Man may therefore cease to be restrained, without, for that reason, becoming a free agent: in whatever manner he acts, he will act necessarily; according to motives by which he shall be determined. He may be compared to a heavy body, that finds itself arrested in its descent by any obstacle whatever: take away this obstacle, it will gravitate or continue to fall; but who shall say this dense body is free to fall or not? Is not its descent the necessary effect of its own specific gravity? The virtuous Socrates submitted to the laws of his country, although they were unjust; notwithstanding the doors of his gaol were left open to him he would not save himself; but in this he did not act as a free agent; the invisible chains of opinion, the secret love of decorum, the inward respect for the laws, even when they were iniquitous, the fear of tarnishing his glory, kept him in his prison: they were motives sufficiently powerful, with this enthusiast for virtue, to induce him to wait death with tranquillity; it was not in his power to save himself, because he could find no potential motive to bring him to depart, even for an instant, from those principles to which his mind was accustomed. Man, says he, frequently acts against his inclination, from whence he has falsely concluded he is a free agent; when he appears to act contrary to his inclination, he is determined to it by some motive sufficiently efficacious to vanquish this inclination. A sick man, with a view to his cure, arrives at conquering his repugnance to the most disgusting remedies: the fear of pain, the dread of death, then become necessary and intelligent motives; consequently, this sick man cannot be said, with truth, by any means, to act freely.
