If someone told you that they could prove that God exists simply because something - anything! - exists, would you believe them?
Probably not. But the Persian and Muslim philosopher, physician, and polymath Avicenna (980–1037) would. He argued that God’s existence can be established from the mere fact that anything exists at all.
This essay presents and explains what’s called Avicenna’s ‘proof’ for the existence of God. It is likely the most influential argument in the history of philosophy in the Islamic world.
