The act of judgment accordingly brings with it the further reflection whether this or that predicate which is in someone's head can and should be attached to the subject matter that exists outside it on its own; the judgment itself is simply the act that combines the predicate with the subject, so that, if this combination did not occur, the subject and predicate would still each remain what it is, the one concretely existing as thing in itself, the other as a representation in someone's head.
