 Al-Jadīd fī ‘l-ḥikma (The New Wisdom); is a comprehensive exposition of thirteenth century science and philosophy. (For a preliminary study, see Langemann 2005; the titles of this book are discussed in the final sections below.)  Numerous manuscript copies exist (Pourjavady &amp; Schmidtke 2006, 87–92). Ibn Kammuna experimented with different formats and especially different lengths in his philosophical writing. He adhered to the traditional tri-partite classification of logic, physics, and metaphysics, in a lengthy format (al-Jadīd), a highly condensed version (Talkhīṣ; see Pourjavady &amp; Schmidtke 2006, 94, for bibliography, and an edition of the Arabic text, 196–206), and quite likely a middle length version (Risala fī ‘l-ḥikma), whose authenticity is still unresolved (Langermann 2005, 279–286).
