The Age of Reason

De: Thomas Paine

Narrado por: Michael Costantino

Thomas Paine, a political activist and member of the US Constitution, argues persuasively for a logical approach to theology in The Age of Reason. In keeping with the intellectual tradition of British Deism, Paine rejects the idea of divine revelation, claiming that "it is revelation to the first person only, and hearsay to every other." He continues by thoroughly examining the contradictions and historical errors in the Bible in order to reach the conclusion that it cannot be a work of divine inspiration. He claims that nature itself is the only true indicator of the existence of a divine creator, rejecting all organized religions in the process.

It had its first three editions published in 1794, 1795, and 1807, and it had a significant impact on the American freethinker movement. However, it was deemed seditious in Britain, where it led to the arrest of those who dared to print and distribute it.

"It is necessary to the happiness of man that he be mentally faithful to himself. Infidelity does not consist in believing, or in disbelieving, it consists in professing to believe what he does not believe." —Thomas Paine (The Age of Reason)

Textual criticism before it had a name.

I finished The Age of Reason expecting a historical critique of religion rooted in its time. What I didn’t expect was how intellectually rigorous Paine’s work would feel — almost like encountering biblical scholarship two centuries before scholars such as Bart Ehrman.
Rather than offering a simple polemic, Paine approaches the Old and New Testaments with careful reasoning, attention to authorship, contradictions, and historical context. His method resembles modern textual criticism: asking who wrote these texts, when, and why — and refusing to harmonize inconsistencies for the sake of doctrine.
Paine describes himself as a deist and expresses respect for groups like the Quakers, yet his analysis often feels closer to what today might be called agnostic atheism or scientific pantheism. Given the social consequences of openly identifying as an atheist in his time, this self-description makes historical sense.
What struck me most is how unapologetic yet non-confrontational the work feels. Paine isn’t attacking belief so much as defending reason and moral clarity. In that way, The Age of Reason feels less like a relic of 18th-century controversy and more like an early blueprint for the kind of thoughtful, evidence-based engagement with religious texts that continues today.
