G.k. Chesterton said this quote

The word 'heresy' not only means no longer being wrong; it practically means being clear-headed and courageous. The word 'orthodoxy' not only no longer means being right; it practically means being wrong. All this can mean one thing, and one thing only. It means that people care less for whether they are philosophically right. For obviously a man ought to confess himself crazy before he confesses himself heretical.
