““Charles Kahn offers the following summary of how a new metaphysics takes shape in Islamic philosophy: 'My general view of the historical development is that existence in the modern sense becomes a central concept in philosophy only in the period when Greek ontology is radically revised in the light of a metaphysics of creation; that is to say, under the influence of biblical religion. As far as I can see, this development did not take place with Augustine or with the Greek Church Fathers, who remained under the sway of classical ontology. The new metaphysics seems to have taken shape in Islamic philosophy, in the form of a radical distinction between necessary and contingent existence: between the existence of God on the one hand, and that of the created world on the other.' The new metaphysics that takes shape in Islamic philosophy proves fateful for subsequent philosophy in various ways. What will interest us immediately below is how it plays a role in triggering a debate about how to conceive divine creation. What will be of implicit interest later in these replies is how a remarkably unvarnished version of this new metaphysics comes to be detached from its original theological context. The ensuing detheologized modal metaphysics remains in force in some quarters of analytic philosophy, even though it takes its point of departure from a topic (how to understand the act of divine creation) that is no longer of much interest to most analytic philosophers. For the new metaphysics introduces concepts and ways of thinking that, once divested of their theological garb, continually resurface in the history of philosophy up to the present day.””
