Reason, the Only Oracle of Man; Or, A Compendius System of Natural Religion

Ethan Allen (1738–1789) was a prominent figure in early American history, most notably as a revolutionary leader and a key player in the efforts leading to the establishment of the state of Vermont. Allen gained initial fame as the leader of the Green Mountain Boys, a militia instrumental in capturing Fort Ticonderoga during the American Revolution. His contributions to American thought, however, extend beyond his military exploits. Allen was also a philosopher and author, best known for his work, 'Reason, the Only Oracle of Man; Or, A Compendius System of Natural Religion' (1784). In this treatise, Allen presented a deistic view of religion, emphasizing reason as the supreme guide in the pursuit of knowledge and denying the legitimacy of supernatural revelations. This work is considered an important contribution to American Enlightenment thought, elaborating on themes of rationality and skepticism which were hallmarks of the period. Allen's advocacy for religious freedom and criticism of orthodox Christianity were controversial at the time but have since been recognized as precursors to the values enshrined in the First Amendment. His legacy as an author is overshadowed by his role in American independence but nonetheless remains a vital component of the intellectual landscape of Revolutionary America.
