No new thought, nothing of the nature of a finer turning or better expression of an old thought, not even a proper history of what has been previously thought on the subject: an IMPOSSIBLE literature, taking it all in all, unless one knows how to leaven it with some mischief. In effect, the old English vice called CANT, which is MORAL TARTUFFISM, has insinuated itself also into these moralists (whom one must certainly read with an eye to their motives if one MUST read them), concealed this time under the new form of the scientific spirit; moreover, there is not absent from them a secret struggle with the pangs of conscience, from which a race of former Puritans must naturally suffer, in all their scientific tinkering with morals.
