From William Lily’s Rudimenta Grammatices to Geoffrey Hinton’s neural networks, this essay traces five centuries of inquiry into language — from moral discipline to scientific method to artificial intelligence — and asks why linguistics, the study of language itself, never solved the question that machines finally answered.
Jean-Paul Sartre (1905–1980) turned the collapse of religious certainty into a demand for moral self-authorship. This essay sketches his life, clarifies his philosophy (“existence precedes essence”), traces the steps by which he reached his insights—from bleak fiction to public ethics—and considers possible misunderstandings that remain. It concludes with a sober appraisal: we need not act from anxiety or ideology; real action springs from the will to live.
