If we must not act save on a certainty, we ought not to act on religion, for it is not certain. But how many… — Blaise Pascal

If we must not act save on a certainty, we ought not to act on religion, for it is not certain. But how many things we do on an uncertainty, sea voyages, battles! I say then we must do nothing at all, for nothing is certain, and that there is more certainty in religion than there is as to whether we may see to-morrow; for it is not certain that we may see to-morrow, and it is certainly possible that we may not see it. We cannot say as much about religion. It is not certain that it is; but who will venture to say that it is certainly possible that it is not? Now when we work for to-morrow, and so on an uncertainty, we act reasonably; for we ought to work for an uncertainty according to the doctrine of chance which was demonstrated above.
