20 Voltaire Quotes to Improve your Rational Thinking

François-Marie Arouet, known by his pen name Voltaire, is considered one of France's greatest writers from the Age of Enlightenment period.

Voltaire was a man of reason, a deist who loathed fanaticism, superstition, idolatry and mostly the fact that men are capable of killing each other to defend a religious doctrine that they scarcely understand.

His attitude toward religion and authorities was not well received in France and as a result, he was twice sentenced to prison and once to temporary exile to England.

Voltaire’s best-known work is Candide. The satirical novella of the human condition published in 1759, was a best-seller from the moment it appeared and was translated into every possible language.

Voltaire said of himself that he “wrote to act” and his greatest desire as a philosopher was to change people’s way of thinking and behaving. He strongly believed in reason, tolerance, freedom of speech and a free and liberal society.
