The Accidents of Being are a special kind of _Inherence_ to the _Substance_ of Being; the _Relational_ kind _par excellence_, as distinguished from the _Qualitative_ kind; which last is denoted by the proper Adjectives. The Oblique Case of a Noun Substantive, whether formed by an Inflexion or by a Preposition, is therefore nothing else than a special kind of Adjective, destitute of the property of Comparison, because it denotes the Accident instead of the Quality of Being, and because Accidents or Relations between Things do not vary by degrees of Intensity as Qualities do. The above description of the Cases of Nouns applies especially to the Oblique Cases; that is to say, to all except the Nominative Case. The Nominative Case is itself susceptible of being regarded as an Accident; but its more important office is that of the SUBJECT of the Proposition, which takes it out of the minor category of an accident, or at least subordinates this latter view of its character. The Accidents of Being in the Universe at large are therefore the analogues of the oblique cases of Nouns Substantive in the Domain of Language; the Nominative Case representing, on the contrary, the central figure in the particular member of discourse, and that which the accidents or _falls_ (_casus_) are perceived to relate to or affect. Substantives and Adjectives were both formerly included under the term Nouns or Names; and we have still to distinguish, when they are under special consideration, as they are here, Nouns Substantive, and Nouns Adjective. By regarding all the Oblique Cases of Nouns Substantive as a species or variety of Nouns Adjective, and so classifying them along with the Adjectives proper, _the Nominative Case_ alone remains to represent _the Substantive_, in the higher and exclusive sense of the term. This is then, at the same time, _The Subject_. The terms employed to designate them sufficiently indicate this identity: _Substantive_, from _sub_, UNDER, and _stans_, STANDING; and _Subject_, from _SUB_, UNDER, and _jectus_, THROWN or CAST. These are, therefore, nearly etymological equivalents. Before passing to the consideration of the Subject and the Proposition, let us finish with the Nouns Adjective, to which we have only given an incidental attention. These are the representatives of Incidence or Attribution; and correspond to the entire adjectivity pertaining to the substantiality of the real or concrete Universe; both Substance and Incidence falling as parts of one domain within the larger domain of RELATION, which in Language is the domain of Grammar proper, including Etymology and Syntax. It may now be shown that this Adjective World is so much a world by itself that Kant's _namings_ for the _four_ groups of the Categories of the Understanding, which we are here enlarging to be the Categories of All Being, are precisely the most appropriate namings for the subdivisions of the Adjective World. These are:
