Each one of us, in his timidity, has a limit beyond which he is outraged. It is inevitable that he who by concentrated application has extended this limit for himself, should arouse the resentment of those who have accepted conventions which, since accepted by all, require no initiative of application. And this resentment generally takes the form of meaningless laughter or of criticism, if not persecution.
