"By demonstrating the unusual 'light' of opacity, the clarity of darkness, and the shimmering of shadows in pre-Socratic philosophy, Spitzer destabilizes the common views on the beginning of the Western philosophical tradition, which mostly rely on the belief that this beginning coincides with the birth of light itself. Breaking Light opens new paths for our reading of ancient Greek philosophy and enables a criticism of the common idea that philosophical thought is committed solely to clarity." — Marcia Sá Cavalcante Schuback, Södertörn University
