subject and predicate
‘three thousand years of important error’
“In January, 1955, I gave a lecture at the British Academy on J. S. Mill, which I had considerable difficulty in composing. I had already spoken so often about Mill. But the speech had one phrase that I cherish: in speaking about the fact that propositions have a subject and a predicate, I said it had led to ‘three thousand years of important error’. And the speech was acclaimed in a most gratifying manner. The audience rose, thumped and clapped.”
