  Except the first work mentioned above which is a free translation and commentary on a discourse by Ibn Sīnā, the other six philosophical treatises represent Khayyam’s own independent philosophical views. It is noteworthy that Khayyam’s philosophical treatises were written in the Peripatetic tradition at a time when philosophy in general and rationalism in particular was under attack by orthodox Muslim jurists—so much that Khayyam had to defend himself against the charge of “being a philosopher.”
