A Letter Concerning Toleration Author:John Locke A Letter Concerning Toleration by John Locke was originally published in 1689. One of the founders of Empiricism, Locke develops a philosophy that is contrary to the one expressed by Thomas Hobbes in Leviathan, in supporting toleration for various Christian denominations. Hobbes did allow for individuals to maintain their own religious belief... more »s as long as they outwardly expressed those of the state, however, and it has been argued that Locke's rejection of Catholic Imperialism was the ultimate basis for his rejection of government's interest in spiritual salvation. Unlike Hobbes, who saw uniformity of religion as the key to a well-functioning civil society, Locke argues that more religious groups actually prevent civil unrest. Locke argues that civil unrest results from confrontations caused by any magistrate's attempt to prevent different religions from being practiced, rather than tolerating their proliferation. Locke's primary goal is to "distinguish exactly the business of civil government from that of religion." He seeks to persuade the reader that government is instituted to promote external interests, relating to life, liberty, and the general welfare, while the church exists to promote internal interests, i.e., salvation. The two serve separate functions, and so, must be considered to be separate institutions.« less
