You must read the originator to practice something. You aren't a real capitalist if you haven't read Adam Smith and you aren't a real sadist if you haven't read the 120 days of Sodom. /s

Fr though, theory is great and more people should read it, but also we must burn our bookshelves to be free as it were. Theory is just ideas, both vital to our ability to imagine and build a better world, but ultimately something that should be willing to build on, challenge, and eventually make even the most important thinkers academic.

So yeah read Marx, Proudhon, Kropotkin, Stirner, Goldman, Lenin, Mao, Huey Newton, Angela Davis, Graeber… but not like how a Christian would read the Bible. Read them as one reads philosophers (and a biologist and anthropologist who also did philosophy). Read them critically and see what they got right, ask what they might have gotten wrong and why. Ask what you can learn from their ideas and the effects of different people's approaches to building on their ideas. When we treat them as secular prophets we do a disservice to them, ourselves, and those who will come after us.

Also like, do more than just read them. You actually have to try to meet people where they are. Talk about the ideas in ways that people are receptive to then eventually drop in where you got them. Convince ordinary people about this stuff as you organize to make more of it happen. Not through smugness but by sympathizing with their actual problems and building a dialog. Practice what you preach, both because it enhances credibility and is the right thing to do, but also because what we on the left preach is difficult to do and we need the practice.

That's why I have the kickflip-gibson function included in most of my publications. It notes the correlations (usually positive) between coolness l the quantity of kickflips, and quality of the air guitar solos you have during said kickflip. And the graph looks like Howard the Duck's duck girlfriend's bobs.

Most leftist books are complicated and boring, this one is simpler and more engaging. Maybe give it a try before tackling the dry tomes.

Berkman's work explains anarchist philosophy in terms that uninitiated readers can understand. The book's chapters are brief, and many of them begin with questions (e.g., "Is Anarchism Violence?", "Will Communist Anarchism Work?"). A number of the ideas he discusses are similar to those proposed in The Conquest of Bread by Peter Kropotkin, whom Berkman cites throughout. Berkman avoids the sort of jargon and technical language that is often used by political writers in favour of plain language. As he writes in his foreword:

Anarchist books, with few exceptions, are not accessible to the understanding of the average reader. It is the common failing of most works dealing with social questions that they are written on the assumption that the reader is already familiar to a considerable extent with the subject, which is generally not the case at all. As a result there are very few books treating of social problems in a sufficiently simple and intelligible manner. For the above reason I consider a restatement of the Anarchist position very much needed at this time—a restatement in the plainest and clearest terms which can be understood by every one. That is, an ABC of Anarchism.[11]
