Pascal

Blaise Pascal was the kind of mind that arrives once a century: a teenage geometrician who reinvented mathematics, a physicist who proved the atmosphere has weight, a writer whose satirical attacks on Jesuit casuistry still crackle with fury three centuries later. Yet his most famous work, the fragmentaryPensées, was written by a man in constant physical agony, obsessed with the eternal. John Tulloch's 19th-century biography traces this extraordinary arc: the precocious child of a mathematical household, the brilliant savant who befriended Descartes and Mersenne, the scientist who gambled with probability theory, and finally the devout Jansenist who retreated from the world to write about human weakness and divine mystery. The book illuminates how these apparently contradictory impulses lived in one person: the empiricist and the mystic, the rationalist and the penitent. Tulloch writes with Victorian admiration but also genuine psychological insight, painting Pascal as neither saint nor scientist but as something more interesting: a whole, tormented, brilliant human being.
