Libertarianism and the Non-Aggression Principle
Quick fact
Libertarianism's non-aggression principle holds that initiating force is always morally wrong, but it is often misunderstood as absolute pacifism; in fact, it explicitly allows and even encourages self-defense.
Why this is interesting
Imagine a society where you can do anything you want—as long as you don't force someone else. That's the core dream of libertarianism, but where exactly does the line of 'force' lie?
