Necessary Existence
There are many views among philosophers about the existence of God and particularly the it being necessary existence or non necessary existence. ... The two versions of arguments or views in context of ontological arguments for the necessary existence of god are: first one is that God is the most perfect being. ... The second version says that existence is perfection, assuming that existence is positive property. And that it is legitimate subject of which existence would be predicated as a concept or an idea. ... Other have also argued the second argument which Avicenna is supporting, Kant and Hume are opposed to the argument, Kant says that “existence is not predicated” hence refuting the argument. Necessary existence has been one of the most prominent concept in Avicenna’s metaphysical writing as Parviz Morewegde says.
