Renowned for his contributions to the literary world, Johann Wolfgang von Goethe (1749-1832) believed his greatest accomplishments were in the fields of science and natural philosophy. In fact, Goethe predicted his scientific works would spark a revolution, eclipsing the theories of Newton and Enlightenment science. Astrida Orle Tantillo offers the first comprehensive study of Goethe's natural philosophy, analyzing his work in such disciplines as physics, botany, morphology, zoology, and meteorology. She investigates the principles behind his conception of a will-driven nature, and analyzes their significance for such philosophical issues as objectivity, scientific method, and the status of natural law in general. Tantillo also critically examines Goethe's attempts to challenge the basic tenets of Newtonian and Cartesian science and his efforts to found a new natural philosophy.
