The relation between psychology and morality in Galenos, Abu Bakr er-Razi and Farabi

According to Galen, Abu Bakr ar-Razi and Farabi, indeed the ethic is strongly connected with human physiology and psychology. In fact, analysing ethic without taking the related sciences into consideration causes a methodological errors. The relation of physics- psychology-ethic has gone through various stages throughout history, however today it is facing a dissolution. Even though some studies in the field of psychology and neuroscience have focused on re-establishing this relationship, satisfactory results have not been obtained from these studies due to the fact that the disciplines still address the object with their own perspectives. In order to shed light upon the issue, the thesis examined the historical processes and continuities through Galen, Ebu Bekir ar-Razi and Farabi in order to establish this relationship. Examining the important phases of this relation in the historical process shows us to rethink this relation in the modern context. All three names discussed in the thesis are considered as the key names for this relation. Galen handled this relation by formulating in systematic way, Razi included the faculty of will into the system, and lastly Farabi made this relation work by determining the place of prophethood and giving it a social dimension. Examining how each thinkers deepened and transformed the tradition that inherited signifies some clues in order to reconsider the connection today.
