Editing Early Islamic philosophy (section)

===Time===
While ancient Greek philosophers believed that the universe had an infinite past with no beginning, early [[Medieval philosophy|medieval philosophers]] and theologians developed the concept of the universe having a [[Temporal finitism|finite past]] with a beginning. This view was inspired by the [[creationism]] shared by [[Judaism]], [[Christianity]] and [[Islam]]. The [[Christian philosophy|Christian philosopher]] [[John Philoponus]] presented a detailed argument against the ancient Greek notion of an infinite past. Muslim and Arab Jewish philosophers like [[Al-Kindi]], [[Saadia Gaon]], and [[Al-Ghazali]] developed further arguments, with most falling into two broad categories: assertions of the "impossibility of the existence of an actual infinite" and of the "impossibility of completing an actual infinite by successive addition".<ref name=Craig>{{citation |title=Whitrow and Popper on the Impossibility of an Infinite Past |first=William Lane |last=Craig |journal=The British Journal for the Philosophy of Science |volume=30 |issue=2 |date=June 1979 |pages=165–70 [165–66] |doi=10.1093/bjps/30.2.165}}</ref>
