It is notoriously difficult to fix labels of merit in such a way that they do not come off. Are not reviews of current literature a perpetual illustration of the difficulty of judgment? “This great book,” “this worthless book,” the same book is called by both names. Praise and blame alike mean nothing. No, delightful as the pastime of measuring may be, it is the most futile of all occupations, and to submit to the decrees of the measurers the most servile of attitudes. So long as you write what you wish to write, that is all that matters; and whether it matters for ages or only for hours, nobody can say. But to sacrifice a hair of the head of your vision, a shade of its color, in deference to some Headmaster with a silver pot in his hand or to some professor with a measuring-rod up his sleeve, is the most abject treachery, and the sacrifice of wealth and chastity, which used to be said to be the greatest of human disasters, a mere flea-bite in comparison.
