Agorism
Born Samuel Edward Konkin III (July 8, 1947 - February 23, 2004) and nicknamed SEK3, Konkin was the father of Agorism and the writer of the New Libertarian Manifesto.
For Konkin, Agorism meant the consistent application of libertarian principles to strategy and tactics. Aside from other contributions to economic theory, the formal theory of Agorism remains SEK3's greatest accomplishment as a philosopher. The following introduction is from his book, An Agorist Primer.
The study of human action (praxeology) produced some repeatable observations deserving the title of scientific law. The area of human action dealing with exchanges between acting humans (catallactics) covers the same area of thought that economics is supposed to cover, but often with very different conclusions.
This kind of economics (sometimes called Austrian economics) was used by speculators such as Harry Browne and Doug Casey for investing in hard-money instruments, beating taxes, and surviving when society around them is operating on unreason and folly. It is that potent, a tool for survival amidst gloom and doom.
However, it can be more. By applying this economic understanding to all human action regardless of the wishes, whims, fears, and spite of the most powerful agency in society — the State (coercive government) — a new field of theory dealing only with practical action emerges: Counter-Economics.
Finally, when libertarian theory meets Counter-Economics, what comes out — in strict consistency, both external and internal — is Agorism. This is still another definition. And this is the definition with which I feel most comfortable, the one that the thieves of the intellect find hardest to pervert or steal:
Agorism is the consistent integration of libertarian theory with counter-economic practice; an agorist is one who acts consistently for freedom and in freedom.
