Catholic Church Banned Infinitesimals from European Classrooms Taught by Jesuits
(p. C9) Mr. Alexander's narrative opens in the early 17th century, when Catholic Church administrators in Rome, following a campaign by Euclidean stalwart Christopher Clavius, banned the infinitesimal from the classrooms of Jesuit schools throughout Europe. Instructors' teachings and writings were monitored to enforce strict adherence to the classical Euclidean geometrical tradition. Mr. Alexander portrays the church's reactionary stance not as a huff over mathematical philosophy but as a desperate counterattack against existential threats: Euclid's rules-based structure offered the church a model with which it hoped to rein in a restive flock, roiled by economic and political currents and by an ascendant Protestantism. Martial metaphors abound in the author's telling: "war against disorder," "enemies of the infinitely small," "forces of hierarchy and order." This was no friendly debate.
