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.
