 Following Weil’s philosophical development, her central concepts are addressed under five categories: social-political philosophy, epistemology, ethics, metaphysical and religious philosophy, and aesthetics. The periodization employed is as follows: 1925–1934 (early), 1935–1939 (middle), 1939–1943 (late). It is important to note that, given Weil’s rejection of systematicity and development of concepts, these categories and periods introduce a degree of artifice into her thought. The conclusion of this entry reports on her reception among the Continental and Anglo-American traditions of philosophy.
