This synthesis of the manifold of sensible intuition, which is possible and necessary a priori, can be called figurative (synthesis speciosa), as dis tinct from that which would be thought in the mere category in regard to the manifold of an intuition in general, and which is called combination of the understanding (synthesis intellectualis); both are transcenden tal, not merely because they themselves proceed a priori but also because they ground the possibility of other cognition a priori.
