 The primacy of being (everything that is conceived of “is”) leads to an often unseen consequence: everything that is conceived of or simply mentally represented exists and hence has at least a mental existence (which means either intellectual or imaginary or estimative). Indeed, the existent as such is immaterial and only non-existence in the absolute sense does (obviously) not exist, since it cannot be either conceived or discussed (Ilāhiyyāt, I, 5, 32, 6–16). Non-existent things are only relatively non-existent: resurrection, e.g., and possible and imaginary entities exist at least in the mind (Ilāhiyyāt, I, 5, 33, 12–34, 9; cf. Arist., Metaph., 1006b10). Impossible things seem to be non-existent insofar as they are not properly conceived (intellectual existence is distinct from imaginative existence: Michot 1987; Black 1997, 1999).
