Voltaire’s afterlife is complex, his reputation changing with successive regimes. The French Revolution looked back to him as a heroic precursor of its struggle, and in 1791 his remains were brought back to Paris and with great ceremony placed in the Panthéon. For much of the nineteenth century the name of Voltaire was synonymous with anticlericalism, and the philosophe was widely, if implausibly, seen as an Antichrist. In the wake of the Dreyfus affair Voltaire’s reputation as a crusader for tolerance was re-emphasised, and in the latter years of the Third Republic, under the influence of the Sorbonne literary historian Gustave Lanson, Voltaire became a fixture of the republican school and university curriculum. The latter half of the twentieth century has taken a more nuanced approach to Voltaire’s religious views, especially in the wake of René Pomeau’s La Religion de Voltaire (first published in 1954), which stresses the depth of Voltaire’s deist convictions.
Voltaire’s legacy in the wider world is ubiquitous. His name has become a byword for tolerance, justice and the power of reason whenever fanaticism, tyranny and superstition rear their ugly heads. Famously, portraits of him spontaneously appeared on the walls of the French capital in the aftermath of the Charlie Hebdo atrocity in 2015. Several years before the attack, in 2008, then editor-in-chief of the satirical magazine, Philippe Val, had published a book entitled Reviens, Voltaire, ils sont devenus fous!, and philosopher André Glucksmann’s last book, published in 2014 (one year before he died), is called Voltaire contre-attaque.
Voltaire is undoubtedly the most widely quoted of all French writers past and present. Everyone is familiar with his ‘il faut cultiver son jardin’, ‘le meilleur des mondes possibles’, and ‘si Dieu [which can be replaced with anything deemed to be of value, no matter how trivial] n’existait pas, il faudrait l’inventer’. These three quotations happen to be genuine and traceable; interestingly, however, we at the Voltaire Foundation often receive queries from scholars and members of the public alike asking about the provenance of various Voltaire quotes which, after diligent research, turn out to be apocryphal. It is as if witty and wise pronouncements in search of an author were routinely attributed to him by default.
Ironically, what must be the most famous and oft-repeated quotation by Voltaire does not appear anywhere in his writings or his correspondence. Elizabeth Knowles picks up the story:
“A column in the Daily Telegraph of February 2006 on freedom of speech referred to ‘Voltaire’s famous maxim – “I disapprove of what you say, but I will defend to the death your right to say it.” ’
“In De l’esprit (‘On the Mind’), published in 1758, the French philosopher Helvétius put forward the view that human motivation derives from sensation: a course of action is chosen because of the pleasure or pain which will result. The book was seen by many as an attack on religion and morality, and was condemned by the French parliament to be publicly burned. Voltaire is supposed to have supported Helvétius with these words. In fact, they are a later summary of Voltaire’s attitude to the affair, as given in S. G. Tallentyre’s The Friends of Voltaire (1907). What Tallentyre wrote was:
“‘What the book could never have done for itself, or for its author, persecution did for them both. “On the Mind” became not the success of a season, but one of the most famous books of the century. The men who had hated it, and had not particularly loved Helvétius, flocked round him now. Voltaire forgave him all injuries, intentional or unintentional. “What a fuss about an omelette!” he had exclaimed when he heard of the burning. How abominably unjust to persecute a man for such an airy trifle as that! “I disapprove of what you say, but I will defend to the death your right to say it,” was his attitude now.’
“(The comment ‘What a fuss about an omelette!’ had been recorded earlier, in James Parton’s 1881 Life of Voltaire.)” 
We will end this short blog article on this culinary note. Readers who are curious about the origin of this particular quote are invited to consult Lettres à Son Altesse Monseigneur le prince de *** (letter 7) or the article ‘Athéisme’ in the Questions sur l’Encyclopédie.
