Compare and contrast the views of Thomas Hobbes and George Berkeley on Substance?

Thomas Hobbes believed that substance is incorporeal. Hobbes argued that there are no incorporeal substances, and that all things, including human thoughts, are corporeal, matter in motion.

On the other hand, Geroge Berkeley denied the existence of material substance but he felt that you could not deny the existence of physical objects such as Apples or mountains. Things that he could see with his eyes and touch with his hands existed.
