Greek Philosopher's view about Life-giving Efficient Cause

The issue of efficient cause is one of the important discussions which can be studied in ancient Greek philosophy. The present paper first examines the issue in the pre-Socrates philosophy and then in the philosophy of Plato and Aristotle. A number of the Greek philosophers believe only in the natural cause، that is، the matter of matters، whereas others are convinced of the existence of the unnatural non-life-giving efficient cause. They think that being does not come from non-being، so the universe is eternal and cannot have a life-giver. So، ancient Greek philosophers'' belief in being coming from non-being is contrary to the foundation of their thinking. Given the external aspect of their works، they do not believe in the mode of creation forwarded by the Abrahamic religions. Their god is، therefore، different from God in divine faiths.
