The idea of “secularism” is still rejected within the Arab cognitive structure at the level of intellectual, social and political construction. So far, Arab secularists have failed to find popular acceptance for secularism within the Arab cultural- religious structure and socio political sphere. As a result, traditional religious discourse and values still dominate minds!! The purpose of this study is to discuss, analyze and explain why secularism has not become the culture and political ideology of the Arab peoples and governments. The researcher assumes that the reasons are due to: the neglect of the cultural factor by the Arab secularists, the marriage of Arab nationalism and religion, the emergence of political Islam’s movements, and the nature of Islamic religion that rejects reform. Therefore, the researcher recommends that, there is a pressing need for reproducing Arabs prevailing traditional culture by promoting, a civil culture that privatize religion and separates it from politics and state affairs
