weak creature, powerless to govern himself. The universal moral law does not exist for him, and the only thing he may possibly see and avow, perhaps also regret a little, is that he sins against the moral law of the solitary, _i.e._, against the necessity of controlling instincts in so far as they are injurious to himself.
