Kant proposed that his work be tested in small increments, beginning with the basic assertions. The "Prolegomena" can be used as a general outline to be compared to the "Critique". He was not satisfied with certain parts of the "Critique" and suggested that the discussions in the "Prolegomena" be used to clarify those sections. The unsatisfactory parts were the deduction of the categories and the paralogisms of pure reason in the "Critique". If the "Critique" and the "Prolegomena" are studied and revised by a united effort by thinking people, then metaphysics may finally become scientific. In this way, metaphysical knowledge can be distinguished from false knowledge. Theology will also be benefited because it will become independent of mysticism and dogmatic speculation.
