Which of these was one the great French literature successes Enlightenment?

The question is a bit tricky. The Enlightenment, as a philosophical movement, didn't have "successes" in the way a book or a play would. It's a period of thought and cultural shift that influenced many works of art and literature.

However, we can identify works of French literature that embody Enlightenment ideals. Some of the most prominent examples include:

* "Candide" by Voltaire (1759): This satirical novel criticizes religious dogma, political corruption, and philosophical optimism, embodying the Enlightenment's spirit of reason and skepticism.

* "The Social Contract" by Jean-Jacques Rousseau (1762): This treatise on political philosophy argues for a society based on the consent of the governed and the general will, a key concept of the Enlightenment.

* "The Spirit of the Laws" by Montesquieu (1748): This work explores different forms of government and advocates for the separation of powers, a cornerstone of modern democratic thought.

* "Encyclopédie" by Denis Diderot and Jean le Rond d'Alembert (1751-1772): This monumental collection of knowledge aimed to disseminate information and promote Enlightenment ideals of reason and progress.

It's important to note that these are just a few examples, and many other works of French literature from the Enlightenment period could be considered "successes" in their own right. The Enlightenment was a complex and multifaceted movement that influenced a wide range of literary and artistic expression.
