Have we any reason to suppose that total self-knowledge, if it were given to us, would be for our good? Children and fools, we are told, should never look at half-done work; and we are not yet, I trust, even half-done. You and I wouldn’t, at all stages, think it wise to tell a pupil exactly what we thought of his quality. It is much more important that he should know what to do next.
