its predicate cannot refer to a part of that which is contained in the

conception of the subject and be excluded from the rest。 The predicate

is valid for the whole conception just as if it were a general

conception; and had extent; to the whole of which the predicate

applied。 On the other hand; let us compare a singular with a general

judgement; merely as a cognition; in regard to quantity。 The

singular judgement relates to the general one; as unity to infinity;

and is therefore in itself essentially different。 Thus; if we estimate

a singular judgement (judicium singulare) not merely according to

its intrinsic validity as a judgement; but also as a cognition

generally; according to its quantity in comparison with that of

other cognitions; it is then entirely different from a general

judgement (judicium commune); and in a complete table of the momenta

of thought deserves a separate place… though; indeed; this would not

be necessary in a logic limited merely to the consideration of the use

of judgements in reference to each other。

  2。 In like manner; in transcendental logic; infinite must be

distinguished from affirmative judgements; although in general logic

they are rightly enough classed under affirmative。 General logic

abstracts all content of the predicate (though it be negative); and

only considers whether the said predicate be affirmed or denied of the

subject。 But transcendental logic considers also the worth or

content of this logical affirmation… an affirmation by means of a

merely negative predicate; and inquires how much the sum total of

our cognition gains by this affirmation。 For example; if I say of

the soul; 〃It is not mortal〃… by this negative judgement I should at

least ward off error。 Now; by the proposition; 〃The soul is not

mortal;〃 I have; in respect of the logical form; really affirmed;

inasmuch as I thereby place the soul in the unlimited sphere of

immortal beings。 Now; because of the whole sphere of possible

existences; the mortal occupies one part; and the immortal the

other; neither more nor less is affirmed by the proposition than

that the soul is one among the infinite multitude of things which

remain over; when I take away the whole mortal part。 But by this

proceeding we accomplish only this much; that the infinite sphere of

all possible existences is in so far limited that the mortal is

excluded from it; and the soul is placed in the remaining part of

the extent of this sphere。 But this part remains; notwithstanding this

exception; infinite; and more and more parts may be taken away from

the whole sphere; without in the slightest degree thereby augmenting

or affirmatively determining our conception of the soul。 These

judgements; therefore; infinite in respect of their logical extent;

are; in respect of the content of their cognition; merely

limitative; and are consequently entitled to a place in our

transcendental table of all the momenta of thought in judgements;

because the function of the understanding exercised by them may

perhaps be of importance in the field of its pure a priori cognition。

  3。 All relations of thought in judgements are those (a) of the

predicate to the subject; (b) of the principle to its consequence; (c)

of the divided cognition and all the members of the division to each

other。 In the first of these three classes; we consider only two

conceptions; in the second; two judgements; in the third; several

judgements in relation to each other。 The hypothetical proposition;

〃If perfect justice exists; the obstinately wicked are punished;〃

contains properly the relation to each other of two propositions;

namely; 〃Perfect justice exists;〃 and 〃The obstinately wicked are

punished。〃 Whether these propositions are in themselves true is a

question not here decided。 Nothing is cogitated by means of this

judgement except a certain consequence。 Finally; the disjunctive

judgement contains a relation of two or more propositions to each

other… a relation not of consequence; but of logical opposition; in so

far as the sphere of the one proposition excludes that of the other。

But it contains at the same time a relation of community; in so far as

all the propositions taken together fill up the sphere of the

cognition。 The disjunctive judgement contains; therefore; the relation

of the parts of the whole sphere of a cognition; since the sphere of

each part is a complemental part of the sphere of the other; each

contributing to form the sum total of the divided cognition。 Take; for

example; the proposition; 〃The world exists either through blind

chance; or through internal necessity; or through an external

cause。〃 Each of these propositions embraces a part of the sphere of

our possible cognition as to the existence of a world; all of them

taken together; the whole sphere。 To take the cognition out of one

of these spheres; is equivalent to placing it in one of the others;

and; on the other hand; to place it in one sphere is equivalent to

taking it out of the rest。 There is; therefore; in a disjunctive

judgement a certain community of cognitions; which consists in this;

that they mutually exclude each other; yet thereby determine; as a

whole; the true cognition; inasmuch as; taken together; they make up

the complete content of a particular given cognition。 And this is

all that I find necessary; for the sake of what follows; to remark

in this place。

  4。 The modality of judgements is a quite peculiar function; with

this distinguishing characteristic; that it contributes nothing to the

content of a judgement (for besides quantity; quality; and relation;

there is nothing more that constitutes the content of a judgement);

but concerns itself only with the value of the copula in relation to

thought in general。 Problematical judgements are those in which the

affirmation or negation is accepted as merely possible (ad libitum)。

In the assertorical; we regard the proposition as real (true); in

the apodeictical; we look on it as necessary。* Thus the two judgements

(antecedens et consequens); the relation of which constitutes a

hypothetical judgement; likewise those (the members of the division)

in whose reciprocity the disjunctive consists; are only problematical。

In the example above given the proposition; 〃There exists perfect

justice;〃 is not stated assertorically; but as an ad libitum

judgement; which someone may choose to adopt; and the consequence

alone is assertorical。 Hence such judgements may be obviously false;

and yet; taken problematically; be conditions of our cognition of

the truth。 Thus the proposition; 〃The world exists only by blind

chance;〃 is in the disjunctive judgement of problematical import only:

that is to say; one may accept it for the moment; and it helps us

(like the indication of the wrong road among all the roads that one

can take) to find out the true proposition。 The problematical

proposition is; therefore; that which expresses only logical

possibility (which is not obje
