For Plato, the daemonic is a sensibility that brings individuals into contact with divine knowledge; Socrates was also inspired by a 'divine voice' known as his 'daimonion.' Goethe was introduced to this ancient concept by Hamann and Herder, who associated it with the aesthetic category of genius. This book shows how the young Goethe depicted the idea of daemonic genius in works of the Storm and Stress period, before exploring the daemonic in a series of later poetic and autobiographical works. Reading Goethe's works on the daemonic through theorists such as Lukács, Benjamin, Gadamer, Adorno, and Blumenberg, Nicholls contends that they contain arguments concerning reason, nature, and subjectivity that are central to both European Romanticism and the Enlightenment.
