Nigeria is one of the most religious countries in the world. The major religions are Islam, Christianity, and African traditional religion. Nigeria is also notorious for ethno-religious conflicts, especially in the North eastern part of the country. Many factors have been identified as causes of the conflicts, including religious intolerance, desertification, poverty, cultural differences, foreign influences, and political differences. This paper argues that, although the conflicts were usually triggered by flimsy incidents, the protagonists’ exclusivistic attitude as regards value is the root cause of the conflicts. Each of the protagonists in the conflict, the ethnic and religious groups, regards its own worldview as the only true one. Using conceptual analytical method to analyse the Nigerian situation, this paper uses process philosophical concept of truth to propose that differences in value may not necessarily lead to conflicts. In fact, it may lead to deeper religion, beauty, and depth of personality. “Deep” or “Complementary” pluralism is thus recommended for tolerance and peace in Nigeria.
