This book brings Maximus the Confessor’s logoi doctrine into dialogue with modern-day evolutionary biology. It explores the extent to which the logoi, as described by Maximus, exhibit features that are concordant with evolution before going on to consider more discordant aspects that cannot be ignored. The author addresses the curious resonance between the logoi and evolution in a systematic way through a close reading of primary textual material allied with a deep understanding of both the classical Darwinian and ‘extended’ evolutionary syntheses. The study joins with other Maximian interpreters in attesting to the incarnational and theophanic nature of the logoi, but seeks to extend this distinctively Eastern Christo-cosmology into the problematic territory of biological evolution, a territory historically dominated by Western scholarship. The book will be of interest to scholars of religion and science, as well as Patristics and the Eastern Orthodox theological traditions.
