"I was lucky to hear the economist John Maynard Keynes, a few years before his death, give a lecture about the physicist Isaac Newton. Keynes was at that time himself a legendary figure, gravely ill and carrying a heavy responsibility as economic adviser to Winston Churchill. He had snatched a few hours from his official duties to pursue his hobby of studying Newton's unpublished manuscripts. Newton had kept his early writings hidden away until the end of his life in a big box, where they remained until quite recently. Keynes was speaking in the same old building where Newton had lived and worked 270 years earlier. In an ancient, dark, cold room, draped with wartime blackout curtains, a small audience crowded around the patch of light under which the exhausted figure of Keynes was huddled. He spoke with passionate intensity, made even more impressive by the pallor of his face and the gloom of the surroundings."
