Joseph McCabe was a prominent English writer and speaker on freethought, known for his prolific output and staunch criticism of the Catholic Church. Originally ordained as a Franciscan priest under the name Father Antony, he left the church in 1896 to become a leading advocate for rationalism and secularism. Throughout his career, he authored nearly 250 books and thousands of pamphlets and articles on a vast range of subjects, including science, religion, and history. McCabe's work remains influential in humanist and freethinking circles, cementing his legacy as a tireless champion of reason over faith.
