Joseph Butler, Whole Works of Joseph Butler — Sermon 15 (1850)
“ If the make and constitution of man, the circumstances he is placed in, or the reason of things, affords the least hint or intimation that virtue is the law he is born under, scepticism itself should lead him to the most strict and inviolable practice of it: that he may not make a dreadful experiment of leaving the course of life marked out for him by nature, whatever that nature be, and entering paths of his own, of which he can know neither the dangers nor the end. For, though no danger be seen, yet darkness, ignorance, and blindness are no manner of security. ”
