This work did not exactly match with my expectations, because I started off with a bit unconscious of how the main ideas and scopes (which I was instead quite aware of) would be developed. Main ideas which are, anyway, the most comprehensible message of the book: human society, or better human societies, must be rebuilt from scratch, beginning with a change in their premises, especially ethical and rational ones, which should enlighten and invest the relationship between humans, but also between human kind and nature - ethics and reason which invest, according to the Bookchinian philosophy of nature - which, from what I've caught, is a sort of reprisal of Aristotelian metaphysics, in light of some thesis brought upon recently by contemporary biology and philosophy of biology - also any relationship between other organic organism and the inorganic matter as a whole subjective entity, which ignores the antagonisms the human civilization was built on.
It is exactly this argument that ends up being obscure to me, to the extent that I think I've missed some points here and sincerely found myself all worn out in the effort - of course, being this an opus with more than 500 pages, very thick in content, with (apparently) many steps, leaps and deviations from the main argument of, say, a chapter, to some kind of abstract clarification, redundant examples or digressions. I must admit and denounce myself to be absolutely ignorant at the moment about anarchism, communalism and political theory regarding these views, so I guess it's pretty physiological that I lose the thread sometimes, but gosh: Bookchin made it so easy to feel lost on. Which is, genuinely, a shame, because the topics and the implications themselves, the irreducibly and uncompromisingly ethical stand of conceiving ourselves active part of the nature and our communities as well, are precious to me, and that's the take home message I've acquainted. Many specific arguments have been inspiring to me and require me to look more into them in further readings (from Bookchin himself or other thinkers): the dialectic of antagonism between nature and humanity and between humans as a requisite for the establishment of hierarchy, the epistemology of domination which is introjeced in our psyche, the distinction between government and management, the refusal of the marxian theory of abstract labour, the call for an aestheticized life experience and for a freedom of (rational) choice not in the realm of necessity within a society that has monopolized the concept of scarcity to the interest of the elites.
I'm sure I will dwell on this work again in a time to come - for now I think I need to build a larger conceptual framework regarding philosophy to grasp the power in this huge opus. I'm still glad I've tried.
