"But the knowledg of our Passions in their very Seeds, the measuring well the Growth and Progress of Enthusiasm, and the judging rightly of its natural Force, and what command it has over our very Senses, may teach us to oppose more successfully those Delusions which come arm'd with the specious Pretext of moral Certainty, and Matter of Fact."
— Cooper, Anthony Ashley, third earl of Shaftesbury (1671-1713)
