Nicholas of Autrecourt (French: Nicholas d'Autrécourt; Latin: Nicolaus de Autricuria or Nicolaus de Ultricuria; c. 1299, Autrecourt – 16 or 17 July 1369, Metz) was a French medieval philosopher and Scholastic theologian.
Nicholas founded his skeptical position on arguments that knowledge claims were not "reducible to the first principle," that is, that it was not contradictory to deny them.
[1] Whether Nicholas was committed to skepticism is unclear, but on 19 May 1346 his views were condemned by Pope Clement VI as heretical.
[1] In the 14th century, Nicholas of Autrecourt considered that matter, space, and time were all made up of indivisible atoms, points, and instants and that all generation and corruption took place by the rearrangement of material atoms.
Some fragments of the lost letters are quoted in the records of the condemnatory proceedings against Nicholas.
