What we don't understand we don't possess.
Yet here I stand poor fool what more, not one wit wiser than before.
I am certain that I have been here as I am now a thousand times before, and I hope to return a thousand times.
We are never deceived; we deceive ourselves.
In politics people throw themselves, as on a sickbed, from one side to the other in the belief they will lie more comfortably.
That we understand something perfectly, that we accomplish something better than anyone else around us, that is what matters.
