Arnold Geulincx, Flemish philosopher and academic (died 1669)

Arnold Geulincx, 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.
