Freedom is never a done deal, nor is it a fixed notion. - Cindy Milstein

The implication of mutual aid is that humans see themselves as part of nonhuman nature (though distinct from it in certain ways), needing to cooperate as much with the nonhuman natural world as with each other to survive and evolve. The ecological crisis is, in fact, a social crisis: humans believe they can dominate nonhuman nature because they believe it's natural to dominate other human beings. But mutual aid holds that humans, other animals, and plants all thrive best under forms of holistic cooperation—ecosystems. It suggests that people would be much more likely to live in harmony with each other and the nonhuman world—to be ecological—in a nonhierarchical society.

From the start, anarchism was an open political philosophy, always transforming itself in theory and practice. This, too, might be seen as part of its very definition. Anarchism has to remain dynamic if it truly aims to uncover new forms of domination and replace them with new forms of freedom, precisely because of the ever-present strain between personal and collective freedom. Self-organization necessitates everyone's participation, which requires being always amenable to new concerns and ideas. Yet when people are introduced to anarchism today, that openness, combined with a cultural propensity to forget the past, can make it seem a recent invention—without an elastic tradition, filled with debates, lessons, and experiments, to build on. Even worse, it can seem like a political praxis of "anything goes"—libertine without the libertarian—without regard for how one person's acts impact another person or community. It is critical to understand anarchism's past in order to understand its meaning, but also its problems and shortcomings as well as what we might want to retain and expand on. We study anarchist history to avoid repeating mistakes, but also to know we aren't alone on what has been and will likely be rocky, detour-filled "paths in utopia," to borrow the title of a Martin Buber book. Of course, it's generally helpful to understand historical contexts. Anarchism, for its part, is in large measure filled out and changed by its lived engagement in social struggle and visionary experimentation.

First and foremost, anarchism is a revolutionary political philosophy. That is, anarchism is thoroughly radical in the true sense of the word: to get at the root or origin of phenomena, and from there to make dramatic changes in the existing conditions. Anarchism aspires to fundamentally transform society, toward expansive notions of individual and social freedom.
