Yes, "Das Kapital" is interesting. Marx was actually more of an economist than a politician. Unfortunately most of the translations are rather "heavy going" as was the literary style of the time (try reading a novel by Sir Walter Scott ) BTW did you know that Marx is buried in Highgate Cemetery London?
Yes it took me a few years of study to finish all three volumes (agh!). I read several biographies of Marx, wasn't three of his children buried there too?

A is not non-A. Without this assumption, we are mad.
Take Rand's "corollaries" to "A is A": "Existence exists" inconsistant with "A is A", however "Existence is existence" is consistant. What do we get? Nihil. What is god? "God is God". what is truth? "Truth is Truth", etc. Obviously "A" is and is not "A".

We never challenge or doubt our fundamental assumptions.
Like a computer, you must have some minimal bootstrap code,
without which you could not proceed.
Why can't we challenge axioms? That is the purpose of metaphysics!

Have you considered that the Taliban were probably the only anarchist regime in recent history?
Just because there was chaos doesn't equate to there being anarchism. Mind you, that is a common thought: anarchists want anarchy. The two words have similiar greek roots, but anarchists want anarchism or stateless socialism. There was authoritarianism in Afghanistan, in one form or another (e.g. classes, religious superiority, etc.) which is what anarchism is exactly against.
