Anarchism is a political philosophy which considers the state undesirable, unnecessary, and harmful, and instead promotes a stateless society, or anarchy.[1][2] Anarchists seek to diminish or even abolish authority in the conduct of human relations,[3] but widely disagree on what additional criteria are essential to anarchism. According to The Oxford Companion to Philosophy, "there is no single defining position that all anarchists hold, and those considered anarchists at best share a certain family resemblance."[4]
