This book brings together a selection of Kevin Corrigan's works published over the course of some 27 years. Its predominant theme is the encounter with otherness in ancient, medieval and modern thought and it ranges in scope from the Presocratics through Plato, Aristotle, Plotinus and the late ancient period, on the one hand, and early Christian thought, especially Gregory of Nyssa, Augustine and, much later, Aquinas, on the other.
