The Age of Reason: Deism and Free Thought

The pamphleteer who attacked kings turned last on the churches - defending belief in God by reason alone while subjecting scripture to fearless criticism, a book that made him a hero to freethinkers and an outcast to the pious.

From the lesson

Having helped overturn kings in two revolutions, Paine turned in 1793–94 to what he regarded as the last and deepest tyranny: the tyranny of established religion over the human mind. He wrote The Age of Reason partly in the shadow of the French Revolution’s violent assault on the Church, and partly from a fear that the revolutionaries, in throwing off Christianity, would throw off all belief in God and morality with it. He wrote much of it, by his account, in haste before his arrest by the Jacobins, expecting to be sent to the guillotine - so the book is in part the testament of a man who thought he was about to die.

Far from being the atheist his enemies branded him, Paine opened the book with a clear profession of faith. He believed in one God; he hoped for happiness in a life beyond this one; he held that true religion consists in doing justice, loving mercy, and trying to make our fellow creatures happy. What he rejected was not God but the churches - the institutions, creeds, priesthoods, and sacred books that he believed had set themselves up between human beings and their Creator, and had used the name of God to enslave the mind, extort money, and justify cruelty. It was a profession of faith aimed like a cannon at organized religion.

The animating principle of The Age of Reason is the same one that runs through all of Paine’s work: that authority must answer to individual reason, and that no institution may stand between a person and the truth. In politics this had meant rejecting kings; in religion it meant rejecting priesthoods and creeds. Paine refused to accept any belief on the mere authority of a church, a tradition, or a sacred text. He would believe only what his own reason, examining the evidence, found credible. ‘I do not believe in the creed professed by the Jewish church, by the Roman church, by the Greek church, by the Turkish church, by the Protestant church, nor by any church that I know of,’ he wrote; ‘my own mind is my own church.’

This was a declaration of intellectual independence as radical, in its sphere, as the Declaration of Independence had been in its. It located religious authority not in any external institution but in the conscience and reason of the individual believer - the same democratic move Paine had made in politics, applied to the soul. Every person, he held, has the faculty of reason and the evidence of the created world before them, and these are enough to know the great truths: that there is a Creator, that we should be just and merciful, that there is likely a life to come. We need no priest to mediate, no church to interpret, no book to reveal. The implication was explosive for an age in which church and state were intertwined and unbelief could cost one one’s livelihood or worse: Paine was telling every reader that the keys to truth were in their own hands, and that the vast edifice of organized religion was an imposition upon a faculty they already possessed.

Paine’s positive religion - what he believed rather than what he denied - centred on the idea that the universe is the genuine and sufficient revelation of God. The Bible, he argued, was written, copied, translated, edited, and selected by fallible and often interested human beings across centuries; its claims to be the direct word of God could not be verified and were riddled, in his reading, with contradictions, cruelties, and absurdities. The creation, by contrast, is God’s own unforgeable handiwork, available to every person of every nation and tongue, telling the same consistent story to all who examine it. To study the structure of the universe - the motions of the planets, the laws of nature, the intricate order of living things - was therefore, for Paine, the highest and truest form of religious devotion, and the proper foundation of any honest theology.

This is why Paine wove long passages of popular astronomy into a book about religion, marvelling at the scale of the solar system and the plurality of worlds, and arguing that the immensity and order of the cosmos teach us more of God’s power and wisdom than any number of ancient miracles. It also shaped his moral teaching: true religion, he insisted, is not in believing the right doctrines or performing the right rites but in conduct - in doing justice, loving mercy, and seeking the happiness of one’s fellow creatures, which he took to be the obvious moral law written into our nature by the same Creator who wrote the laws of motion into the stars. Strip away the ‘fabulous theology’ of the churches, Paine believed, and what remains is a religion at once rational, universal, and humane: one God, known through His works, served by goodness to one another.

This is the opening of the lesson. The rest — the dialogue, the primary source, and the recall — is in the app.

What you'll be able to recall

You learned that Paine defended belief in one God while rejecting organized religion and revealed scripture. In your own words, what did he mean by ‘my own mind is my own church’?

Leads to Voltaire.
