In this book, John F. Crosby answers these questions by unfolding the mystery of personal individuality or uniqueness, or as he calls it personal selfhood. He stands in the great tradition of Western philosophy and draws on Aquinas wherever possible, but he is also deeply indebted to more recent personalist philosophy, especially to the Christian personalism of Kierkegaard and Newman and to the phenomonology of Scheler and von Hildebrand. As a result, Crosby, in a manner deeply akin to the philosophical work of Karol Wojtyla, enriches the old with the new as he explores the structure of personal selfhood, offering many original contributions of his own.
