Anecdotes
In 1726, Voltaire was violently beaten by hired thugs acting on behalf of the Chevalier de Rohan, a nobleman he had offended with his mockery. Rather than seek revenge, Voltaire chose to exile himself to England for three years, where he discovered freedom of thought and political ideas that would shape his entire body of work. This traumatic experience drove him to become a passionate defender of tolerance and justice.
Voltaire maintained an intense correspondence with Frederick II of Prussia, the philosopher-king, for more than 50 years. Despite this celebrated friendship, the two men fell out in 1753 and Frederick even had Voltaire imprisoned for several months — a reminder that even the Enlightenment did not fully protect freedom of expression.
During the Calas Affair in 1762, Voltaire championed Jean Calas, a Protestant merchant wrongly accused of murdering his own son. Through his writings, he rallied public opinion and succeeded in securing a retrial and the posthumous exoneration of the condemned man, demonstrating the power of his pen in the fight for justice.
Voltaire stubbornly refused to return to Paris in his final years, fearing arrest by religious authorities hostile to his critical ideas. At the age of 83, he finally went back in 1778 and received a triumphant welcome — but he died just a few weeks later, already weakened by the journey.
The writer used the pen name 'Candide' for several of his works, most famously his celebrated philosophical tale, as a way to evade royal censorship and prosecution by the Church. This clever device allowed him to openly criticize religious intolerance and the absurdity of certain doctrines without risking imprisonment.

Let us dare say to those who have authority: we are all fallible, we are all prone to error. It is in the nature of man, as of all animals, to feed on what pleases him. A child believes his nurses, a young man believes his teachers, and a grown man believes his own eyes.

Daily Life
Morning
Voltaire wakes late, around 9 or 10 in the morning, after a night often spent writing. He has a light breakfast of coffee or hot chocolate — exotic drinks fashionable among men of letters in the 18th century. He immediately receives visitors in his bedroom or study, a common practice among Parisian philosophers who held morning audiences.
Afternoon
The afternoon is devoted to intensive correspondence with fellow philosophers, sovereigns, and friends across Europe. Voltaire works on his manuscripts, articles, and plays, often reclining in an armchair due to his chronic health problems. He also receives distinguished visitors and takes part in the literary salons of Paris, where he expounds his ideas.
Evening
Evenings are spent at intimate dinner gatherings or outings to the theatre to attend performances. Voltaire savors witty conversation with enlightened minds and figures of power. These moments provide opportunities to spread his ideas on tolerance and his critique of religious obscurantism.
Food
Voltaire follows a light diet suited to his fragile health: broths, poultry, fish, and fruit. He drinks coffee, tea, and red wine regularly, though in moderation. As a man of high society, he takes part in lavish meals at salon dinners, where 18th-century French cuisine takes center stage.
Clothing
Voltaire wears the typical dress of the French nobility of the robe in the 18th century: silk coat, knee breeches, silk stockings, and buckled shoes. He favors simple but quality garments, rejecting excessive ornamentation. His portraits often show him wearing a wig or a nightcap, a mark of his status as a man of letters.
Housing
Voltaire successively occupies several prestigious residences: a private mansion in Paris, then the estate at Cirey in Champagne, which he shares with Madame du Châtelet. His interiors reflect his standing: well-stocked libraries, a fully equipped study, and reception rooms for entertaining guests. These spaces become centers of intellectual life and philosophical debate.
