Pyotr Alexeyevich Kropotkin (1842-1921) was a geographer, a zoologist, and one of Russia's leading anarchists who advocated a communist society free from central government. Kropotkin's Law and Authority (1900) is a classic statement of anarchist thought. Considering prisons as “schools of crime”, he presents an anarchist critique of the law and the criminal-justice system. The text is much easier to understand than for example the works of Bakunin, and the argument is clearly stated for easy digestion. Kropotkin's argument is hard to dispute despite it being so simple.
