It is easy for smart people to see the mistakes of the dumb. But they can also fall into mistakes by being too smart. --It is like the parable of the tortoise and the hare. The swiftness of the tortoise was its own cause of being too slow. So in the Midrash we find the mother of Samuel the Prophet praying that her son should not be too smart nor too dumb. Philosophers have at the disadvantage of being too smart==as Kant himself pointed out in that when the mind ventures into areas of things in themselves self contradictions arise. and Kant applied that insight to the human personality--when a person thinks about things where reason by its very nature is incapable, these same people go nuts.
You can see this limitation in Hegel where his system does not recognize the limits of reason. [His system can be likened to PLOTINUS, HEGEL starts from the material world and by the dialectic rises to the Absolute Spirit. But his system ends with what Plotinus would call THE LOGOS. But plotinus did not stop there. There is something higher than logos, i.e. THE ONE.]
