The author explores the differing forms of unity in the transcendental conditions for the synthesis of experience. His results shed light on Kant's understanding of synthesis. The three main chapters deal with the architectonic unity of philosophy (and every science), the identity of functions of the understanding that provide unity, and with the differing applications in the synthesis of intuition and judgment.
