 At no point does al-Ghazâlî reveal the philosophical origins of his ethics. He himself saw a close connection between the ethics of the falâsifa and Sufi notions of an ascetic and virtuous lifestyle. In his Revival he merges these two ethical traditions to a successful and influential fusion. In his autobiography al-Ghazâlî says that the ethics of the falâsifa and that of the Sufis are one and the same. Congruent with his position that many teachings and arguments of the falâsifa are taken from earlier revelations and from the divinely inspired insights of mystics, who existed already in pre-Islamic religions (Treiger 2012, 99–101) he adds that the falâsifa have taken their ethics from the Sufis, meaning here mystics among the earlier religions (al-Ghazâlî 1959a, 24 = 2000b, 67).
