*Ask someone today where Western Civilization originated, and he or she might say Greece or Rome. But what is the ultimate source of Western Civilization? Bestselling author and professor Thomas E. Woods, Jr. provides the long neglected answer: the Catholic Church. In the new paperback edition of his critically-acclaimed book, How the Catholic Church Built Western Civilization, Woods goes far beyond the familiar tale of monks copying manuscripts and preserving the wisdom of classical antiquity. Gifts such as modern science, free-market economics, art, music, and the idea of human rights come from the Catholic Church, explains Woods. In How the Catholic Church Built Western Civilization, you’ll learn:
Why modern science was born in the Catholic Church
How Catholic priests developed the idea of free-market economics five hundred years before Adam Smith
How the Catholic Church invented the university
Why what you know about the Galileo affair is wrong
How Western law grew out of Church canon law
How the Church humanized the West by insisting on the sacredness of all human life*
