There were many notable thinkers and writers in France in the eighteenth century. The most famous writer of the time on rationalistic and scientific subjects was Voltaire (1694 – 1778). When imprisoned and banished, he had to live at Femey near Geneva. Voltaire, Montesquieu (1689 – 1755) and Rousseau criticized the then existing conditions in France. Voltaire, was a prolific writer and activist, and was vehement in his criticism of the Church. His most famous work was Candide. His famous quote was: “those who can make you believe absurdities can make you commit atrocities.” He is said to have once exclaimed, “I disapprove of what you . say, but I will defend to the death your right to say it.”
Another great writer, a contemporary of Voltaire, but younger than him, was Jean Jacques Rousseau (1712 – 1778). His political theory set the minds of many afire with new ideas and new resolves. His ideas played an important part in preparing the people of France for the great revolution. He famously said in his book Social Contract, “Man is born free, but is everywhere in chains.” He argued that the laws are binding only when they are supported by – the general will of the people.
Montesquieu (1689 — 1755), who wrote The Persian Letters and The Spirit of the Laws, also defended liberty. He put forward the theory of separation of powers: The liberty of the individual would be best protected only in a government where the powers of its three organs, viz., legislature, executive and judiciary were separate. It would put in place the necessary checks and balances to prevent any one organ from assuming more power to itself.
An Encyclopaedia also came out in Paris about this time and this was full of articles by Diderot and Jean d’Alembert. These philosophers and thinkers, as opposed to religious intolerance and political and social privileges, succeeded in provoking large numbers of ordinary people to think and act.
