Pierre-Joseph Proudhon was the first person to call himself an anarchist and the originator of the phrase 'property is theft'. A prolific writer and thinker of the 1800s, his political philosophy continues to be influential upon today's libertarian political stands. Considered to be more influential than Marx in his lifetime, his work tackles labour, property, law, machinery, democracy and class. This collection brings together a definitive selection of his writing, much of which has long been out of print.
