Charles Peguy (1873-1914)

Charles Pierre Péguy was a French poet, essayist, and editor. His two main philosophies were socialism and nationalism; by 1908 at the latest, after years of uneasy agnosticism, he had become a believing Roman Catholic.
From that time, Catholicism strongly influenced his works.

Quotes

The honest man must be a perpetual renegade, the life of an honest man a perpetual infidelity. For the man who wishes to remain faithful must take himself perpetually unfaithful to all the continual, successive, indefatigable, renascent errors.

A great philosophy is not one that passes final judgments and establishes ultimate truth. It is one that causes uneasiness and starts commotion.
