The Life of Reason: The Phases of Human Progress. George Santayana

of the sounds. If this is true of so abstract and mathematical a perception as is counting, how emphatically true must it be of continuous and infinitely varied perceptions flowing in from the whole spatial world. Glimpses of the environment follow one another in quick succession, like a regiment of soldiers in uniform; only now and then does the stream take a new turn, catch a new ray of sunlight, or arrest our attention at some break.

      The senses in their natural play revert constantly to familiar objects, gaining impressions which differ but slightly from one another. These slight differences are submerged in apperception, so that sensation comes to be not so much an addition of new items to consciousness as a reburnishing there of some imbedded device. Its character and relations are only slightly modified at each fresh rejuvenation. To catch the passing phenomenon in all its novelty and idiosyncrasy is a work of artifice and curiosity. Such an exercise does violence to intellectual instinct and involves an æsthetic power of diving bodily into the stream of sensation, having thrown overboard all rational ballast and escaped at once the inertia and the momentum of practical life. Normally every datum of sense is at once devoured by a hungry intellect and digested for the sake of its vital juices. The result is that what ordinarily remains in memory is no representative of particular moments or shocks—though sensation, as in dreams, may be incidentally recreated from within—but rather a logical possession, a sense of acquaintance with a certain field of reality, in a word, a consciousness of knowledge.

      Can the transcendent be known?

      But what, we may ask, is this reality, which we boast to know? May not the sceptic justly contend that nothing is so unknown and indeed unknowable as this pretended object of knowledge? The sensations which reason treats so cavalierly were at least something actual while they lasted and made good their momentary claim to our interest; but what is this new ideal figment, unseizable yet ever present, invisible but indispensable, unknowable yet alone interesting or important? Strange that the only possible object or theme of our knowledge should be something we cannot know.

      Can the immediate be meant?

      An answer these doubts will perhaps appear if we ask ourselves what sort of contact with reality would satisfy us, and in what terms we expect or desire to possess the subject-matter of our thoughts. Is it simply corroboration that we look for? Is it a verification of truth in sense? It would be unreasonable, in that case, after all the evidence we demand has been gathered, to complain that the ideal term thus concurrently suggested, the super-sensible substance, reality, or independent object, does not itself descend into the arena of immediate sensuous presentation. Knowledge is not eating, and we cannot expect to devour and possess what we mean. Knowledge is recognition of something absent; it is a salutation, not an embrace. It is an advance on sensation precisely because it is representative. The terms or goals of thought have for their function to subtend long tracts of sensuous experience, to be ideal links between fact and fact, invisible wires behind the scenes, threads along which inference may run in making phenomena intelligible and controllable. An idea that should become an image would cease to be ideal; a principle that is to remain a principle can never become a fact. A God that you could see with the eyes of the body, a heaven you might climb into by a ladder planted at Bethel, would be parts of this created and interpretable world, not terms in its interpretation nor objects in a spiritual sphere. Now external objects are thought to be principles and sources of experience; they are accordingly conceived realities on an ideal plane. We may look for all the evidence we choose before we declare our inference to be warranted; but we must not ask for something more than evidence, nor expect to know realities without inferring them anew. They are revealed only to understanding. We cannot cease to think and still continue to know.

      Is thought a bridge from sensation to sensation?

      It may be said, however, that principles and external objects are interesting only because they symbolise further sensations, that thought is an expedient of finite minds, and that representation is a ghostly process which we crave to materialise into bodily possession. We may grow sick of inferring truth and long rather to become reality. Intelligence is after all no compulsory possession; and while some of us would gladly have more of it, others find that they already have too much. The tension of thought distresses them and to represent what they cannot and would not be is not a natural function of their spirit. To such minds experience that should merely corroborate ideas would prolong dissatisfaction. The ideas must be realised; they must pass into immediacy. If reality (a word employed generally in a eulogistic sense) is to mean this desired immediacy, no ideal of thought can be real. All intelligible objects and the whole universe of mental discourse would then be an unreal and conventional structure, impinging ultimately on sense from which it would derive its sole validity.

      There would be no need of quarrelling with such a philosophy, were not its use of words rather misleading. Call experience in its existential and immediate aspect, if you will, the sole reality; that will not prevent reality from having an ideal dimension. The intellectual world will continue to give beauty, meaning, and scope to those bubbles of consciousness on which it is painted. Reality would not be, in that case, what thought aspires to reach. Consciousness is the least ideal of things when reason is taken out of it. Reality would then need thought to give it all those human values of which, in its substance, it would have been wholly deprived; and the ideal would still be what lent music to throbs and significance to being.

      Mens naturaliter platonica.

      The equivocation favoured by such language at once begins to appear. Is not thought with all its products a part of experience? Must not sense, if it be the only reality, be sentient sometimes of the ideal? What the site is to a city that is immediate experience to the universe of discourse. The latter is all held materially within the limits defined by the former; but if immediate experience be the seat of the moral world, the moral world is the only interesting possession of immediate experience. When a waste is built on, however, it is a violent paradox to call it still a waste; and an immediate experience that represents the rest of sentience, with all manner of ideal harmonies read into the whole in the act of representing it, is an immediate experience raised to its highest power: it is the Life of Reason. In vain, then, will a philosophy of intellectual abstention limit so Platonic a term as reality to the immediate aspect of existence, when it is the ideal aspect that endows existence with character and value, together with representative scope and a certain lien upon eternity.

      More legitimate, therefore, would be the assertion that knowledge reaches reality when it touches its ideal goal. Reality is known when, as in mathematics, a stable and unequivocal object is developed by thinking. The locus or material embodiment of such a reality is no longer in view; these questions seem to the logician irrelevant. If necessary ideas find no illustration in sense, he deems the fact an argument against the importance and validity of sensation, not in the least a disproof of his ideal knowledge. If no site be found on earth for the Platonic city, its constitution is none the less recorded and enshrined in heaven; nor is that the only true ideal that has not where to lay its head. What in the sensualistic or mystical system was called reality will now be termed appearance, and what there figured as an imaginary construction borne by the conscious moment will now appear to be a prototype for all existence and an eternal standard for its estimation.

      It is this rationalistic or Platonic system (little as most men may suspect the fact) that finds a first expression in ordinary perception. When you distinguish your sensations from their cause and laugh at the idealist (as this kind of sceptic is called) who says that chairs and tables exist only in your mind, you are treating a figment of reason as a deeper and truer thing than the moments of life whose blind experience that reason has come to illumine. What you call the evidence of sense is pure confidence in reason. You will not be so idiotic as to make no inferences from your sensations; you will not pin your faith so unimaginatively on momentary appearance as to deny that the world exists when you stop thinking about it. You feel that your intellect has wider scope and has discovered many a thing that goes on behind the scenes, many a secret that would escape a stupid and gaping observation. It is the fool that looks to look and stops at the barely visible: you not only look but see; for you understand.

      Identity and independence predicated of things.
