Explanation: Voltaire and Adam Smith were both famous philosophers. Both of them lived mainly during the 18th century, which is known as "the century of reason". While Voltaire wrote the Treatise On Toleration (1763), Adam Smith wrote The Wealth of Nations (1776). Smith was greatly influenced by Newton's theories, which he used to explain the laws of economics. On the other hand, during his life, Voltaire focused on defending freedom of speech as well as freedom of religion. In that way, Voltaire was in favour of spreading religious tolerance.
