In this short work, the first of its kind in the English language, an attempt has been made to give reliable definitions and clear explanations of the major terms used by the medieval Muslim philosophers in logic, metaphysics, psychology and other allied disciplines.
Some important terms selected have been added variants of Arabicised Greek names and titles which though commonly found in such source books as Ibn al-Nadim’s al-Fihrist, al-Qifti’s Tarikh al-Hukama’ Ibn abi ‘Usaibi’ah’s Uyun al-Anba’ Tabaqat al’Atibba’, are yet likely to be unfamiliar to the modern reader. All terms given in Arabic script with transliteration in English have been arranged alphabetically.
