 While (in some places at least) Plato connects the necessary character of the Forms to timelessness, in Aristotle the connection is between necessity and everlastingness. What is necessary is what exists at all times. What is contingent is what at some time is not. God, being necessary, is everlasting. It may be said that the everlasting is not bounded by time (though it is unbounded in a weaker sense than Plato ascribes to the Forms) in that what exists everlastingly cannot age (Physics 221b30). Philo of Alexandria is thought to be the first to ascribe timelessness to God, to the God of the Jewish Scriptures. In Plotinus (ca. 185–254) timelessness and life are for the first time identified. Nous is eternal and beyond time, enjoying duration without succession.
