not worked. I believe the reason why it does not work is, that it ignores some faintly discernible but growing tendencies in human nature which are not to be discerned without more sympathy than you appear to possess: no human being can be understood in the daylight of Reason alone; affection and Imagination are needed to transport us as it were into the heart of a fellow-creature, to enable us to realize him as we realize ourselves, and to treat him as we would ourselves be treated; faith also in the possibilities of humanity is a very powerful help not only towards discerning the best and noblest that men can do, but also towards developing their power of doing it. But in any case, whatever may be the reasons for its failure, your theory does not "work," and must therefore be given up.
"By 'failure,' I do not mean that your theory will prevent you from getting on and making your way in the world, but that it will prevent you from operating on yourself and on mankind, so that you and they may do the work which you are intended to do. You say the business of a student of men is to be critical. I say that such a student is a mere pedant, a book-philosopher: but the scientific student of men is he who knows how to 'work' them: and those who have in the true sense of the term 'worked' men, have not been of the critical temperament which you eulogize, but often quite uncritical, wondrously uncritical, but full of a fervent faith in a high ideal of humanity, and in a destiny that would ultimately conform humanity to its ideal. If you aim at exerting no social ennobling influence of this kind, if you are content, while leading the life of a man of the world, to abide, spiritually speaking, in the cave of a recluse, then keep on your present course. Criticize men dispassionately to your heart's content. Try to persuade yourself that you know them. But you will never succeed—you will never persuade
