Much of Jewish Philosophy Turned away from the propositions of Theological Realism that asserted God`s Metaphysical Reality, Eternality, and Goodness after Kant. In this paper I argue that we must reevaluate the post-Kantian turn away from metaphysics, the eternal, etc in Jewish Existentialism and Phenomenology and Naturalism. I attempt to argue for a return to central notions of Jewish Theological Realism with a focus on the notion of God`s eternality.
