"He" was Plato and his idealism was quite different from Kant's. Psychologial certainty is what we feel to be true. Real certainty is what we feel when we step in front of a speeding truck.

I betcha that some people are as psychologically certain that there is a God as I am really certain of what happens if I stepped in front of a speeding truck. How do we know that we are only psychologically certain of something and are not really certain of it?

Getting back to Socrates, I am certain that he was more concerned than Kant with establishing that no one possessed absolute truth. His method for establishing that is what led to his death.
