In a political context, freedom has only one meaning -- freedom from the initiation of force by other men.
Only by the initiation of force can a man be: prevented from speaking, or robbed of his possessions, or brutally murdered. Only by the initiation of force can a man’s rights be violated. Only the initiation of force against a man can stop his mind, thus rendering it useless as a means of survival.
It is for this reason -- that force renders a man’s mind useless -- that every man has the right to self-defence -- the right to use force to retaliate against those who first start the use of force, but never may one morally initiate it.
The use of force, in and of itself, is not evil; but, to initiate (start) force is evil. To use force in retaliation -- in self- defence against those who initiate it -- is not a moral option, but a moral requirement. A moral man has nothing to gain when a man tries to kill him, but he has much to lose if he does not defend himself. For this reason it is right, just, and proper to use force in retaliation and self-defence.
