A millennia 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, haunted by his leading role in the first use of atomic weapons, understood only one aspect of prudence. His longing not to do evil himself blinded him to the need to ward off the evil of others. This painfully knotted man hoped with one swipe of his moral sword to rid himself of the impossible tangle and to be clear and simple for once in his life. But being Oppenheimer could never be as easy as that. For Oppenheimer embodied two of the highest human types, the theoretical man described by Aristotle as god-like for living in the mind, among changeless truths, and the paragon of Machiavellian virtue, god-like in commanding the power of life and death over other men. No theoretical man before Oppenheimer had known such lordly power. In certain high moments he approached that Aristotelian theoretical purity which lives for the joys of knowing the world, whatever it might prove to be; in another light he thrilled at that Machiavellian power and its attendant renown; in contrary moods he reviled himself for the suffering he brought into the world, and ached to renounce his distinction and to be merely another man among men. 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. Oppenheimer’s agony tore him open from top to bottom.

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.

Oppenheimer was lamenting the subservience of science to innate human cruelty in an address to the American Philosophical Society: “We have made a thing, a most terrible weapon, that has altered abruptly and profoundly the nature of the world ... a thing that by all the standards of the world we grew up in is an evil thing. And by so doing ... we have raised again whether science is good for man.” This public admission of personal despair at the moral collapse of the modern world’s leading intellectual enterprise could not be more nakedly penitent.

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-gunfight 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 bomb makers 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.
