This book treats the ever-relevant philosophy of St. Thomas Aquinas, who lives on today through his 20th century interpreters, such as Maritain and Gilson. More recently, von Balthasar has added new insights and fresh interest in the philosophy of Aquinas, which have been incorporated in the text. With the renewal in the Catholic Church, this fresh philosophy tries to answer the challenge, covering the various areas of speculative philosophy.
