What indeed can seem more simply true than the admission of a fact? Yet facts are often inspissated theories, while many theories are merely explained facts. One of the greatest authorities on Inductive Philosophy writes thus (Whewell's Philosophy of the Inductive Sciences. Ed. 2. Vol. I. p. 45)—"We are often told that such a thing is a Fact; A Fact and not a Theory, with all the emphasis which, in speaking or writing, tone or italics or capitals can give. We see from what has been said, that when this is urged, before we can estimate the truth, or the value of the assertion, we must ask to whom is it a Fact? what habits of thought, what previous information, what Ideas does it imply, to conceive the Fact as a Fact? Does not the apprehension of the Fact imply assumptions which may with equal justice be called Theory and which are perhaps false Theory? in which case, the Fact is no Fact. Did not the ancients assert it as a Fact, that the earth stood still, and the stars moved? and can any Fact have stronger apparent evidence to justify persons in asserting it emphatically than this had?"
The generality of English jurymen might be expected to give an affirmative verdict. For have they not seen with their own eyes the Sun rise up in the East, ascend to the top of the sky, and go down in the West? And is not seeing, believing?
The question, what elements are required to yield the product of trustworthy perception, phenomenon, or fact, is investigated by Dr. Whewell through several pages preceding the one from which we have quoted. After discussing it at length, he writes (p. 42): "And thus, we have an intelligible distinction of Fact and Theory, if we consider Theory as a conscious, and Fact as an unconscious inference, from the phenomena which are presented to our senses."
The subject is in itself so singularly interesting that a few more extracts are added in our Additional Notes.[y] Let the reader, while perusing them, remember that Idealism once so sovereign in its empire, is only the other pole of a line of thought which just now happens to be in the ascendant. Both poles strongly resemble half-truths. And what is more delusive in evidence than a half-truth, or more perilously sophisticating to the mind of him who utters it?
The thorough-paced Idealist deals with the presentations of his inner consciousness, precisely as the Positivist deals with the presentations of his outer senses. They are his phenomena, his facts. Beyond the circumstances of their inward occurrence and succession he knows and can know nothing. You may arrange them into series of antecedents and consequents,—and then the observation becomes a law,—a law of association, uniform order, or necessary connection: whichever you may choose to call it. In one respect, he has an advantage over the Positivist. No thinker equidistant from both, is likely to deny that primary facts are for every man, the phenomena most immediately apparent to his own consciousness.
Amongst ordinary men, however, the reasoning Idealist seldom appears; the Idealist in feeling and temper is by no means rare. A man weary and worn by sorrow or old age, thinks and speaks of his life as very like a dream. And numbers who have exhausted the strength of self-controlling will, loiter along their way, regardless whether a moving panorama on each hand is or is not, an unreality. Like travel-tired travellers down the Danube, or the Rhine, they interweave scenes bright and dark, as they float by, in one endless train of dimly felt reverie.
The same characteristic holds good in regard to many a Positivist. Very few people have ever examined those iron wheels, on which the conclusions of Positively-inclined writers seem to run so rapidly. They may be flawed—they may be true—hardly any one has thought of sounding them. But common life has its Positivism, as well as its Chemistry; and the Positivism of common life is everywhere. It saves labour,—you may take facts as you find them. It troubles no one,—a Pyrrhonic posture is the easiest of attitudes. It frees busy people from moral anxieties, ideal terrors, the shadows of futurity. In short, to men of the world it is neither more nor less than Indifferentism.
The comparison between these two Nihilistic tendencies might be pushed farther, but it has been carried far enough for our purpose. Both sorts, when viewed as principles of practical life, coincide in yielding the conclusion we now wish to deduce. It is folly to be deterred from the pursuit of ultimate truth, by any amount of speculative difficulty whatsoever. And the reason is plain. Practical truths—the beliefs which affect our hearts and lives—are always ultimate truths. To give them up, is to give up our highest and best,—perhaps our all. It is worse than useless to quail before intellectual obstacles. The Difficult soon begins to appear the Impossible.
