In Age of Reason, Thomas Paine boldly challenges the authenticity of the Old and New Testaments, revealing that many biblical books have been misattributed to their supposed authors and cannot be definitively proven as the “word of God.” As a self-identified deist, Paine argues that the physical universe and each individuals conscience are the only true revelations of the Almightys essence and will. Grounded in reason and common sense, he uses the Bible itself as his sole scholarly resource to critique the biblical depiction of God, whom he views as a cruel and capricious figure, starkly contrasting with the benevolent deity reflected in the beauty of creation. Written during the tumultuous period of the French Revolution, while Paine faced grave personal peril, the first volume emerges as a passionate plea for reason. The second, more extensive volume delves deeper into the scriptures, using them to further undermine their authenticity. Finally, a brief concluding volume features personal letters addressing various objections. - Summary by Thomas Copeland
