'Saint Thomas Aquinas' by G. K. Chesterton

 In this book, Chesterton offers clues to understand the thought of the great philosopher of the Middle Ages. Although he is not a specialist in Aquinas, he asserts that has drunk from the published books of others (J. Maritain).

Chesterton writes as an apologist. He struggles against, not only the enemies of the time of Aquinas, such as Bravante, but against the later enemies of the philosopher, such as Martin Luther, who burnt the great work of Aquinas, Summa Theologiae, and against the usual target group of Chesterton - modernists, agnostics and atheists-, such as Bernard Shaw.
The author does not swot on the theology of Aquinas, but only in his philosophy, his thought about the being, although he does it brilliantly.
This book is reader-friendly, I have read it in two days, and thought-provoking. For those who want to know what was said by the Mute Ox.
