What Objective Unity of Self-consciousness is.SS 14It is by means of the transcendental unity of apperception that all the manifold, given in an intuition is united into a conception of the object.On this account it is called objective, and must be distinguished from the subjective unity of consciousness, which is a determination of the internal sense, by means of which the said manifold in intuition is given empirically to be so united.Whether I can be empirically conscious of the manifold as coexistent or as successive, depends upon circumstances, or empirical conditions.Hence the empirical unity of consciousness by means of association of representations, itself relates to a phenomenal world and is wholly contingent.On the contrary, the pure form of intuition in time, merely as an intuition, which contains a given manifold, is subject to the original unity of consciousness, and that solely by means of the necessary relation of the manifold in intuition to the "I think,"consequently by means of the pure synthesis of the understanding, which lies a priori at the foundation of all empirical synthesis.
The transcendental unity of apperception is alone objectively valid;the empirical which we do not consider in this essay, and which is merely a unity deduced from the former under given conditions in concreto, possesses only subjective validity.One person connects the notion conveyed in a word with one thing, another with another thing; and the unity of consciousness in that which is empirical, is, in relation to that which is given by experience, not necessarily and universally valid.
The Logical Form of all Judgements consists in the Objective Unity of Apperception of the Conceptions contained therein.SS 15I could never satisfy myself with the definition which logicians give of a judgement.It is, according to them, the representation of a relation between two conceptions.I shall not dwell here on the faultiness of this definition, in that it suits only for categorical and not for hypothetical or disjunctive judgements, these latter containing a relation not of conceptions but of judgements themselves-a blunder from which many evil results have followed.* It is more important for our present purpose to observe, that this definition does not determine in what the said relation consists.
*The tedious doctrine of the four syllogistic figures concerns only categorical syllogisms; and although it is nothing more than an artifice by surreptitiously introducing immediate conclusions (consequentiae immediatae) among the premises of a pure syllogism, to give ism' give rise to an appearance of more modes of drawing a conclusion than that in the first figure, the artifice would not have had much success, had not its authors succeeded in bringing categorical judgements into exclusive respect, as those to which all others must be referred- a doctrine, however, which, according to SS5, is utterly false.
But if I investigate more closely the relation of given cognitions in every judgement, and distinguish it, as belonging to the understanding, from the relation which is produced according to laws of the reproductive imagination (which has only subjective validity), I find that judgement is nothing but the mode of bringing given cognitions under the objective unit of apperception.This is plain from our use of the term of relation is in judgements, in order to distinguish the objective unity of given representations from the subjective unity.For this term indicates the relation of these representations to the original apperception, and also their necessary unity, even although the judgement is empirical, therefore contingent, as in the judgement: "All bodies are heavy." I do not mean by this, that these representations do necessarily belong to each other in empirical intuition, but that by means of the necessary unity of appreciation they belong to each other in the synthesis of intuitions, that is to say, they belong to each other according to principles of the objective determination of all our representations, in so far as cognition can arise from them, these principles being all deduced from the main principle of the transcendental unity of apperception.In this way alone can there arise from this relation a judgement, that is, a relation which has objective validity, and is perfectly distinct from that relation of the very same representations which has only subjective validity- a relation, to wit, which is produced according to laws of association.According to these laws, I could only say:
"When I hold in my hand or carry a body, I feel an impression of weight"; but I could not say: "It, the body, is heavy"; for this is tantamount to saying both these representations are conjoined in the object, that is, without distinction as to the condition of the subject, and do not merely stand together in my perception, however frequently the perceptive act may be repeated.
