This book provides a concise biography and philosophical overview of Saint Augustine. Strathern's work traces Augustine's life, from his struggles with sexuality and his overbearing mother, through his spiritual crisis and conversion to Christianity, to his significant contributions to philosophy. The text highlights Augustine's synthesis of Christianity and Neoplatonism, his original ideas on time and subjective knowledge, and his influential works, including Confessions and The City of God. Furthermore, the book situates Augustine within the broader context of late antique philosophy, examining preceding schools of thought like Stoicism and Epicureanism, and his impact on subsequent medieval thinkers. A chronology of key philosophical dates and a selected bibliography are also included.
