This book explores the metaphysical underpinnings of theories of human nature, personhood, and the self. The coverage of the work is broad in scope, moving from the Pre-Socratics to Postmodernism, critically assessing what transpired during the intervening 2500 year period, with a special focus on the contributions of the Aristotelian/Thomistic tradition of inquiry. The work is designed to meet the needs of a wide range of readers, from beginners to more advanced students.

This book assumes an interdisciplinary character, providing a window into the subtle relationship between faith and reason in early patristic thought and its relevance for forging the doctrine of creation ex nihilo. In so doing, it highlights the extent to which early Christian thinkers found a common ground with the Greek philosophical tradition.

This book addresses the mid-rank of the soul theme as it emerges in Plotinus and Augustine in the context of their respective interpretations of universal order. They both use the journey metaphor to describe the soul's progress through the turbulent "sea" of earthly existence.
