Secularism is the concept that government or other entities should exist separately from religion and/or religious beliefs. In one sense, secularism may assert the right to be free from religious rule and teachings, and the right to freedom from governmental imposition of religion upon the people within a state that is neutral on matters of belief. (See also Separation of church and state and Laicity.) In another sense, it refers to the view that human activities and decisions, especially political ones, should be based on evidence and fact unbiased by religious influence. (See also public reason.) Secularism draws its intellectual roots from Greek and Roman philosophers such as Marcus Aurelius and Epicurus, medieval Muslim polymaths such as Ibn Rushd, Enlightenment thinkers like Denis Diderot, Voltaire, John Locke, James Madison, Thomas Jefferson, and Thomas Paine, and modern freethinkers, agnostics and atheists such as Bertrand Russell and Robert Ingersoll. The purposes and arguments in support of secularism vary widely. In European laicism, it has been argued that secularism is a movement toward modernization, and away from traditional religious values (also known as "secularisation"). This type of secularism, on a social or philosophical level, has often occurred while maintaining an official state church or other state support of religion. In the United States, some argue that state secularism has served to a greater extent to protect religion from governmental interference, while secularism on a social level is less prevalent.Within countries as well, differing political movements support secularism for varying reasons. The term "secularism" was first used by the British writer George Holyoake in 1851. Although the term was new, the general notions of freethought on which it was based had existed throughout history. In particular, early secular ideas involving the separation of philosophy and religion can be traced back to Ibn Rushd (Averroes) and the Averroism school of philosophy. Holyoake invented the term "secularism" to describe his views of promoting a social order separate from religion, without actively dismissing or criticizing religious belief. An agnostic himself, Holyoake argued that "Secularism is not an argument against Christianity, it is one independent of it. It does not question the pretensions of Christianity; it advances others. Secularism does not say there is no light or guidance elsewhere, but maintains that there is light and guidance in secular truth, whose conditions and sanctions exist independently, and act forever. Secular knowledge is manifestly that kind of knowledge which is founded in this life, which relates to the conduct of this life, conduces to the welfare of this life, and is capable of being tested by the experience of this life." Barry Kosmin of the Institute for the Study of Secularism in Society and Culture breaks modern secularism into two types: hard and soft secularism. According to Kosmin, "the hard secularist considers religious propositions to be epistemologically illegitimate, warranted by neither reason nor experience." However, in the view of soft secularism, "the attainment of absolute truth was impossible and therefore skepticism and tolerance should be the principle and overriding values in the discussion of science and religion. In political terms, secularism is a movement towards the separation of religion and government (often termed the separation of church and state). This can refer to reducing ties between a government and a state religion, replacing laws based on scripture (such as the Torah and Sharia law) with civil laws, and eliminating discrimination on the basis of religion. This is said to add to democracy by protecting the rights of religious minorities. Secularism is often associated with the Age of Enlightenment in Europe and plays a major role in Western society. The principles, but not necessarily practices, of separation of church and state in the United States and Laicity in France draw heavily on secularism. Secular states also existed in the Islamic world during the Middle Ages (see Islam and secularism). Due in part to the belief in the separation of church and state, secularists tend to prefer that politicians make decisions for secular rather than religious reasons. In this respect, policy decisions pertaining to topics like abortion, contraception, embryonic stem cell research, same-sex marriage, and sex education are prominently focused upon by American secularist organizations such as the Center for Inquiry.
