Siger of Brabant (Sigerus, Sighier, Sigieri or Sygerius de Brabantia; c. 1240 – before 10 November 1284) was a 13th-century philosopher from the southern Low Countries who was an important proponent of Averroism. He was considered a radical by the conservative members of the Roman Catholic Church, but it is suggested that he played as important a role as his contemporary Thomas Aquinas in the shaping of Western attitudes towards faith and reason.
