'If God did not exist, it would be necessary to invent Him'

Already in the 18th century, Voltaire was negatively portrayed as a free-thinker, atheist undermining the religious faith and society's morals. By the end of the 19th century, this myth was firmly established in the public mind. For instance, the article Voltaire as Leader and Simbol of French Disbelief describes the thinker as follows:

Voltaire really was the great supporter and propagator of rationalism in modern Europe. He was the evil genius of the past century on which he left the deep imprint of his thoughts, at the same time, he had all the flaws and vices of the time, under the weight of which his good intentions (that were not unusual for him) were crushed.

Voltaire, as a true son of his age, was born and raised in an environment that, from the very first moments of his consciousness awakening, had drugged his soul with the poison of frivolity, skepticism and immorality¹.

Contrary to the popular myth, Voltaire wasn't an atheist at all, while it was true that he opposed religious fanaticism. It is no accident that one of his favorite sayings was the aphorism, "If God did not exist, it would be necessary to invent Him" ('Si Dieu n’existait pas, il faudrait l’inventer'). The philosopher first published these words in the Epistle to the Author of "The Three Impostors" in 1769. Voltaire addressed this poetic message to the anonymous writer of the Treatise of the Three Impostors, the 18th century atheistic essay against all three world religions and their founders — Moses, Jesus Christ and Mohammed. The Voltaire Library has a copy of this treatise with Voltaire's inscription "A Dangerous Book" (БВ 2–63). Voltaire sent copies of the epistle to many people. In his correspondence on this poem, Voltaire emphasizes that he fights against both superstition and atheism. In a letter dated March 12, 1769 to his niece, Mme Denis, the thinker wrote,

"This morning I had fun writing an epistle against the book of the three impostors. I have just finished it. I will send it to you. I believe atheism is as pernicious as superstition.

In a letter to the Marquise du Deffant, to whom he sent also a copy of the Epistle, the thinker notes,

"Here is a little essay against atheism, part of which is edifying, the other is somewhat playful".

In 1773, Voltaire repeats this aphorism, which asserts the necessity of the existence of God and faith in him, in the Speech by Me. Belleguier (1773):

The astronomer who whatches the motions of stars, established according to the laws of the most profound mathematics, must adore the Eternal Geometer. The physicist who investigates a grain of wheat or an animal body must recognize the Eternal Craftsman. The moral man who seeks a support point in virtue must admit the existence of a Being as fair as He is supreme. So God is necessary to the world in every way, and we can say together with the author of the Epistle to the scribbler of a vulgar book on the Three Impostors, "If God did not exist, it would be necessary to invent Him".

In 1774, Voltaire once again wrote his favorite aphorism on an additional sheet inserted before the title page of the anonymous atheist treatise The True Sense of Nature's System. The treatise, published under the name of Helvétius, is kept in the Voltaire Library (БВ 2–42).
