al-Fārābī, Abu Nasr Muḥammad Iḅn Tarkhān
He reconciled the various modes of human reflection and enquiry by dividing the intellect (the extension of Being into the human) into three: the active intellect, the potential intellect and the acquired intellect. In this way he could affirm the equal validity of many human arts and skills. His Kitāb al-Musiqa (The Book of Music) laid the foundations for an Islamic theory of music, drawing attention to relations between mathematics and music; and his Risalah fi araʾ ahl al Madina al-fadilah (Treatise on the … Virtuous City) was widely influential in the development of political science.
