The political mobility following the First World War also created profound changes among Ottoman intellectuals. The political process working against the Ottoman Empire also caused some intellectual drifting among Arab intellectuals. Sâtı Bey, who maintained his literary and intellectual life on the axis of Ottomanism until 1919, is one of these important intellectuals. As a result of the decisions he made after the war, he opened a new page in his life where he would spend the rest of his life in various regions of the Arab world and became one of the most important advocates of the ideology of Arabism, which clearly marked his transformation from "Sâtı Bey" to "Sâtı al-Husri." Sâtı al-Husri, whom Hilmi Ziya Ülken defined as "the person who initiated the first modern movement in the education system in Maarif after the Constitutional Period," is a man of thought and action who came to the fore with his activities in Arab countries during this second phase of his life, which would last until his death. In his articles and conferences written in numerous magazines and newspapers in the Ottoman lands, he attached importance to subjects such as education and the determination to work, and examined these issues in light of the impressions he gained while in Europe. The debates he entered into with scientists, primarily Ziya Gökalp, during this period are among the unforgettable examples of our intellectual history. Historian William L. Cleveland, in his book examining the portrait of Sâtı al-Husri, known as the "philosopher of Arab nationalism," shifting from Ottomanism to Arab nationalism, states that he never used Arabic, his native language, in his writings until 1919. After this date, the Arabic language and culture were at the center of his activities. This work of the author, which we have translated under the title Language and Literature in the Mirror of Nationalism, is the version of his articles written at various dates that was compiled into a book within a thematic integrity by the author's own choice. In this work, where views on Arabic language and literature are handled from various aspects, the reader will have the opportunity to see the issues that still maintain their vitality today, albeit at different levels, from the perspective of an Ottoman-Arab intellectual and will witness the language, culture, and literature debates of the period.
