Perhaps more important, I have a visceral knowledge that I can experience something personally, and be confident of it, and be completely wrong about it.

Eliot:

And last, the rending pain of re-enactment
Of all that you have done, and been; the shame
Of motives late revealed, and the awareness
Of things ill done and done to others' harm
Which once you took for exercise of virtue.
Then fools' approval stings, and honour stains.
