Abu Sulayman Sijistani

Abu Sulayman Muhammad Sijistani, (Persian: ابوسلیمان سجستانی‎‎) also called al-Mantiqi (the Logician) (c. 932 – c. 1000 CE), named for his origins in Sijistan or Sistan province in present-day Iran, became the leading philosopher of Islamic humanism in the Baghdad of his time.

Deeply religious, he regarded both religion and philosophy as valid and true; but separate, concerned with different issues, and proceeding by different means. He thus rejected the claims of the theologians employing Ilm al-Kalam to have built a theology "proved" by rationality and of the Brethren of Purity to offer a synthesis of philosophy and religion.

His best-known work is Siwān al-Ḥikma "Vessel of Wisdom", a history of philosophy from the beginning to his own time.
