Victor Hugo
Hugo's religious views changed radically over the course of his life. In his youth, he called himself as a Catholic and professed respect for Church hierarchy and authority. From there he became a non-practicing Catholic, and increasingly expressed anti-catholic views. He had a casual interest in Spiritualism during his exile (where he participated also in seances), and in later years settled into a Rationalist Deism similar to that espoused by Voltaire. A census-taker asked Hugo in 1872 if he was a Catholic, and he replied, "No. A Freethinker".
