Every failure is a step to success. Every detection of what is false directs us towards what is true: every trial exhausts some tempting form of error. Not only so; but scarcely any attempt is entirely a failure; scarcely any theory, the result of steady thought, is altogether false; no tempting form of Error is without some latent charm derived from Truth.
William Whewell (1852). “Lectures on the History of Moral Philosophy in England”, p.101, London : J.W. Parker ; Cambridge : J. Deighton
