Jean-Baptiste de Boyer, Marquis d'Argens
1704–1771 · French Enlightenment philosopher and writer
Jean-Baptiste de Boyer, Marquis d'Argens, was a French writer and philosopher of the Enlightenment. Born in Aix-en-Provence in 1704, he died near Toulon in 1771. He brought the rationalist and anti-clerical ideas of Voltaire, Bayle and Fontenelle to a wide readership, writing in a light, combative style that made philosophy easy to follow.
After a restless youth in the army, which cost him his inheritance, he settled in the Netherlands. There he published the Lettres juives, followed by the Lettres chinoises and the Lettres cabalistiques. In 1742 Frederick the Great invited him to Berlin, where he held a post as chamberlain and took on duties at the Academy. He stayed there for nearly three decades, returning to Provence in 1769.
His writings attacked the Catholic Church, especially the Jesuits, and argued for a society governed by reason, though not against monarchy itself. His Histoire de l'esprit humain gathered his historical and philosophical reading. He is also credited with the novel Thérèse philosophe, though its authorship remains disputed. His lasting contribution was popular: he made Enlightenment criticism accessible to readers with no specialist training.
Key ideas
- Critical rationalism: reason should examine religious belief and tradition, including the authority of the Church.
- Opposition to the Jesuits: his hostility to the Society of Jesus shaped much of his writing and his public reputation.
- Separation of church and state: he supported a society grounded in reason and tolerance, without rejecting the monarchy.
- Popular Enlightenment: he carried the ideas of other thinkers to a general audience, simplifying them with plain, empirical arguments.
Curiosities
A reputation for poor hygiene
According to James Boswell's account of his Grand Tour, the marquis boasted of not having changed his underclothes in fifteen years. When Frederick of Prussia received him, the garment had stuck to his skin and had to be soaked off.
An unsigned novel
Thérèse philosophe was published anonymously, and d'Argens himself denied writing it. The novel draws on the Cadière witchcraft trial, which he had followed closely.
