It is important to notice that Baumgarten's first work preceded those of Burke, Diderot, and P. Andre, and that Kant had a great admiration for him.
Alembert's association with Diderot in the preparation of the Dictionnaire Encyclopedique led him to take a somewhat wider range than that to which he had previously confined himself.
Within a few months of her accession, having heard that the publication of the famous French Encyclopedie was in danger of being stopped by the French government on account of its irreligious spirit, she proposed to Diderot that he should complete his great work in Russia under her protection.
He first visited Paris, where he saw a good deal of d'Alembert, Diderot, Barthelemy, Raynal, Helvetius, Baron d'Holbach and others of that circle, and was often a welcome guest in the saloons of Madame Geoffrin and Madame du Deffand.
In Paris she secured the warm friendship and admiration of Diderot and Voltaire.
