A man’s volition is outside the power of other men. What the unalterable basic constituents are to nature, the attribute of a volitional consciousness is to the entity “man.” Nothing can force a man to think. Others may offer him incentives or impediments, rewards or punishments, they may destroy his brain by drugs or by the blow of a club, but they cannot order his mind to function: this is in his exclusive, sovereign power. Man is neither to be obeyed nor to be commanded.
