On the other hand, it is a poor science that has nothing to offer but an eternal query for the truth. A poor science, that with self-consciousness promises enlightenment and what not, but finally can give nothing but ceaseless doubt instead of truth, tormenting darkness instead of cheerful light. Why, then, research where nothing can be found? Why raise searching eyes to the sky when the stars do not show themselves? What kind of progress is this when science does nothing further than dig forever at the foundation? The great St. Augustine has long also passed judgment on this kind of science: “Such doubting is abhorred by the City of God as false wisdom, because among the things which we grasp with our intellect and reason there is a knowledge, limited, it is true, because the soul is weighed down by a perishable body, as the Apostle says: ex parte scimus—but which has full certainty” (De Civitate Dei, XIX, 18).
An Erroneous Supposition.
The errors just dealt with, and the demand that scientific research must doubt everything, is based on a supposition often stated expressly as a principle, and which appears quite plausible even to a mind not trained in philosophy. It says: There is but one certainty, the scientific certainty; the certain possession of the truth can be obtained only by scientific research. To rid the world of error, we are told, “there is but one way, viz., scientific work. Only science and scientific truth are able to dispose of error” (Th. Lipps, Allgemeine Zeitung, Muenchen, [pg 136] August 4, 1908). “Truth is scientific truth, based on criticism, hence the religion of modern man must also rest on critical truth.... There is no other authority but science” (Masaryk, Kampf um die Religion, 13).
This sort of speech we hear from the college chair as the slogan for education and enlightenment: any one deficient in science or in education belongs more or less to the unthinking mass who have no convictions of their own, but submit blindly to impressions and authority.
Such unclarified conceptions, with their inferences, are even met with where they would not be expected, for instance, we read: “What the average individual needed was a good shepherd, a shepherd's devotion and love, that uplifts and urges onward; it was authority, Church-ministry and care of souls, that was needed. The Church is an organized pastorate, for the average individual likes to go with the flock. The chosen are they who feel within themselves the great question of truth as the care of their heart and task of their life, who experience its tremendous tension, and who are struggling to the end with the intellectual battles provoked by this question of truth. The average people, i.e., the many, the great majority, need something steady to which they can cling—persons and teachers, laws and practice.” And why this uncharitable distinction between people belonging to the flock and the chosen ones, as if the Church and its ecclesiastical functions were only appointed for the former? Particularly because “without methodical scientific work man cannot attain to the truth” (H. Schell, Christus, 1900, 125, 64).
Thus science may summon everything before its forum, no one having a right to interfere; in the superiority bestowed by the right of autocracy it may sweep aside everything that is opposed to it, no matter by what authority. Hence science must be free to jolt everything, free to question the truth of everything, which it has not itself examined and approved. This is the fundamental supposition of modern freedom of science; also a fatal error, betraying a woeful ignorance of the construction of the human intellect, in spite of all its pretentiousness. As a rule we have a true certainty in most matters, particularly in philosophical-religious convictions, a certainty not gained by scientific studies; by aid of the latter we may explain or strengthen that certainty, but we are not free to upset it.
We cannot avoid examining this point a little closer. There is a twofold certainty, one, which we shall call the natural certainty, [pg 137] is a firm conviction based on positive knowledge, but without a clear reflexive consciousness of the grounds on which the conviction is actually resting. Reason recognizes these grounds, but the recognition is not distinct enough for reason to become conscious of them, to be able to state them accurately and in scientific formulas. scientific certainty is a firm conviction, with a clear consciousness of the grounds, hence it can easily account for them. Natural certainty is the usual one in human life; scientific certainty is the privilege of but a few, and even they have it in but very few things.
Everybody has a positive intellectual certainty that a complicated order cannot be the result of accident, and that for every event there must be a cause, though not every one will be able readily to demonstrate the truth of his certainty. But if the philosopher should look for the proof, he would do so in no other way than by reflecting upon his natural and direct knowledge, and by trying to become conscious of what he has thus directly found out. To illustrate by a few examples: We are all convinced of the existence of an exterior world, and any one who is not an idealist will call this conviction a reasonable certainty, and yet only a few will be able to answer the subtle questions of a sceptic. This certainty again is a natural but not a scientific one. How difficult it is here also for reason to attain scientific certainty, how easy it is to go astray in these researches, is proved by the errors of idealism so incomprehensible to the untrained natural mind. Let us ask, finally, any one: Why must we say: “Cæsar defeated Pompey,” but not “Cæsar defeated of Pompey”? He will tell us this is nonsense; maybe he will add that the genitive has another meaning. But should I ask further how the meaning of the genitive differs from that of the accusative, as both cases seem to have often the same meaning, I shall get no answer. There is a certitude, but only a natural one. Even if I should ask modern students of the psychology and history of languages, like Wundt, Paul, or whatever their names may be, I should not get a satisfactory answer either. The whole logic of language, with its subtle forms and moods of expression—how difficult for scientific research! And yet the mind of even a child penetrates it, and not only a European child, but the Patagonian and negro child, who is able to master by its intellectual power complex languages, with four numbers, many moods, fourteen tenses, etc.
These examples will suffice, though volumes of them could be written. They show us clearly a twofold certainty. The difference between the natural and scientific certainty is not that the former is a blind conviction formed at random, but only that one is not clearly conscious of the reasons on which it rests, whereas this is the case in scientific certitude. We see further the untrained power of the intellect manifest itself in natural knowledge and certainty; for this purpose it is primarily created; philosophical thought is difficult for it, and many [pg 138]have no talent at all for it. It is also unfailing in apprehending directly things pertaining to human life. Here the mind is free of that morbid scepticism of which it too easily becomes a prey when it begins to investigate and probe scientifically. What it there sees with certainty cannot always be found here distinctly, and thus the mind begins to doubt things it was hitherto sure of, and which often remain instinctively certain to the mind despite its artificial doubts. Now we can also understand why philosophers so often have doubts which to the untrained look absurd, and why philosophers differ in their opinions on most important things, whereas mankind guided by its natural certitude is unanimous in them.
This certainty is destined to be the reliable guide of man through life. It precedes science, and can even exist without it. Long before there was a science of art and of jurisprudence the Babylonians and Egyptians had built their monuments, and Solon and Lycurgus had given their wise laws. And long before philosophers were disputing about the moral laws, men had the right view in regard to virtue and vice (cf. Cicero, De Oratore, I, 32). The same certitude is also destined to guide man in the more important questions, in the questions of religion and morality. The Creator of human nature and its destiny, who implanted instinct in the animal to guide it unconsciously in the necessities of life, has also given to man the necessary light to perceive with certainty truths without which it would be impossible to live a life worthy of man.
