The Theory of Moral Sentiments - Adam Smith [236]
It is, perhaps, worth while to observe that those prepositions, which in modern languages hold the place of the ancient cases, are, of all others, the most general, and abstract, and metaphysical; and of consequence, would probably be the last invented. Ask any man of common acuteness, What relation is expressed by the preposition above? He will readily answer, that of superiority . By the preposition below? He will as quickly reply, that of inferiority. But ask him, what relation is expressed by the preposition of, and, if he has not beforehand employed his thoughts a good deal upon these subjects, you may safely allow him a week to consider of his answer. The prepositions above and below do not denote any of the relations expressed by the cases in the ancient languages. But the preposition of, denotes the same relation, which is in them expressed by the genitive case; and which, it is easy to observe, is of a very metaphysical nature. The preposition of, denotes relation in general, considered in concrete with the co-relative object. It marks that the noun substantive which goes before it, is somehow or other related to that which comes after it, but without in any respect ascertaining, as is done by the preposition above, what is the peculiar nature of that relation. We often apply it, therefore, to express the most opposite relations; because, the most opposite relations agree so far that each of them comprehends in it the general idea or nature of a relation. We say, the father of the son, and the son of the father; the fir-trees of the forest, and the forest of the fir-trees. The relation in which the father stands to the son, is, it is evident, a quite opposite relation to that in which the son stands to the father; that in which the parts stand to the whole, is quite opposite to that in which the whole stands to the parts. The word of, however, serves very well to denote all those relations, because in itself it denotes no particular relation, but only relation in general; and so far as any particular relation is collected from such expressions, it is inferred by the mind, not from the preposition itself, but from the nature and arrangement of the substantives, between which the preposition is placed.
What I have said concerning the preposition of, may in some measure be applied to the prepositions to, for, with, by, and to whatever other prepositions are made use of in modern languages, to supply the place of the ancient cases. They all of them express very abstract and metaphysical relations, which any man, who takes the trouble to try it, will find it extremely difficult to express by nouns substantive, in the same manner as we may express the relation denoted by the preposition above, by the noun substantive superiority. They all of them, however, express some specific relation, and are, consequently, none of them so abstract as the preposition of, which may be regarded as by far the most metaphysical of all prepositions. The prepositions, therefore, which are capable of supplying the place of the ancient cases, being more abstract than the other prepositions, would naturally be of more difficult invention. The relations at the same time which those prepositions express, are, of all others, those which we have most frequent occasion to mention. The prepositions above, below, near, within, without, against, &c. are much more rarely made use of, in modern languages, than the prepositions of, to, for, with, from, by. A preposition of the former kind will not occur twice in a page; we can scarce compose a single sentence without the assistance of one or two of the latter. If these latter prepositions, therefore, which supply
