Thomas Nail argues convincingly and systematically that Lucretius was not an atomist, but a thinker of kinetic flux.In doing so, he completely overthrows the interpretive foundations of modern scientific materialism, whose philosophical origins lie in the atomic reading of Lucretius’ immensely influential book De Rerum Natura.This means that Lucretius was not the revolutionary harbinger of modern science as Greenblatt and others have argued; he was its greatest victim.Nail re-reads De Rerum Natura to offer us a new Lucretius – a Lucretius for today.
