1- Denis Diderot was a French Enlightenment philosopher who co-founded and edited an universal encyclopedia titled Encyclopédie.
L'Encyclopédie is an encyclopedia published between 1751 and 1772 in France under the direction of Denis Diderot and Jean le Rond d'Alembert. Its purpose was to gather and disseminate in clear and accessible text, the fruits of knowledge accumulated until then under the criticism and sieve of reason. In addition, it exposes the secularist, pragmatic, materialist and bourgeois ideology of the Enlightenment. It contains 72,000 articles of more than 140 collaborators, among them Voltaire, Rousseau or Turgot, to name a few.
It is considered one of the greatest works of the eighteenth century, not only for being the first French encyclopedia, but also for containing the synthesis of the main knowledge of the time, in a considerable editorial effort for its time.
