Constant dripping hollows out a stone.
Forbear to spew out reason from your mind, but rather ponder everything with keen judgment; and if it seems true, own yourself vanquished, but, if it is false, gird up your loins to fight.
Gently touching with the charm of poetry.
Nothing comes from nothing.
If God can do anything he can make a stone so heavy that even he can't lift it. Then there is something God cannot do, he cannot lift the stone. Therefore God does not exist.
