Certitude
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.
4.
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, the spiritual, 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.
To this issue indeed we may bring the main difference, viewed philosophically, between nominal Christianity on the one hand, and vital Christianity on the other. Rational, sensible men, as they consider themselves, men who do not comprehend the very notion of loving God above all things, are content with such a measure of probability for the truths of religion, as serves them in their secular transactions; but those who are deliberately staking their all upon the hopes of the next world, think it reasonable, and find it necessary, before starting on their new course, to have some points, clear and immutable, to start from; otherwise, they will not start at all. They ask, as a preliminary condition, to have the ground sure under their feet; they look for more than human reasonings and inferences, for nothing less than the "strong consolation," as the Apostle speaks, of those "immutable things in which it is impossible for God to lie," His counsel and His oath. Christian earnestness may be ruled by the world to be a perverseness or a delusion; but, as long as it exists, it will presuppose certitude as the very life which is to animate it.
This is the true parallel between human and divine knowledge; each of them opens into a large field of mere opinion, but in both the one and the other the primary principles, the general, fundamental, cardinal truths are immutable. In human matters we are guided by probabilities, but, I repeat, they are probabilities founded on certainties. It is on no probability that we are constantly receiving the informations and dictates of sense and memory, of our intellectual instincts, of the moral sense, and of the logical faculty. It is on no probability that we receive the generalizations of science, and the great outlines of history. These are certain truths; and from them each of us forms his own judgments and directs his own course, according to the probabilities which they suggest to him, as the navigator applies his observations and his charts for the determination of his course. Such is the main view to be taken of the separate provinces of probability and certainty in matters of this world; and so, as regards the world invisible and future, we have a direct and conscious knowledge of our Maker, His attributes, His providences, acts, works, and will, from nature, and revelation; and, beyond this knowledge lies the large domain of theology, metaphysics, and ethics, on which it is not allowed to us to advance beyond probabilities, or to attain to more than an opinion.
Such on the whole is the analogy between our knowledge of matters of this world and matters of the world unseen;—indefectible certitude in primary truths, manifold variations of opinion in their application and disposition.
5.
I have said that Certitude, whether in human or divine knowledge, is attainable as regards general and cardinal truths; and that in neither department of knowledge, on the whole, is certitude discredited, lost, or reversed: for, in matter of fact, whether in human or divine, those primary truths have ever kept their place from the time when they first took possession of it. However, there is one obvious objection which may be made to this representation, and I proceed to take notice of it.
