Al-Farabi's Kitab al-Horuf and Meta-Ontology

The parts I & III of Kitab al-Horuf deals with explaining the role of particles in expressing the philosophical notions. This, it seems, is a meta-ontological program that al-Farabi is developing. First, he puts a meta-ontological problem concerning the insufficiency of natural language to express the metaphysical thought especially the being, then he devises a specific logic for being and existents. It is clear that we do need a particular language for metaphysics. He develops this logic, i.e. a special syntax and semantics for metaphysics. He thinks metaphysics deals with meta-categories and if these are to be expressed adequately they must be expressed as particles.
