This understanding of the intellect was also very influential for Al-Farabi, Avicenna, and Averroes, and "virtually all Islamic and Jewish philosophers".[38] On the other hand, concerning the active intellect, like Alexander and Plotinus, he saw this as a transcendent being existing above and outside man. Differently from Alexander, he did not equate this being with the first cause of the Universe itself, but something lower.[39] However he equated it with Plato's Idea of the Good.[40]
