Grammar of Assent
Or again: I depose on my oath in a court of justice, to the best of my knowledge and belief, that I was robbed by the prisoner at the bar. Then, when the real offender is brought before me, I am obliged, to my great confusion, to retract. Because I have been mistaken in my certitude, may I not at least be certain that I have been mistaken? And further, in spite of the shock which that mistake gives me, is it impossible that the sight of the real culprit may give me so luminous a conviction that at length I have got the right man, that, were it decent towards the court, or consistent with self-respect, I may find myself prepared to swear to the identity of the second, as I have already solemnly committed myself to the identity of the first? It is manifest that the two certitudes stand each on its own basis, and the antecedent objection to the admission of a truth which was brought home to me second, drawn from a hallucination which came first, is a mere abstract argument, impotent when directed against good evidence lying in the concrete.

If in the criminal case which I have been supposing, the second certitude, felt by a witness, was a legitimate state of mind, so was the first. An act, viewed in itself, is not wrong, because it is done wrongly. False certitudes are faults because they are false, not because they are (so-called) certitudes. They are, or may be, the attempts and the failures of an intellect insufficiently trained, or off its guard. Assent is an act of the mind, congenial to its nature; and it, as other acts, may be made both when it ought to be made, and when it ought not. It is a free act, a personal act for which the doer is responsible, and the actual mistakes in making it, be they ever so numerous or serious, have no force whatever to prohibit the act itself. We are accustomed in such cases, to appeal to the maxim, “Usum non tollit abusus;” and it is plain that, if what may be called functional disarrangements of the intellect are to be considered fatal to the recognition of the functions themselves, then the mind has no laws whatever and no normal constitution. I just now spoke of the growth of knowledge; there is also a growth in the use of those faculties by which knowledge is acquired. The intellect admits of an education; man is a being of progress; he has to learn how to fulfil his end, and to be what facts show that he is intended to be. His mind is in the first instance in disorder, and runs wild; his faculties have their rudimental and inchoate state, and are gradually carried on by practice and experience to their perfection. No instances then whatever of mistaken certitude are sufficient to constitute a proof, that certitude itself is a perversion or extravagance of his nature.
We do not dispense with clocks, because from time to time they go wrong, and tell untruly. A clock, organically considered, may be perfect, yet it may require regulating. Till that needful work is done, the moment-hand may mark the half-minute, when the minute-hand is at the quarter-past, and the hour hand is just at noon, and the quarter-bell strikes the three-quarters, and the hour-bell strikes four, while the sun-dial precisely tells two o’clock. The sense of certitude may be called the bell of the intellect; and that it strikes when it should not is a proof that the clock is out of order, no proof that the bell will be untrustworthy and useless, when it comes to us adjusted and regulated from the hands of the clock-maker.
Our conscience too may be said to strike the hours, and will strike them wrongly, unless it be duly regulated for the performance of its proper function. It is the loud announcement of the principle of right in the details of conduct, as the sense of certitude is the clear witness to what is true. Both certitude and conscience have a place in the normal condition of the mind. As a human being, I am unable, if I were to try, to live without some kind of conscience; and I am as little able to live without those landmarks of thought which certitude secures for me; still, as the hammer of a clock may tell untruly, so may my conscience and my sense of certitude be attached to mental acts, whether of consent or of assent, which have no claim to be thus sanctioned. Both the moral and the intellectual sanction are liable to be biassed by personal inclinations and motives; both require and admit of discipline; and, as it is no disproof of the authority of conscience that false consciences abound, neither does it destroy the importance and the uses of certitude, because even educated minds, who are earnest in their inquiries after the truth, in many cases remain under the power of prejudice or delusion.
To this deficiency in mental training a wider error is to be attributed,—the mistaking for conviction and certitude states and frames of mind which make no pretence to the fundamental condition on which conviction rests as distinct from assent. The multitude of men confuse together the probable, the possible, and the certain, and apply these terms to doctrines and statements almost at random. They have no clear view what it is they know, what they presume, what they suppose, and what they only assert. They make little distinction between credence, opinion, and profession; at various times they give them all perhaps the name of certitude, and accordingly, when they change their minds, they fancy they have given up points of which they had a true conviction. Or at least bystanders thus speak of them, and the very idea of certitude falls into disrepute.
