In political terms, secularism is the principle of the separation of government institutions and personspmandatedto represent the statefromreligious institutionsandreligious dignitaries(the attainment of such is termedsecularity). Defined briefly, secularism means that governments should remain neutral on the matter of religion and should not enforce nor prohibit the free exercise of religion, leaving religious choice to thelibertyof the people. One form of secularism is asserting the right to be free from religious rule and teachings, or, in a state declared to be neutral on matters of belief, from the imposition by government of religion or religious practices upon its people.Another form of secularism is the view that public activities and decisions, especiallypoliticalones, should be uninfluenced by religious beliefs or practices.
