When we come to metaphysics, however, the opposite is true. Metaphysics has nothing to do with experience (as it is “beyond physics”). This means we cannot apply “categories” such as quantity and quality to metaphysics, because these are the framework of our knowledge of experience. Thus metaphysics excludes itself from the realm of synthetic a priori judgments and has no scientific basis. So if we take a metaphysical concept, such as God, we cannot make any scientific (or verifiable) statement about him, because any categories we might apply are relevant only to experience. Thus to talk of the existence (or nonexistence) of God is to misapply the categories.
