Sometimes it seems as if Israelis and Palestinians have no clear identities without the conflict, without the "enemy", whose existence is necessary, perhaps vital, to their sense of self and community.
Especially since Ibn Sina, the deity was widely identified with wajib al-wujud, "that whose existence is necessary"; but, as a philosophical category, is "necessary existence" necessarily unique?
The focus of the argument is the thesis that, if there is a God, then God's existence is necessary.
Echoing Descartes, Mendelssohn maintains that demonstration of God's existence is necessary to certify the actual existence of things outside us.
But though the fact that something's existence is necessary for the existence of something else holds for certain properties (for example, the existence of children is necessary for someone to be a parent), it is doubtful that something's existence is necessary for something else's nonexistence per se, which is what is needed to support the argument that denies the contingency of the universe.
If being and existence are necessary properties, then some contingent property must be offered in place that can be used to explain the intuition that (7) might have been true.
And just as it is better to exist than not to exist, it is better to exist necessarily than just to exist contingently, therefore Wolff concludes that God's existence is necessary.
A second principle is the Aristotelian "impossibility of an ordered, actual infinity" which, with the first principle, guarantees that "there cannot be an infinite number of levels of being and that there must be one being whose existence is necessary in itself Avicenna's 'Necessary of Existence' (wajib al-wujud)", the Light of Lights (Walbridge 2000: 24 5; PI, 87.1 89.8).
For nothing outside of God, not even the eternal truths or immutable essences, necessitate that God act in one way or another, but rather, they are themselves eternal and immutable in virtue of the fact that God, whose existence is necessary and immutable, willed them in their essence and existence.
This argument, a version of which we discuss below, establishes belief in God by appeal to moral considerations specifically, by arguing that postulating God's existence is necessary for thinking of the highest practical good as possible, and thus rendering morality credible.
