The doctrine of right and wrong, is perpetually disputed, both by the pen and the sword: whereas the doctrine of lines, and figures, is not so; because men care not, in that subject, what be truth, as a thing that crosses no man’s ambition, profit or lust. For I doubt not, but if it had been a thing contrary to any man’s right of dominion, or to the interest of men that have dominion, that the three angles of a triangle, should be equal to two angles of a square; that doctrine should have been, if not disputed, yet by the burning of all books of geometry, suppressed, as far as he whom it concerned was able.
The great march of mental destruction will go on. Everything will be denied. Everything will become a creed. It is a reasonable position to deny the stones in the street; it will be a religious dogma to assert them. It is a rational thesis that we are all in a dream; it will be a mystical sanity to say that we are all awake. Fires will be kindled to testify that two and two make four. Swords will be drawn to prove that leaves are green in summer. We shall be left defending, not only the incredible virtues and sanities of human life, but something more incredible still, this huge impossible universe which stares us in the face. We shall fight for visible prodigies as if they were invisible. We shall look on the impossible grass and the skies with a strange courage. We shall be of those who have seen and yet have believed.
