We may use Nishida's own terms to explain his second concern, the way that objects ordinarily function in judgments. In what Nishida alternatively called the logic of objects or subjective logic, objects of consciousness are made the subject of propositions or judgments, and are specified by predicating properties of the (grammatical) subject. Eventually a subject is reached that cannot itself be predicated of anything else, recalling Aristotle's hypokeimenon or individual substance that can be subject but never predicate.
