Anarchism is not like obscenity. You wont always know it when you see it. The Oxford Companion to Philosophy explains it like so: "There is no single defining position that all anarchists hold, and those considered anarchists at best share a certain family resemblance." Theres individualist anarchism, socialist anarchism, collectivist anarchism, feminist anarchism, green anarchism, and quite a few more. Then theres someone like Jennifer Silverman, who wrote a book called My Baby Rides the Short Bus: The Unabashedly Human Experience of Raising Kids with Special Needs. Is she an anarchist? We dont know. But she is a featured speaker at the Bay Area Anarchist Book Fair, so she might be. Or her book might be. We dont know. Anarchism is not a subject that can be neatly labeled and stuck on a shelf, obviously. Unlike books, which can, and there are many, many fine books and publishers at the fair, on the 15th year of the event. Yes, Ward Churchill is speaking. And so are Roxanne Dunbar-Ortiz and Andrej Grubacic, who pay tribute to the late Howard Zinn. Lierre Keith appears with her controversial book The Vegetarian Myth, which tweaks veganism. And theres the excellent-looking panel discussion The Revolutionary Legacy of John Brown with Terry Bisson and William Crossman. One of the biggest treats, wherever you fall on the anarcho-spectrum, is the lecture The Politics of Science by Kim Stanley Robinson, award-winning science fiction writer and anarchist?
