Étienne Noël

Étienne Noël (29 September 1581 – 16 October 1659) was a Jesuit priest and natural philosopher. He was a teacher of René Descartes and is best known for clashing with Blaise Pascal on the idea of vacuum.

Noël was born in Bassigny and joined the Society of Jesus at Verdun in 1599. He then became a teacher at Rouen in 1605 and in 1606 at the college of La Flèche. René Descartes was a student here from 1607 to 1614 and Noël taught philosophy here. In 1646 he became rector at the College de Clermont in Paris. While here he published Aphorismi physici (1646) and Sol flamma (1646) and sent copies of it to Descartes. He was a follower of Aristotelian physics. In 1646 Pascal conducted experiments along with Evangelista Torricelli and published Expériences nouvelles touchant le vice (1647) in which he considered what the region above the mercury column was made of. Pascal suggested that it was a vacuum, which Noël opposed using the Aristotelian concept and suggested that it was filled with a part of air that could pass through the pores in glass. Descartes also suggested that some other form of matter existed. Noël published Le Plein du Vuide in response in 1648. Pascal responded to this initially in a letter to Jacques Le Pailleur and later directly to Noël. Pascal noted that it was not enough for a hypothesis to be true based on its consequences but also by whether it leads to contradictions. The debate was followed up by the Puy de Dôme experiment^[1] on September 19, 1648.^[2]^[3]^[4]
