 As remarked above, Aristotle had suggested ([A-SR]: 180b5–7) that insolubles are false simpliciter (absolutely/without qualification), but true secundum quid (in a certain respect). Some authors in the early medieval literature, however, argued that insolubles are without qualification neither true nor false, but only true in a certain respect and false in a certain  respect.[12]  Others used the terminology of simpliciter and secundum quid, but applied it to reference (suppositio) rather than to truth and falsehood, so that in insolubles certain terms did not refer “without qualification” to their referents, but only “in a certain respect”. This view is in effect a kind of restriction on  self-reference.[13]
