 Metaphysics, then, properly includes an investigation into the cause of being—i.e., God, in whom the act of existing is subsistent. Some sympathetic scholars (e.g., Yves Floucat) have nevertheless questioned whether Maritain ultimately had a consistent, Thomistic view of what was the core of metaphysics (Floucat 1996). In any case, since Maritain holds that being is something that is grasped through intuition, one is not surprised to see that he will argue that one can attain knowledge of the existence of God not only through the Thomistic five ways, but also through intuition. (This is discussed in  section 3.4, ‘Natural Theology and Philosophy of Religion’, below.)
