Now the same sentiment may be expressed by the comparative; but then the Athenians and Socrates, though belonging to one species, are conceived as mutually opposed, and referred to different places, whereas the superlative refers them to one common aggregate. Thus, if we employ the comparative, we say, “Socrates was wiser than any other Athenian.”
Agreeably to the observation now made, we cannot say, “Cicero was more eloquent than the Romans,” or “than any Roman;” because Cicero was himself a Roman, one of the class with which he is compared, and could not therefore be more eloquent than himself. As the objects compared belong, therefore, to one class, and are not two individuals, nor two aggregates, the comparative cannot be employed, unless by placing them in opposition, or referring them to different places, as, “Cicero was more eloquent than any other Roman.” Here the word other denotes that opposition, that diversity of place or species, which, in all cases but the one already mentioned, is essentially implied in the use of the comparative.
I have observed already, that when the superlative is employed, the things compared are referred to one aggregate; and that when the comparative is used, they are contradistinguished by a different reference. This distinction obtains uniformly, unless when we compare only two individuals, or two classes, both referred to one aggregate, as “the elder of the Catos,” “of these two nations (speaking of the Greeks and Romans), the latter were the more warlike.” In such examples as these, the comparative, while it retains its own distinctive character, denoting simple excess, partakes also of the nature of the superlative, the objects compared being referred by the preposition to one and the same aggregate. But as the superlative is always followed by of, and the comparative, in every case except the one now mentioned, followed by than, some writers say, “the eldest of the two,” “the latter were the most warlike.” This phraseology, however conformable to the generally distinguished usage of the comparative and superlative, is repugnant to the characteristic power of these degrees, by which one denotes simple excess, while the other heightens or lessens the quality to its highest or lowest degree.
From the preceding remarks will appear the impropriety of saying, “Jacob loved Joseph more than all his children.”[38] Joseph being one of his children, the sentiment expressed involves an absurdity: it should be “more than all his other children.” “In the beginning of the 16th century, Spain is said to have possessed a thousand merchant ships, a number probably far superior to that of any nation in Europe in that age.” (Robertson’s America.) It should be, “that of any other nation in Europe:” for, Spain being one of the European nations, she could not possess a number superior to her own. The comparative required the terms to be contrasted by the word other.
“Adam
The comeliest of men since born
His sons. The fairest of her daughters Eve.”—Milton.
“Adam,” the antecedent subject of comparison, is here improperly referred to the aggregate of “men since born.” To this aggregate he cannot be said to belong, not having been “born,” nor being reducible to the class of “his own sons.” Eve also is referred to a species of which she was no part. In neither of these comparisons can the second term include the first; yet the preposition refers them to one class. Such phraseologies as these, though not ungrammatical, involve an absurdity, and should therefore be dismissed.
Adjectives, whose signification does not admit intension or remission, cannot be compared. Among these are to be reckoned, 1st, All words expressive of figure, as circular, square, triangular, perpendicular, straight; for it is obvious, that if a body or figure be triangular, or square, or circular, it cannot be more or less so. It is either circular, or not circular; triangular, or not triangular; straight, or not straight. If the affirmative be the case, gradation from more or less, or conversely, is impossible; if the negative be true, then the attributes denoted by these adjectives do not belong to it; and therefore the epithets circular, triangular, straight, &c., are inapplicable. Hence such expressions as these, “place the staff more erect,” “make the field more triangular,” are highly improper. We should say, “set the staff erect,” “make the field triangular.”
2dly. All adjectives whose signification, in their simple form, implies the highest or lowest possible degree, admit not comparison, as, chief, supreme, universal, perfect, extreme, &c. Hume, speaking of enthusiasm, says (Essays, vol. i. p. 72), “it begets the most extreme resolutions.” Extreme implies the farthest, or the greatest possible, and cannot admit intension.
