A priori, however, it is not self-evident that the sole business of our mind with realities should be to copy them. Let my reader suppose himself to constitute for a time all the reality there is in the universe, and then to receive the announcement that another being is to be created who shall know him truly. How will he represent the knowing in advance? What will he hope it to be? I doubt extremely whether it could ever occur to him to fancy it as a mere copying. Of what use to him would an imperfect second edition of himself in the new comer's interior be? It would seem pure waste of a propitious opportunity. The demand would more probably be for something absolutely new. The reader would conceive the knowing humanistically, 'the new comer,' he would say, 'must TAKE ACCOUNT OF MY PRESENCE BY REACTING ON IT IN SUCH A WAY THAT GOOD WOULD ACCRUE TO US BOTH. If copying be requisite to that end, let there be copying; otherwise not.' The essence in any case would not be the copying, but the enrichment of the previous world.
I read the other day, in a book of Professor Eucken's, a phrase, 'Die erhohung des vorgefundenen daseins,' which seems to be pertinent here. Why may not thought's mission be to increase and elevate, rather than simply to imitate and reduplicate, existence? No one who has read Lotze can fail to remember his striking comment on the ordinary view of the secondary qualities of matter, which brands them as 'illusory' because they copy nothing in the thing. The notion of a world complete in itself, to which thought comes as a passive mirror, adding nothing to fact, Lotze says is irrational. Rather is thought itself a most momentous part of fact, and the whole mission of the pre-existing and insufficient world of matter may simply be to provoke thought to produce its far more precious supplement.
'Knowing,' in short, may, for aught we can see beforehand to the contrary, be ONLY ONE WAY OF GETTING INTO FRUITFUL RELATIONS WITH REALITY whether copying be one of the relations or not.
It is easy to see from what special type of knowing the copy-theory arose. In our dealings with natural phenomena the great point is to be able to foretell. Foretelling, according to such a writer as Spencer, is the whole meaning of intelligence. When Spencer's 'law of intelligence' says that inner and outer relations must 'correspond,' it means that the distribution of terms in our inner time-scheme and space-scheme must be an exact copy of the distribution in real time and space of the real terms. In strict theory the mental terms themselves need not answer to the real terms in the sense of severally copying them, symbolic mental terms being enough, if only the real dates and places be copied. But in our ordinary life the mental terms are images and the real ones are sensations, and the images so often copy the sensations, that we easily take copying of terms as well as of relations to be the natural significance of knowing. Meanwhile much, even of this common descriptive truth, is couched in verbal symbols. If our symbols FIT the world, in the sense of determining our expectations rightly, they may even be the better for not copying its terms.
It seems obvious that the pragmatic account of all this routine of phenomenal knowledge is accurate. Truth here is a relation, not of our ideas to non-human realities, but of conceptual parts of our experience to sensational parts. Those thoughts are true which guide us to BENEFICIAL INTERACTION with sensible particulars as they occur, whether they copy these in advance or not.
From the frequency of copying in the knowledge of phenomenal fact, copying has been supposed to be the essence of truth in matters rational also. Geometry and logic, it has been supposed, must copy archetypal thoughts in the Creator. But in these abstract spheres there is no need of assuming archetypes. The mind is free to carve so many figures out of space, to make so many numerical collections, to frame so many classes and series, and it can analyze and compare so endlessly, that the very superabundance of the resulting ideas makes us doubt the 'objective' pre-existence of their models. It would be plainly wrong to suppose a God whose thought consecrated rectangular but not polar co-ordinates, or Jevons's notation but not Boole's. Yet if, on the other hand, we assume God to have thought in advance of every POSSIBLE flight of human fancy in these directions, his mind becomes too much like a Hindoo idol with three heads, eight arms and six breasts, too much made up of superfoetation and redundancy for us to wish to copy it, and the whole notion of copying tends to evaporate from these sciences. Their objects can be better interpreted as being created step by step by men, as fast as they successively conceive them.
