We can trace the ancient Greek philosophy and modern Western thoughts as similar processes of perfection of human thought in the history. The Greek thought which arosed in 8th century BC evolved during the next three centuries and reached its high point in the careers of three philosophers, i.e. Socrates, Plato and Aristotle. And, it is generally accepted that Greek thought was systematized in their days. The same holds true for modern Western thought. It arosed in 14th century AD as a movement of humanistic revival of classical art, arcitecture, and literature, which is known as Renaissance, and developed into a robust ideology i.e. Enlightenment which emphasized reason, analysis, and individualism rather than traditional lines of authority. This is the time the thought was systematized. At the end, this evolutionary process produced two "schools of thought" named as liberalism and socialism. We can easily say that the jurisprudential, teological and political schools of thought in Muslim history were, in many ways, the experiences of similar nature. Ahl'ar-Ra'y (People of Opinion) and Ahl'al-Hadith (People of tradition), Ilm'al-kalâm ("the science of discourse"), Al-Falasifah (philosophy) and Al-Sûfiyya (sufism), schools of jurisprudence, all are simply the results of the process of systematization of the thought.
The rules of this process are valid both for past and future experiences. But we should accept that Contemporary Muslim Thought has not reached to the stage of "systematization" yet. The thought that has been produced by Muslims in the last century could not still have a "systematic" characteristics. Nonetheless, when we gain a deeper insight to the similar courses of proceeding in history, we can say that it keeps on developing.
