This is a brilliant, cogent masterpiece; a fitting opus to well-round the life work of one of history’s intellectual giants. By employing a prose that is both lucid and surprisingly vernacular, the ideas presented should be accessible to most of today’s readers. Thomas Paine exposes and discusses critical discrepancies, contradictions, and patent irrationalities contained within the core precepts of the Jewish, Christian, and Muslim religious systems. Therefore, I presume that for the religiously inclined -- and as evidenced by one review below -- Paine’s work may represent a considerable philosophical threat. Mark Twain wrote, “It took a brave man before the Civil War to confess he had read The Age of Reason. [...] I read it first when I was a cub pilot, read it with fear and hesitation, but marveling at its fearlessness and wonderful power.”