In this day the subject-matter of thought and belief has so increased upon us, that a far higher mental formation is required than was necessary in times past, and higher than we have actually reached. The whole world is brought to our doors every morning, and our judgment is required upon social concerns, books, persons, parties, creeds, national acts, political principles and measures. We have to form our opinion, make our profession, take our side on a hundred matters on which we have but little right to speak at all. But we do speak, and must speak, upon them, though neither we nor those who hear us are well able to determine what is the real position of our intellect relatively to those many questions, one by one, on which we commit ourselves; and then, since many of these questions change their complexion with the passing hour, and many require elaborate consideration, and many are simply beyond us, it is not wonderful, if, at the end of a few years, we have to revise or to repudiate our conclusions; and then we shall be unfairly said to have changed our certitudes, and shall confirm the doctrine, that, except in abstract truth, no judgment rises higher than probability.
Such are the mistakes about certitude among educated men; and after referring to them, it is scarcely worth while to dwell upon the absurdities and excesses of the rude intellect, as seen in the world at large; as if any one could dream of treating as deliberate assents, as assents upon assents, as convictions or certitudes, the prejudices, credulities, infatuations, superstitions, fanaticisms, the whims and fancies, the sudden irrevocable plunges into the unknown, the obstinate determinations,—the offspring, as they are, of ignorance, wilfulness, cupidity, and pride,—which go so far to make up the history of mankind; yet these are often set down as instances of certitude and of its failure.

I have spoken of certitude as being assigned a definite and fixed place among our mental acts;—it follows upon examination and proof, as the bell sounds the hour, when the hands reach it,—so that no act or state of the intellect is certitude, however it may resemble it, which does not observe this appointed law. This proviso greatly diminishes the catalogue of genuine certitudes. Another restriction is this:—the occasions or subject-matters of certitude are under law also. Putting aside the daily exercise of the senses, the principal subjects in secular knowledge, about which we can be certain, are the truths or facts which are its basis. As to this world, we are certain of the elements of knowledge, whether general, scientific, historical, or such as bear on our daily needs and habits, and relate to ourselves, our homes and families, our friends, neighbourhood, country, and civil state. Beyond these elementary points of knowledge, lies a vast subject-matter of opinion, credence, and belief, viz. the field of public affairs, of social and professional life, of business, of duty, of literature, of taste, nay, of the experimental sciences. On subjects such as these the reasonings and conclusions of mankind vary,—“mundum tradidit disputationi eorum;”—and prudent men in consequence seldom speak confidently, unless they are warranted to do so by genius, great experience, or some special qualification. They determine their judgments by what is probable, what is safe, what promises best, what has verisimilitude, what impresses and sways them. They neither can possess, nor need certitude, nor do they look out for it.
Hence it is that—the province of certitude being so contracted, and that of opinion so large—it is common to call probability the guide of life. This saying, when properly explained, is true; however, we must not suffer ourselves to carry a true maxim to an extreme; it is far from true, if we so hold it as to forget that without first principles there can be no conclusions at all, and that thus probability does in some sense presuppose and require the existence of truths which are certain. Especially is the maxim untrue, in respect to the other great department of knowledge, if taken to support the doctrine, that the first principles and elements of religion, which are universally received, are mere matter of opinion; though in this day, it is too often taken for granted that religion is one of those subjects on which truth cannot be discovered, and on which one conclusion is pretty much on a level with another. But on the contrary, the initial truths of divine knowledge ought to be viewed as parallel to the initial truths of secular: as the latter are certain, so too are the former. I cannot indeed deny that a decent reverence for the Supreme Being, an acquiescence in the claims of Revelation, a general profession of Christian doctrine, and some sort of attendance on sacred ordinances, is in fact all the religion that is usual with even the better sort of men, and that for all this a sufficient basis may certainly be found in probabilities; but if religion is to be devotion, and not a mere matter of sentiment, if it is to be made the ruling principle of our lives, if our actions, one by one, and our daily conduct, are to be consistently directed towards an Invisible Being, we need something higher than a mere balance of arguments to fix and to control our minds. Sacrifice of wealth, name, or position, faith and hope, self-conquest, communion with the spiritual world, presuppose a real hold and habitual intuition of the objects of Revelation, which is certitude under another name.
