Note 107 — Chapter XI

امكان imkan, “possibility,” signifies that, the existence or non-existence of which, is the necessary consequence of the essence of a thing. The philosophers distinguish by name four sorts of possibility: 1. imkan zati, “possibility with respect to essence;” 2. imkan istidadi, “possibility by disposition,” also called mokúni, “eventual;” 3. imkan khaz, “special possibility;” and 4. imkan âam, “general possibility.”—(See on this subject Jorjani’s Definitions, Notices et Extraits des MSS., vol.
