"May this book, in spite of its rather abstract character, give to those who read it the real joy which is the result of having seen the truth, and cause them to have greater love for the Author of all goodness, in whom we must find our happiness." - From the Preface To The Third Edition About the Author: Réginald Marie Garrigou-Lagrange, (1877-1964), a French Dominican priest, was one of the greatest Catholic theologians and Neo-Scholastics of the 20th century. He taught at the Dominican Pontifical University of St. Thomas Aquinas, Angelicum in Rome from 1909 to 1960. Many of his students would become eminent Catholic theologians, including Pope Saint John Paul II. Fr Garrigou-Lagrange also served as theological advisor to four Popes, including Pope Saint John XXIII. - from Amzon
