Arnold Geulincx, Flemish philosopher and academic (d. 1669)
Arnold Geulincx (Dutch pronunciation: [ˈɣøːlɪŋks]; 31 January 1624 – November 1669), also known by his pseudonym Philaretus, was a Flemish philosopher, metaphysician, and logician. He was one of the followers of René Descartes who tried to work out more detailed versions of a generally Cartesian philosophy. Samuel Beckett cited Geulincx as a key influence and interlocutor because of Geulincx's emphasis on the powerlessness and ignorance of the human condition.
