Post-civilized thought is based on three simple premises:
1 – This civilization is, from its foundation, unsustainable. It probably cannot be salvaged, and, what’s more, it would be undesirable to do so.
2 – It is neither possible, nor desirable, to return to a pre-civilized state of being.
3 – It is therefore desirable to imagine and enact a post-civilized culture.
I certainly don't agree with the whole thing but I do like its spirit: "We are for an ecologically-focused green anarchism and we are for mutual aid, free association, and self-determination."
