“An ignorant man, who is not fool enough to meddle with his clock, is however sufficiently confident to think he can safely take to pieces, and put together at his pleasure, a moral machine of another guise, importance and complexity, composed of far other wheels, and springs, and balances, and counteracting and co-operating powers. Men little think how immorally they act in rashly meddling with what they do not understand. Their delusive good intention is no sort of excuse for their presumption. They who truly mean well must be fearful of acting ill.”
