Of what a state? and individual? or the actual philosophy behind it? I've already answered all of those. I linked you to an easy to understand wikipedia page to make it simple for you. If you chose not to read it, that's not my problem. For the state portion, one's never existed. Only communities.
because an anarchist state cannot exist.
you cannot claim that anarchy has never been tried, it existed for some time after the fall of the Pax Romana and before the rise of the european aristocratic dynasties.
it was what we call the Dark Ages. it was not fun times.
what i really wonder is why are you so averse to admitting you are a marxist?
being a marxist is not a crime. it's not even a social faux pas. theres lots of avowed marxists, and many are well respected thinkers, but those are generally COMMUNISTS who invite people to join their Utopia, not Socialists who try to compel everyone to submit to their Dystopia.
Socialism in all it's flavours, from democratic socialism in western europe to the depths of Pol Pot's madness are based on the simple principle that the apparatchiks know better than we do, and we just dont recognize their Greatness, even when we have it thrust upon us.
Why cant you simply tell us what you believe without resorting to contradictory wikipages which are really just nonsense, and own your beliefs?
since you have already implied that too much capitalism and freedom in the market is detrimental to your ideal society, exactly how much freedom are we to be allowed if you are installed as the Anarchist-in-Chief?
what form would governance take under your ideal society?
how would you ensure that malefactors and Counter-Revolutionaries and Reactionaries dont abuse the proletariat?
how would you equalize the distribution of wealth, considering the Bourgeois will not likely surrender their stuff willingly?
how would you ensure the smooth operation of industry agriculture and transportation of goods from the "Means of Production" to the hands of the proletariat?
how would you deal with any dissenters who say we need more freedom in our markets and associations than you permit?
and thats just the start.
