I really gotta go to bed.
Did you even glance at the link I posted?
No?
1.
No person may initiate or threaten to initiate the use of coercive physical force.
2.
Libertarianism does not concern itself with morality. To the contrary, libertarianism is probably best understood as being inherently non-judgmental: it intentionally rejects the making of moral judgments. Whereas a given libertarian may have a code of ethics - while he or she may have an understanding of good versus evil - libertarianism itself has no code of ethics and refuses ever to have one.
3.
Rather than aligning itself with any particular moral philosophy or code of ethics, libertarianism focusses on what it conceives of as justice. The belief underlying the libertarian's attachment to the Non-Aggression Axiom is that:
No injustice is done to a person against whom the Non-Aggression Axiom has not been violated.
Even if, under some code of ethics, a certain sort of conduct is evil, that conduct is not unjust from a libertarian point of view provided that the conduct did not involve the initiation of the coercive use of physical force.
4. Libertarianism sees the achievement and preservation of liberty as its ultimate goal. The means by which it aims to achieve its goal is by defending against injustice: by acting in self-defence when there is a violation of the Non-Aggression Axiom. Accordingly, the libertarian view equates liberty with the absence of injustice.
Now, I really am off to the sack.
