The Question of Art in Islamic Thought

One of the main questions concerning the status of art in Islam is whether there is a knowledge or thinking in Islam as the origion of the works of art. In other words¡ is there any artistic vision in Islamic thought? If the answer to this question is negative¡ what can be said of the masterpieces of art from architecture to calligraphy in the world of Islam? However¡ if the answer is positive¡ there are following ambiguities which should be removed.
1. True religious knowledge in Islam should be distinguished from the dogmatic Islamic ideology.
2. The traditional concept of art in Islam should be discerned and be differentiated from the new concept of art in the realm of aesthetics.
