A Pluralistic Universe · William James
ON THE NOTION OF REALITY AS CHANGING
In my _Principles of Psychology_ (vol. ii, p. 646) I gave the name of the 'axiom of skipped intermediaries and transferred relations' to a serial principle of which the foundation of logic, the _dictum de omni et nullo_ (or, as I expressed it, the rule that what is of a kind is of that kind's kind), is the most familiar instance. More than the more is more than the less, equals of equals are equal, sames of the same are the same, the cause of a cause is the cause of its effects, are other examples of this serial law. Altho it applies infallibly and without restriction throughout certain abstract series, where the 'sames,' 'causes,' etc., spoken of, are 'pure,' and have no properties save their sameness, causality, etc., it cannot be applied offhand to concrete objects with numerous properties and relations, for it is hard to trace a straight line of sameness, causation, or whatever it may be, through a series of such objects without swerving into some 'respect' where the relation, as pursued originally, no longer holds: the objects have so many 'aspects' that we are constantly deflected from our original direction, and find, we know not why, that we are following something different from what we started with.
Thus a cat is in a sense the same as a mouse-trap, and a mouse-trap the same as a bird-cage; but in no valuable or easily intelligible sense is a cat the same as a bird-cage. Commodore Perry was in a sense the cause of the new régime in Japan, and the new régime was the cause of the russian Douma; but it would hardly profit us to insist on holding to Perry as the cause of the Douma: the terms have grown too remote to have any real or practical relation to each other. In every series of real terms, not only do the terms themselves and their associates and environments change, but we change, and their _meaning_ for us changes, so that new kinds of sameness and types of causation continually come into view and appeal to our interest. Our earlier lines, having grown irrelevant, are then dropped. The old terms can no longer be substituted nor the relations 'transferred,' because of so many new dimensions into which experience has opened. Instead of a straight line, it now follows a zigzag; and to keep it straight, one must do violence to its spontaneous development.
Not that one might not possibly, by careful seeking (tho I doubt it), _find_ some line in nature along which terms literally the same, or causes causal in the same way, might be serially strung without limit, if one's interest lay in such finding. Within such lines our axioms might hold, causes might cause their effect's effects, etc.; but such lines themselves would, if found, only be partial members of a vast natural network, within the other lines of which you could not say, in any sense that a wise man or a sane man would ever think of, in any sense that would not be concretely _silly_, that the principle of skipt intermediaries still held good. In the _practical_ world, the world whose significances we follow, sames of the same are certainly not sames of one another; and things constantly cause other things without being held responsible for everything of which those other things are causes.
Professor Bergson, believing as he does in a heraclitean 'devenir réel,' ought, if I rightly understand him, positively to deny that in the actual world the logical axioms hold good without qualification. Not only, according to him, do terms change, so that after a certain time the very elements of things are no longer what they were, but relations also change, so as no longer to obtain in the same identical way between the new things that have succeeded upon the old ones. If this were really so, then however indefinitely sames might still be substituted for sames in the logical world of nothing but pure sameness, in the world of real operations every line of sameness actually started and followed up would eventually give out, and cease to be traceable any farther. Sames of the same, in such a world, will not always (or rather, in a strict sense will never) be the same as one another, for in such a world there _is_ no literal or ideal sameness among numerical differents. Nor in such a world will it be true that the cause of the cause is unreservedly the cause of the effect; for if we follow lines of real causation, instead of contenting ourselves with Hume's and Kant's eviscerated schematism, we find that remoter effects are seldom aimed at by causal intentions,[1] that no one kind of causal activity continues indefinitely, and that the principle of skipt intermediaries can be talked of only _in abstracto_.[2]
A friend of mine has an idea, which illustrates on such a magnified scale the impossibility of tracing the same line through reality, that I will mention it here. He thinks that nothing more is needed to make history 'scientific' than to get the content of any two epochs (say the end of the thirteenth and the end of the nineteenth century) accurately defined, then accurately to define the direction of the change that led from the one epoch into the other, and finally to prolong the line of that direction into the future. So prolonging the line, he thinks, we ought to be able to define the actual state of things at any future date we please. We all feel the essential unreality of such a conception of 'history' as this; but if such a synechistic pluralism as Peirce, Bergson, and I believe in, be what really exists, every phenomenon of development, even the simplest, would prove equally rebellious to our science should the latter pretend to give us literally accurate instead of approximate, or statistically generalized, pictures of the development of reality. I can give no further account of Mr. Peirce's ideas in this note, but I earnestly advise all students of Bergson to compare them with those of the french philosopher.
