The Logic of Hegel

by Georg Wilhelm Friedrich Hegel

(γ) Judgment of Necessity.

177.] The Judgment of Necessity, i.e. of the identity of the content in its difference (1), contains, in the predicate, partly the substance or nature of the subject, the concrete universal, the genus; partly, seeing that this universal also contains the specific character as negative, the predicate represents the exclusive essential character, the species. This is the Categorical judgment.

(2) Conformably to their substantiality, the two terms receive the aspect of independent actuality. Their identity is then inward only; and thus the actuality of the one is at the same time not its own, but the being of the other. This is the Hypothetical judgment.

(3) If, in this self-surrender and self-alienation of the notion, its inner identity is at the same time explicitly put, the universal is the genus which is self-identical in its mutually-exclusive individualities. This judgment, which has this universal for both its terms, the one time as a universal, the other time as the circle of its self-excluding particularisation in which the 'either—or' as much as the 'as well as' stands for the genus, is the Disjunctive judgment. Universality, at first as a genus, and now also as the circuit of its species, is thus described and expressly put as a totality.

The Categorical judgment (such as 'Gold is a metal,' 'The rose is a plant') is the un-mediated judgment of necessity, and finds within the sphere of Essence its parallel in the relation of substance. All things are a Categorical judgment. In other words, they have their substantial nature, forming their fixed and unchangeable substratum. It is only when things are studied from the point of view of their kind, and as with necessity determined by the kind, that the judgment first begins to be real. It betrays a defective logical training to place upon the same level judgments like 'gold is dear,' and judgments like 'gold is a metal.' That 'gold is dear' is a matter of external connexion between it and our wants or inclinations, the costs of obtaining it, and other circumstances. Gold remains the same as it was, though that external reference is altered or removed. Metalleity, on the contrary, constitutes the substantial nature of gold, apart from which it, and all else that is in it, or can be predicated of it, would be unable to subsist. The same is the case if we say, 'Caius is a man.' We express by that, that whatever else he may be, has worth and meaning, only when it corresponds to his substantial nature or manhood.

But even the Categorical judgment is to a certain extent defective. It fails to give due place to the function or element of particularity. Thus 'gold is a metal,' it is true; but so are silver, copper, iron: and metalleity as such has no leanings to any of its particular species. In these circumstances we must advance from the Categorical to the Hypothetical judgment, which may be expressed in the formula: If A is, B is. The present case exhibits the same advance as formerly took place from the relation of substance to the relation of cause. In the Hypothetical judgment the specific character of the content shows itself mediated and dependent on something else: and this is exactly the relation of cause and effect. And if we were to give a general interpretation to the Hypothetical judgment, we should say that it expressly realises the universal in its particularising. This brings us to the third form of the Judgment of Necessity, the Disjunctive judgment. A is either B or C or D. A work of poetic art is either epic or lyric or dramatic. Colour is either yellow or blue or red. The two terms in the Disjunctive judgment are identical. The genus is the sum total of the species, and the sum total of the species is the genus. This unity of the universal and the particular is the notion: and it is the notion which, as we now see, forms the content of the judgment.

(δ) Judgment of the Notion.

178.] The Judgment of the Notion has for its content the notion, the totality in simple form, the universal with its complete speciality. The subject is, (1) in the first place, an individual, which has for its predicate the reflection of the particular existence on its universal; or the judgment states the agreement or disagreement of these two aspects. That is, the predicate is such a term as good, true, correct. This is the Assertory judgment.

Judgments, such as whether an object, action, &c. is good, bad, true, beautiful, &c., are those to which even ordinary language first applies the name of judgment. We should never ascribe judgment to a person who framed positive or negative judgments like, This rose is red, This picture is red, green, dusty, &c.

The Assertory judgment, although rejected by society as out of place when it claims authority on its own showing, has however been made the single and all-essential form of doctrine, even in philosophy, through the influence of the principle of immediate knowledge and faith. In the so-called philosophic works which maintain this principle, we may read hundreds and hundreds of assertions about reason, knowledge, thought, &c. which, now that external authority counts for little, seek to accredit themselves by an endless restatement of the same thesis.
