"Voltaire's Philosophical Dictionary" by Voltaire is an encyclopedic dictionary published in 1764. This alphabetically arranged work criticizes the Roman Catholic Church, Judaism, Islam, and other institutions through sharp, provocative articles. Initially released anonymously with 73 entries, it expanded over time as Voltaire refined his views on Christianity, God, and morality. The portable, affordable format made revolutionary ideas accessible to ordinary readers. While the public embraced it enthusiastically, religious authorities condemned and burned copies across Europe, cementing its status as a defining work of Enlightenment thought.
