Matthew Sands invited me to discussion for his project Nations of Sanity; we talked about voluntarism, anarcho-capitalism, non-aggression principle, intelectual property and voluntary slavery. It was quite theoretical debate; maybe because of those topics but mainly because we both obvisouly like it! I hope you will enjoy it despite my not so fluent English. – Matthew Sands; voluntarist; founder of Nations of Sanity project – Urza (www.urza.cz); author of the first Czech book on anarcho-capitalism; founder of the Free Haven project; co-founder and head of Czech Ludwig von Mises Institute; associate of Students for Liberty; member of Freedom to Learn committee
