The contributions to this book offer a broad vision of the relationships that were established between Greek Philosophy and the Mystery Cults. The authors centre their attention on such thinkers as Plato, Aristotle, and the Stoic and the Neoplatonist philosophers, who used – and in some cases criticised – doctrinal elements from Mystery Cults, adapting them to their own thinking. Thus, the volume provides a new approach to some of the most renowned Greek philosophers, highlighting the influence that Mystery Cults, such as Orphism, Dionysianism, or the Eleusinian rites, had on the formation of fundamental aspects of their thinking. Given its interdisciplinary character, this book will appeal to a broad academic readership interested in the origin of Hellenic thinking and culture. It will be especially useful for those eager for a deeper approach to two fundamental domains that attract the attention of many Antiquity scholars: Greek philosophy and religion.
