“A millenarian fire burned in Oppenheimer’s spirit, fueled by his pride as a world-historical individual, by his fear that the natural force he loosed upon the world would escape all human control, and by a pure-hearted longing to ensure that his discovery of the devastation latent in the elemental substance of the world would serve concord rather than the ultimate discord, perpetual peace rather than permanent self-destruction.”

“Oppenheimer’s theorizing was so startlingly original — so far in advance of the corroborating observations and so far off the beaten track of astrophysical research — that his colleagues’ ignorance cost him the recognition he deserved.”

“The career of J. Robert Oppenheimer, the physicist who headed the Manhattan Project, draws such questions to a focus that resembles the bead of a laser-gunsight on a victim’s breastbone. It was Oppenheimer whom the public lionized as the brains behind the bomb; who agonized about the devastation his brilliance had helped to unleash; who hoped that the very destructiveness of the new “gadget,” as the bombmakers called their invention, might make war obsolete; and whose sometime Communist fellow-traveling and opposition to the development of the hydrogen bomb — a weapon a thousand times more powerful than the bombs that incinerated Hiroshima and Nagasaki — brought about his political disgrace and downfall, which of course have marked him in the eyes of some as all the more heroic, a visionary persecuted by warmongering McCarthyite troglodytes. His legacy, of course, is far more complicated.”

“Perhaps no theoretical man can be equal to such a burden: to feel knowledge as power when one’s mind reshapes the world irrevocably, to see the light of truth as the agent of some dark majesty, is not grace but ordeal.”
