Kant comes up with an idea of intellectual intuition as a way to understand our limited faculty of reason as being dependent on external input. But that seems to be not exactly so. Rather it is possible that the intellect can recognize input that is not sensory input but rather of existing universals. This point of the Intuitionists [GE Moore, Prichard] seems quite true. To Kant intellectual intuition would have to create its own objects. But that doesn't seem to be so.
Hegel also criticizes this idea of Kant from a different angle. One is that this idea in itself points to the connection between Being and Reason. This connection Kant recoiled from. Hegel also used an argument that one can not recognize that something is finite unless he has gone beyond it and seen the point at which it stops. So to recognize intellect as being limited means one has already gone beyond it.
