Incurable.—The idealist is incorrigible: if he be thrown out of his Heaven, he makes himself a suitable ideal out of Hell. Disillusion him, and lo! he will embrace disillusionment with no less ardour than he recently embraced hope. In so far as his impulse belongs to the great incurable impulses of human nature, he can bring about tragic destinies and later become a subject for tragedy himself, for such tragedies as deal with the incurable, implacable, inevitable in the lot and character of man.
