Age of Reason: Being an Investigation of True and Fabulous Theology

he Age of Reason by Thomas Paine, first published in three parts between 1794 and 1807, is a treatise that challenges institutionalized religion and advocates for deism. Paine critiques the doctrines of Christianity, arguing that reason, rather than revelation or religious authority, should guide belief. The work was controversial at the time for its direct criticism of organized religion, yet it became a foundational text in Enlightenment thought, promoting the idea of a more rational approach to spirituality.
