François Marie Charles Fourier (/ˈfʊəriˌeɪ, -iər/; French: [fuʁje]; 7 April 1772 – 10 October 1837) was a French philosopher and an influential early socialist thinker later associated with "utopian socialism". Some of Fourier's social and moral views, held to be radical in his lifetime, have become mainstream thinking in modern society.
