Grammar of Assent

I have already referred to the faculty of memory in illustration; it will serve me also here. We can form an abstract idea of memory, and call it one faculty, which has for its subject-matter all past facts of our personal experience; but this is really only an illusion; for there is no such gift of universal memory. Of course we all remember in a way, as we reason, in all subject-matters; but I am speaking of remembering rightly, as I spoke of reasoning rightly. In real fact memory, as a talent, is not one indivisible faculty, but a power of retaining and recalling the past in this or that department of our experience, not in any whatever. Two memories, which are both specially retentive, may also be incommensurate. Some men can recite the canto of a poem, or good part of a speech, after once reading it, but have no head for dates. Others have great capacity for the vocabulary of languages, but recollect nothing of the small occurrences of the day or year. Others never forget any statement which they have read, and can give volume and page, but have no memory for faces. I have known those who could, without effort, run through the succession of days on which Easter fell for years back; or could say where they were, or what they were doing, on a given day, in a given year; or could recollect accurately the Christian names of friends and strangers; or could enumerate in exact order the names on all the shops from Hyde Park Corner to the Bank; or had so mastered the University Calender as to be able to bear an examination in the academical history of any M.A. taken at random. And I believe in most of these cases the talent, in its exceptional character, did not extend beyond several classes of subjects. There are a hundred memories, as there are a hundred virtues. Virtue is one indeed in the abstract; but, in fact, gentle and kind natures are not therefore heroic, and prudent and self-controlled minds need not be open-handed. At the utmost such virtue is one only in posse; as developed in the concrete, it takes the shape of species which in no sense imply each other.

So is it with Ratiocination; and as we should betake ourselves to Newton for physical, not for theological conclusions, and to Wellington for his military experience, not for statesmanship, so the maxim holds good generally, "Cuique in arte suâ credendum est:" or, to use the grand words of Aristotle, "We are bound to give heed to the undemonstrated sayings and opinions of the experienced and aged, not less than to demonstrations; because, from their having the eye of experience, they behold the principles of things." [Note 6] Instead of trusting logical science, we must trust persons, namely, those who by long acquaintance with their subject have a right to judge. And if we wish ourselves to share in their convictions and the grounds of them, we must follow their history, and learn as they have learned. We must take up their particular subject as they took it up, beginning at the beginning, give ourselves to it, depend on practice and experience more than on reasoning, and thus gain that mental insight into truth, whatever its subject-matter may be, which our masters have gained before us. By following this course, we may make ourselves of their number, and then we rightly lean upon ourselves, directing ourselves by our own moral or intellectual judgment, not by our skill in argumentation.

This doctrine, stated in substance as above by the great philosopher of antiquity, is more fully expounded in a passage which he elsewhere quotes from Hesiod. "Best of all is he," says that poet, "who is wise by his own wit; next best he who is wise by the wit of others; but whoso is neither able to see, nor willing to hear, he is a good-for-nothing fellow." Judgment then in all concrete matter is the architectonic faculty; and what may be called the Illative Sense, or right judgment in ratiocination, is one branch of it.
