c. It is the synthesis of ideas into unity and consciousness of their
objective validity, not in the sense of agreement with external reality but in the sense of the logical necessity of their synthesis (Sigwart).
d. It is the analysis of an aggregate idea (_Gesammtvorstellung_) into subject and predicate; based on a previous association of ideas, on relating and comparing, and on the apperceptive synthesis of an aggregate idea in consequence; but itself consisting in an apperceptive analysis of that aggregate idea; and requiring will in the form of apperception or attention (Wundt).
e. It requires an idea, because every object is conceived as well as recognized or denied; but it is itself an assertion of actual fact, every perception counts for a judgment, and every categorical is changeable into an existential judgment without change of sense (Brentano, who derives his theory from Mill except that he denies the necessity of a combination of ideas, and reduces a categorical to an existential judgment).
f. It is a decision of the validity of an idea requiring will (Bergmann, following Brentano).
g. Judgment (_Urtheil_) expresses that two ideas belong together: "by-judgment" (_Beurtheilung_) is the reaction of will expressing the validity or invalidity of the combination of ideas (Windelband, following Bergmann, but distinguishing the decision of validity from the judgment).
h. Judgment is consciousness of the identity or difference and of the causal relations of the given; naming the actual combinations of the data, but also requiring a priori categories of the understanding, the notions of identity, difference and causality, as principles of thought or laws, to combine the plurality of the given into a unity (Schuppe).
