The Catholic University of America Press is honored to announce the publication of the first volume of the critical English edition of The Collected Works of Karol Wojty?a/John Paul II. In conjunction with an international editorial board, the English Critical Edition will comprise 20 volumes, covering all of his writings and correspondence both in the years before and during his papacy. What makes this collection so important is that access to his writings have been a significant challenge. Except for official papal addresses and documents preserved and disseminated by the Vatican, his works have been scattered and limited, or in need of a new translation. Finally, English-language audiences have faced the challenge, even in the case of published texts, of working across multiple languages and translations and of dealing with textual idiosyncrasies. The inaugural volume of this collection is Person and Act, together with related essays, which is in many respects constitutes Karol Wojty?a’s most profound and well-known philosophical work. Originally published in 1969 as Osoba i czyn, this work of metaphysics and philosophy is widely influential even though it is highly challenging intellectually and has heretofore posed difficulties for translators.
