This a profound and poetic assessment of the relationship between Christianity and liberty, between politics and society, and between Christianity and the modern world. This edition includes a new foreword by Pierre Manent, professor of Political Science at the Centre de Recherches Politiques Raymond Aron in Paris. As the 21st century begins, the relationships this book explores are as relevant as they were in the last century, when French poet and essayist Charles Pguy addressed them in "Memories of Youth" and "Clio I", the two essays in this volume. In these essays Pguy develops his theme of la mystique -- that which a person or a nation is -- and la politique -- mere policy.
