How I suffered when I had to preach to you those pious lies that I detest in my heart. What remorse your credulity caused me! A thousand times I was on the point of breaking out publicly and opening your eyes, but a fear stronger than myself held me back, and forced me to keep silence until my death.

Jean Meslier was a French Catholic priest who was discovered, upon his death, to have written a book-length philosophical essay promoting atheism and materialism. Described by the author as his "testament" to his parishioners, the text criticizes and denounces all religions.


Jean Meslier was born in Mazerny in the Ardennes. He began learning Latin from a neighbourhood priest in 1678 and eventually joined the seminary; he later claimed, in the Author's Preface to his Testament, this was done to please his parents. At the end of his studies, he took Holy Orders and, on 7 January 1689, became priest at Étrépigny, in Champagne.

One public disagreement with a local nobleman aside, Meslier was to all appearances generally unremarkable, and he performed his office without complaint or problem for 40 years. He lived like a pauper, and every penny left over was donated to the poor.

When Meslier died in Étrépigny, there were found in his house three copies of a 633-page octavo manuscript in which the village curate denounces organised religion as "but a castle in the air" and theology as "but ignorance of natural causes reduced to a system".


In his Testament, Meslier repudiated not only the God of conventional Christianity, but even the generic God of the natural religion of the deists. For Meslier, the existence of evil was incompatible with the idea of a good and wise God. He denied that any spiritual value could be gained from suffering, and he used the deist's argument from design against god, by showing the evils that he had permitted in this world. To him, religions were fabrications fostered by ruling elites; although the earliest Christians had been exemplary in sharing their goods, Christianity had long since degenerated into encouraging the acceptance of suffering and submission to tyranny as practised by the kings of France: injustice was explained away as being the will of an all-wise Being. None of the arguments used by Meslier against the existence of God were original. In fact, he derived them from books written by orthodox theologians in the debate between the Jesuits, Cartesians, and Jansenists. Their inability to agree on a proof for God's existence was taken by Meslier as a good reason not to presume that there were compelling grounds for belief in God.

Meslier's philosophy was that of an atheist. He also denied the existence of the soul and dismissed the notion of free will. In Chapter V, the priest writes, "If God is incomprehensible to man, it would seem rational never to think of Him at all". Meslier later describes God as "a chimera" and argues that the supposition of God is not prerequisite to morality. In fact, he concludes that "Whether there exists a God or not men's moral duties will always be the same so long as they possess their own nature".

Church of Étrépigny, the parish church where Meslier preached.

In his most famous quote, Meslier refers to a man who "wished that all the great men in the world and all the nobility could be hanged, and strangled with the guts of the priests." Meslier admits that the statement may seem crude and shocking, but comments that this is what the priests and nobility deserve, not for reasons of revenge or hatred, but for love of justice and truth.

Equally well-known is the version by Diderot: "And the guts of the last priest let's strangle the neck of the last king." During the political unrest of May 1968, the radical students of the Sorbonne Occupation Committee paraphrased Meslier's epigram, stating that "humanity won’t be happy till the last capitalist is hung with the guts of the last bureaucrat."

Meslier also vehemently attacked social injustice and sketched out a kind of rural proto-communism. All the people in a region would belong to a commune in which wealth would be held in common, and everybody would work. Founded on love and brotherhood, the communes would ally to help each other and preserve peace.

Voltaire's Extrait

Various edited abstracts known as "extraits" of the Testament were printed and circulated, condensing the multi-volume original manuscript and sometimes adding material that was not written by Meslier. Abstracts were popular because of the length and convoluted style of the original.

Voltaire often mentions Meslier referring to him as "a good priest" in his correspondence, in which he tells his daughter to "read and read again" Meslier's only work, and says that "every honest man should have Meslier's Testament in his pocket." However, he also described Meslier as writing "in the style of a carriage-horse".

Voltaire published his own expurgated version as Extraits des sentiments de Jean Meslier first edition, 1762. Voltaire's edition changed the thrust of Meslier's arguments or drew on other Extraits which did this so that he appeared to be a deist—like Voltaire—rather than an atheist.

The following passage is found at the end of Voltaire's Extrait, and has been cited in support of the view that Meslier was not really an atheist. However, the passage does not appear in either the 1864 complete edition of the Testament, published in Amsterdam by Rudolf Charles, or in the complete works of Meslier published 1970–1972.

I will finish by begging God, so outraged by that sect, to deign to recall us to natural religion, of which Christianity is the declared enemy. To that simple religion that God placed in the hearts of all men, which teaches us that we only do unto others what we want to have done unto us. Then the universe will be composed of good citizens, of just fathers, of submissive children, of tender friends. God gave us this religion in giving us reason. May fanaticism no longer pervert it! I die more filled with these wishes than with hopes. This is the exact summary of the in-folio testament of Jean Meslier. We can judge how weighty is the testimony of a dying priest who asks God's forgiveness.

Another book, Good Sense French: Le Bon Sens, published anonymously in 1772, was long attributed to Meslier, but was in fact written by Baron d'Holbach.

The complete Testament of Meslier was published in English translation by Michael Shreve for the first time in 2009.


In his book In Defense of Atheism 2007 the atheist philosopher Michel Onfray describes Meslier as the first person to write an entire text in support of atheism:

For the first time (but how long will it take us to acknowledge this?) in the history of ideas, a philosopher had dedicated a whole book to the question of atheism. He professed it, demonstrated it, arguing and quoting, sharing his reading and his reflections, and seeking confirmation from his own observations of the everyday world. His title sets it out clearly: Memoir of the Thoughts and Feelings of Jean Meslier; and so does his subtitle: Clear and Evident Demonstrations of the Vanity and Falsity of All the Religions of the World. The book appeared in 1729, after his death. Meslier had spent the greater part of his life working on it. The history of true atheism had begun.

Prior to announcing Meslier as the first atheist philosopher, Onfray considers and dismisses Cristóvão Ferreira, a Portuguese and former Jesuit who renounced his faith under Japanese torture in 1633 and went on to write a book titled The Deception Revealed. However, Onfray decides that Ferreira was not such a good candidate as Meslier, since Ferreira converted to Zen Buddhism.

The Situationist cultural theorist Raoul Vaneigem praised Meslier's resistance to hierarchical authority, claiming that "the last full-fledged exemplars of priests genuinely loyal to the revolutionary origins of their religion were Jean Meslier and Jacques Roux fomenting jacquerie and riot".

According to Colin Brewer 2007, who co-produced a play about Meslier's life,

Historians argue about who was the first overt, post-Classical atheist but Meslier was arguably the first to put his name to an incontrovertibly atheist document. That this important event is largely unrecognised (Meslier was absent from both Richard Dawkins’ and Jonathan Miller's recent TV series on atheism) is due partly to Voltaire who published, in 1761, a grossly distorted "Extract" that portrayed Meslier as a fellow-deist and entirely suppressed Meslier's anti-monarchist, proto-communist opinions.
