These writers, and others such as the Abbé Sieyès, one of the main authors of the Declaration of the Rights of Man and of the Citizen, became known as the "philosophes". They came from the wealthy upper class or Third Estate, sought a society founded upon talent and merit, rather than a society based on heredity or caste. Their ideas were strongly influenced by those of John Locke in England. They introduced the values of liberty and equality which became the ideals of the French Republic founded at the end of the century. They defended the freedom of conscience and challenged the role of religious institutions in society. For them, tolerance was a fundamental value of society. When the Convention placed the ashes of Voltaire in the Pantheon in Paris, they honored him as the man who "taught us to live as free men."
