Voltaire (real name François-Marie Arouet) (21 November 1694 – 30 May 1778) was a French writer, historian and philosopher. His intelligence, wit and unique style made him one of France’s greatest writers and philosophers and a leading figure of French Enlightenment. He advocated fiercely for civil liberties, including freedom of religion, freedom of expression, free trade and separation of church and state. He disliked and targeted in his writings (Christian) dogmatism and orthodoxy.
Voltaire wrote a number of pamphlets as polemical satires. Candide is a great excellent example of his style where he attacks the optimistic determinism of Leibniz's philosophy (i.e., the motto that we are living in the best of possible worlds). Zadig is written against orthodoxy and religious dogma. Other works attack the established dogmatic institutions of various kinds.
