Simone Weil  (1909 – 1943) was a French philosopher, mystic, and political activist.

After her graduation from formal education, Weil became a teacher. She taught intermittently throughout the 1930s, taking several breaks due to poor health and to devote herself to political activism, work that would see her assisting in the trade union movement, taking the side of the Anarchists known as the Durruti Column in the Spanish Civil War, and spending more than a year working as a labourer, mostly in auto factories, so she could better understand the working class.

Taking a path that was unusual among twentieth-century left-leaning intellectuals, she became more religious and inclined towards mysticism as her life progressed. Weil wrote throughout her life, though most of her writings did not attract much attention until after her death.
