Mansour Fahmy (1886-1959), one of the dramatic figures in modern Arab philosophical and social thought. He was the reformist and enlightenment figure in modern Arab history. He is also the owner of a notable current that was subjected to a violent attack that silenced him for a long time and forced him to "hide" physically. However, this did not eliminate the new opinions and positions that came at the beginning of the twentieth century towards the issue of women. He is the first to write with a scientific methodology - from the point of view of sociology - on Islamic discourse and its dealings with women. he sought to differentiate between religion and the religious establishment, between the personality of the Prophet Muhammad and what later prevailed in the books of jurisprudence and others. When he discussed the headscarf issue, he concluded that it was the product of traditions and customs that the Hijab is not from the Islamic religion. Islamic law has nothing to do with the Hijab. Mansour Fahmy's creativity was at one of the sensitive stages in Egypt's modern history in which the political, social, national, cultural, and revolution clashed in each one. All this, in turn, identified the problem of Mansour Fahmy's intellectual personality in the battles of thought and politics. This research's main task is to redraw the features of his actual personality and the reality of his intellectual, social, and political positions. Besides, this study seeks to uncover the effect of philosophy on crystallizing Mansour Fahmy's critical personality and its role in laying the foundations of the critical vision with its practical, reformist, and enlightening dimensions.
