In his honor, a quote from 1942's The Conquest of Time:
It did indeed seem to Ovid as though Time had swallowed many things so that they were altogether forgotten. But now Time swallows with less assurance, looks doubtful, stops eating, and turns green. Not only do events go on record, and keep on record, but Time begins to disgorge. Every year we win back more of the past...
And two from his 1920 work The Outline of History:
Human History becomes more and more a race between education and catastrophe.
Our true nationality is mankind.
