I like Kant a lot, and I think his questions were good, but most people did not accept his answers. That left room for immediate non intuitive knowledge of Fries and Leonard Nelson. But even Reid accepted the old world view that our mind is form without matter was not really the best approach. The questions brought up by Descartes,and Berkeley he did not really answer except to say that common sense shows our we our we do have knowledge of the objective world.
