 At this point (at least in the second edition text) Kant introduces the key claim that judgment is what enables us to distinguish objective connections of representations that necessarily belong together from merely subjective and contingent associations: “[A] judgment is nothing other than the way to bring given cognitions to the objective unity of apperception. That is the aim of the copula is in them: to distinguish the objective unity of given representations from the subjective. For this word designates the relation of the representations to the original apperception and its necessary unity” (B141–142). Kant is speaking here about the mental act of judging that results in the formation of a judgment. Judging is an act of what Kant calls synthesis, which he defines as “the action of putting different representations together with each other and comprehending their manifoldness in one cognition” (A77/B103). In other words, to synthesize is in general to combine several representations into a single (more) complex representation, and to judge is specifically to combine concepts into a judgment – that is, to join a subject concept to a predicate concept by means of the copula, as in “the body is heavy” or “the house is four-sided.” Judgments need not be true, of course, but they always have a truth value (true or false) because they make claims to objective validity. When I say, by contrast, that “If I carry a body, I feel a pressure of weight,” or that “if I see this house, I feel nostalgia,” I am not making a judgment about the object (the body or the house) but rather I am expressing a subjective association that may apply only to me  (B142).[16]