If now it be asked how, if triangles, squares, square roots, genera, and the like, are but improvised human 'artefacts,' their properties and relations can be so promptly known to be 'eternal,' the humanistic answer is easy. If triangles and genera are of our own production we can keep them invariant. We can make them 'timeless' by expressly decreeing that on THE THINGS WE MEAN time shall exert no altering effect, that they are intentionally and it may be fictitiously abstracted from every corrupting real associate and condition. But relations between invariant objects will themselves be invariant. Such relations cannot be happenings, for by hypothesis nothing shall happen to the objects. I have tried to show in the last chapter of my Principles of Psychology [Footnote: Vol. ii, pp. 641 ff.] that they can only be relations of comparison. No one so far seems to have noticed my suggestion, and I am too ignorant of the development of mathematics to feel very confident of my own view. But if it were correct it would solve the difficulty perfectly. Relations of comparison are matters of direct inspection. As soon as mental objects are mentally compared, they are perceived to be either like or unlike. But once the same, always the same, once different, always different, under these timeless conditions. Which is as much as to say that truths concerning these man-made objects are necessary and eternal. We can change our conclusions only by changing our data first.
The whole fabric of the a priori sciences can thus be treated as a man-made product. As Locke long ago pointed out, these sciences have no immediate connection with fact. Only IF a fact can be humanized by being identified with any of these ideal objects, is what was true of the objects now true also of the facts. The truth itself meanwhile was originally a copy of nothing; it was only a relation directly perceived to obtain between two artificial mental things. [Footnote: Mental things which are realities of course within the mental world.]
We may now glance at some special types of knowing, so as to see better whether the humanistic account fits. On the mathematical and logical types we need not enlarge further, nor need we return at much length to the case of our descriptive knowledge of the course of nature. So far as this involves anticipation, tho that MAY mean copying, it need, as we saw, mean little more than 'getting ready' in advance. But with many distant and future objects, our practical relations are to the last degree potential and remote. In no sense can we now get ready for the arrest of the earth's revolution by the tidal brake, for instance; and with the past, tho we suppose ourselves to know it truly, we have no practical relations at all. It is obvious that, altho interests strictly practical have been the original starting-point of our search for true phenomenal descriptions, yet an intrinsic interest in the bare describing function has grown up. We wish accounts that shall be true, whether they bring collateral profit or not. The primitive function has developed its demand for mere exercise. This theoretic curiosity seems to be the characteristically human differentia, and humanism recognizes its enormous scope. A true idea now means not only one that prepares us for an actual perception. It means also one that might prepare us for a merely possible perception, or one that, if spoken, would suggest possible perceptions to others, or suggest actual perceptions which the speaker cannot share. The ensemble of perceptions thus thought of as either actual or possible form a system which it is obviously advantageous to us to get into a stable and consistent shape; and here it is that the common-sense notion of permanent beings finds triumphant use. Beings acting outside of the thinker explain, not only his actual perceptions, past and future, but his possible perceptions and those of every one else. Accordingly they gratify our theoretic need in a supremely beautiful way. We pass from our immediate actual through them into the foreign and the potential, and back again into the future actual, accounting for innumerable particulars by a single cause. As in those circular panoramas, where a real foreground of dirt, grass, bushes, rocks and a broken-down cannon is enveloped by a canvas picture of sky and earth and of a raging battle, continuing the foreground so cunningly that the spectator can detect no joint; so these conceptual objects, added to our present perceptual reality, fuse with it into the whole universe of our belief. In spite of all berkeleyan criticism, we do not doubt that they are really there. Tho our discovery of any one of them may only date from now, we unhesitatingly say that it not only IS, but WAS there, if, by so saying, the past appears connected more consistently with what we feel the present to be. This is historic truth. Moses wrote the Pentateuch, we think, because if he didn't, all our religious habits will have to be undone. Julius Caesar was real, or we can never listen to history again. Trilobites were once alive, or all our thought about the strata is at sea. Radium, discovered only yesterday, must always have existed, or its analogy with other natural elements, which are permanent, fails. In all this, it is but one portion of our beliefs reacting on another so as to yield the most satisfactory total state of mind. That state of mind, we say, sees truth, and the content of its deliverances we believe.
Of course, if you take the satisfactoriness concretely, as something felt by you now, and if, by truth, you mean truth taken abstractly and verified in the long run, you cannot make them equate, for it is notorious that the temporarily satisfactory is often false. Yet at each and every concrete moment, truth for each man is what that man 'troweth' at that moment with the maximum of satisfaction to himself; and similarly, abstract truth, truth verified by the long run, and abstract satisfactoriness, long-run satisfactoriness, coincide. If, in short, we compare concrete with concrete and abstract with abstract, the true and the satisfactory do mean the same thing. I suspect that a certain muddling of matters hereabouts is what makes the general philosophic public so impervious to humanism's claims.
