Abstract
In his disputatio, Johann Peter von Ludewig provides a history of rational philosophy among the Arabs and sets out to contextualize the Turks’ attitude to it. Like many Lutheran scholars of the time, Ludewig believed that Islam, as a religion, impeded the development of rational philosophy in the Arab world. However, unlike those philosophers, he examines external influences that may have fed the interest of Arab Muslims in rational philosophy, especially dialectic. Unlike Orthodox Lutherans, such as Pfeiffer and Kromayer, in his conclusion, Ludewig prays that Muslim philosophers cultivate reason to overcome the "deceit of Muhammadanists" toward rational worship. The use of the contentious and seemingly oxymoronic phrase “rational worship” (logikē latreia: λογική λατρεία, from Rom. 12:1), combining “rationality” and “worship” together refects, to a certain extent, the Enlightenment belief that reason could be used to understand the nature of God against any type of irrational religiosity. The idea of worshipping God rationally and equating God with reason shows the intellectual engagement of Protestant scholars with Enlightenment rationalism.
