Biography
Denis Diderot was the indefatigable engine of the Enlightenment, a writer whose greatest work was editing the work of others. Born in Langres, France, in 1713, he initially enraged authorities with early philosophical writings that questioned orthodox religion, resulting in a brief imprisonment. His life's mission crystallized when he took over a failing translation project and turned it into the Encyclopédie, a 28-volume subversion disguised as a reference work. For over twenty years, Diderot recruited, cajoled, and edited contributions from the leading minds of Europe, weaving radical critiques of church, state, and social hierarchy into articles about crafts, sciences, and arts. He championed reason, empirical evidence, and human progress, often skirting censorship with wit and subterfuge. Beyond the Encyclopédie, he was a pioneering art critic, a novelist who explored psychological realism in 'Jacques the Fatalist,' and a playwright whose ideas on acting still resonate. He died in 1784, just five years before the revolution his ideas helped inspire.
