Râzî was clear that he did not intend the essentialist reading to amount to an ampliation of the subject term to the possible such as he attributed to Alfarabi (“Alfarabi claimed that with respect to ‘every J’ one shouldn't [only] take account of actually occurring Js, but everything whose description as J is possible”; Râzî Mulakhkhas [2002] 142.4–5).  But with the phrase “were it to exist externally it would be true of it that it is J”, Râzî posited a domain of discourse including non-instantiated Js, and he seemed to take his propositions thereby to refer to possible-Js.
