What was said

… That's the anti-Semitism is a Jew's nightmare. Um, PJ. Prudhomme, I will end here. PJ. Prudhomme, uh, who actually came up with the word anarchism to describe his movement. I always liked him.

What we found

Supports. Harcourt's essay states that Proudhon famously exclaimed 'Property is theft!' in response to the question he posed in his 1840 book What Is Property?.[1]

Supports. Britannica says Proudhon famously declared 'Property is theft!' in his 1840 work, and Psychology Today describes Proudhon as the French politician who coined the phrase.[2][3]

Supports. Wikipedia identifies 'property is theft!' as Proudhon's best-known assertion, from his 1840 first major work, and the Vancouver Public Library and Molinari sources likewise credit him with the phrase.[4][5][6]

Context. An art and popular culture entry calls the slogan coined by Proudhon but notes a similar phrasing appearing in the Marquis de Sade's 1797 text, a nuance about earlier antecedents rather than a contradiction of the attribution.[7]
