During the Islamic Golden Age from the 9th to 12th centuries, Muslim philosophers flourished and advanced knowledge in fields like mathematics, medicine, and philosophy. Major figures included Al-Kindi, who introduced Greek philosophy to the Muslim world; Al-Farabi, who wrote on logic, politics, and Plato's ideal state; Avicenna, whose Canon of Medicine was a standard medical text and who distinguished the soul from the body; and Averroes, who argued philosophy and religion could be reconciled and was influential in Western secular thought.
