Mamet's Faustus--like Marlowe's and Goethe's before him--is a philosopher whose life's work has been the pursuit of "the secret engine of the world." He is also the distracted father of a small, adoring son. Out of the clash between love and intellect and the fatal operation of Faustus' pride, Mamet fashions a work that is at once caustic and heart-wrenching and whose resplendent language marries metaphysics to conman's patter. A meditation on reason and folly, fathers and sons, and a breathtaking display of magic both literal and theatrical, Faustus is a triumph.
