Camus may be called a philosophe in the sense in which Voltaire used to be one. This book bears ample testimony to the fact that he was at once a writer and a philosophe in the Voltairean sense. His intrepid search for Sophia, or Truth,leads him to the founding of the philosophy of the absurd as the basis of metaphysical enquiries. In that sense he personifies the proper response to the challenge posed to the raison d'etre of metaphysics by Hume and the later materialist thinkers.
