 There is one part of the regime of primary concepts that al-Fārābī never suggests that language should replicate. Some concepts are more inclusive than others; for example, “animal” is more inclusive than “human”. Following one reading of Aristotle, al-Fārābī believes that there are ten maximally inclusive simple primary concepts (ignoring “thing”, “concept”, “one”, and “being” which include all concepts). He refers to these ten concepts as “categories” (maqūlāt, not to be confused with ma‘qūlāt above). But we will prefer to call them by their alternative name “supreme genera”, because al-Fārābī confusingly also applies the name “category” to all simple primary concepts. Languages do distinguish the minimally inclusive concepts, those that apply to just one thing, by using proper names for them. But it’s unrealistic to expect languages to copy the rest of this regime of inclusions, and we know of no place where al-Fārābī suggests that it should.
