V. The Activity of Knowing the World

The correctness of critical idealism is one thing; the power of its proofs to convince in another. How matters stand with respect to the former will be shown later in the course of our considerations. But the power of its proof to convince is nil. If someone builds a house, and with the addition of the second floor, the ground floor collapses, the second floor falls along with it. Naive realism and critical idealism relate to each other as this ground floor to the second floor.
