I do not demand any right; therefore I need not recognise any either. What I can get by force I get by force and what I do not get by force I have no right to, nor do I give myself airs; or consolation, with talk of my inprescriptable right...Entitled or unentitled - that does not concern me; if I am only powerful, I am empowered of myself, and need no other empowering or entitling.
Max Stirner, The ego and his own 1845 (English translation 1907)
quoted in George Woodcock Anarchism 1962
Is this the root of modern libertarian thinking? Is this all it has to offer?
