What to read after Al-Kindi?

Al-Kindi is believed by many scholars to be the first Islamic philosopher. At a time when Europe was plunged into the Dark Ages, the Islamic world was experiencing an important time of cultural growth and scientific advancement. While many considered Muslim students of ancient Greek philosophers to be infidels, al-Kindi was able to master the scholarship while interpreting it through his Muslim faith. His conclusions always supported the teachings of Islam, but the methods that he drew upon to reach these conclusions were rooted in science, math, and principles accepted by many other cultures and faiths.
