TIME
In the last View I referred to the mysteries of Time and Space as twin-sisters; they have, as we saw, many aspects in common, and are the two modes or conditions under which all our senses act and by which our thoughts are limited. We arbitrarily divide each of these two mysteries into two parts, which parts are separated from each other, in either case, by a point which has, apparently, as its centre, our very consciousness of living. In the case of Space we call this point the Here, and on one side of it, as we saw in our last View, we have extension towards the infinitely great, and, on the other, intension towards the infinitely small. In the case of Time we call the middle point the Now, and on one side of this we place the duration of Time towards the future, and, on the other, we place what we call the duration of Time towards the past. In the case of Space we have the here and the overthere, equivalent in Time to the present and the future, but, though Time and Space are, as it were, twin-sisters, upon whose combined action depends our very consciousness of living, we do not treat them both equally.
It is a remarkable fact that the human race on this particular world has, in some inexplicable way, come to look upon the future as non-existent until we arrive at, and are able to perceive, with our senses, what is happening there; this is all the more inexplicable when we realise that in traversing Space we certainly have to move to get anywhere, but in traversing Time we have nothing equivalent to movement. This curious way of looking upon the future as non-existent, may be another sign that our race is still in its infancy, but is more probably caused by human beings having always hitherto looked upon Time not only as a reality but as actually moving or extending along a line from past to future eternity; whereas, under our present outlook, we have no consciousness of the existence of Time except by intervals between successive thoughts; our consciousness of the very existence of Time is based upon our Physical Ego repeating the present, by saying to itself the words, Now—Now—Now; but there is nothing that can be called movement in this, any more than if you are standing still and saying, Here—Here—Here—relating to Space. Time is, as it were, "marking time," and as the present in time is common to all space, Time is "marking time" everywhere, and the Now therefore includes the whole of the past and the whole of future eternity everywhere. We shall get a clearer understanding of this later on; meanwhile, we are face to face with the fact that we look upon the future as non-existent.
This curious state of things is probably only accidental to the present stage of development of the human mind, and may, at any time, be rectified by perhaps either a slight rearrangement of that slender network of nerves upon which depends our faculty of thinking, or the joining together of a few microscopical filaments attached to the cells in the grey cortical layer, or even a single bridge thrown across from one convolution to another of the brain; a very slight alteration would open up to our consciousness the present existence of the future. The prime perceivable difference between our brains and those of the Apes and lower animals is the larger number of enfoldments, or convolutions, that are developed by the Human. Each new line of thought, or sequence of thoughts, requires, and is provided with, a new wrinkle or small convolution, and it probably only requires the attention of the human race to be fixed, for a time, on the consideration of this subject, to evolve the slight alteration, or bridge, necessary to enable us to see that the future, as also the past, does actually exist and is included in the Now. It may make this a little clearer to consider that if you maintain that, in traversing the duration of time, the future does not exist until you arrive there, you should also in fairness insist that, in travelling through the extension of Space, your destination, say Rome, does not exist until you get there and can see it with your senses.
As we have, in the former six Views, been gradually mounting above the mists and illusions of our everyday thoughts, and can look through our Window with, I hope, a clearer vision, I shall venture in this present View to carry the subject of the Future still further, and show that, just as we have now before us and can read the papyri which were written 5000 years ago, so it is possible to conceive that books, written and being written and printed 5000 years hence, are at present in existence, and that it is even possible the human race has actually already read them; whether we shall be able to see them and read them in our own lifetime may be open to question; that may again depend upon the development of special cross-circuiting of brain filaments. Meanwhile, in order to carry our present View to the utmost limit of our conception, in a manner somewhat similar to what we did for Space, I will again ask you to join me in a thought-flight towards the appreciation of this second great Mystery.
With this object in view we will first consider the human senses of sight and hearing, commencing with sound, or the vibrations which affect the tympanum of the human ear. Sound travels in air at about 1130 feet per second, and if the vibrating body, giving out the sound, oscillates sixteen times in one second, it follows that, spreading over this 1130 feet, there will be sixteen waves, giving a length of about 70 feet to each wave. This is the lowest sound that the human ear can appreciate as a musical note, and is, what may be called, the fourth Octave above one vibration in one second. When the number of vibrations in a second sinks below sixteen, the ear no longer appreciates them as a musical sound, but is able to hear them as separate vibrations or beats. The easiest way of illustrating this is by means of a revolving disc, with sixteen holes pierced at regular intervals round the edge, and a jet of high-pressure air, which is forced through each of the holes successively as they revolve. When the disc does not quite complete one revolution in a second, only fifteen puffs come to the ear in a second of time, and they are heard as puffs; but when the rate reaches one revolution in a second, the sound, as if by magic, changes into the lowest musical sound. The same result may be obtained in a more pronounced form by means of explosions or pistol shots; when these are slow and heard separately, they are painful and almost unbearable to the ear, but, as soon as their rapidity, namely, at sixteen per second, gets beyond the power of the ear to differentiate between the explosions, the impression, as if by magic, changes into a continuous or musical sound, like a thirty-foot pipe note of an organ.
To go back to our disc. The octave above this lowest musical note is obtained by doubling the rate of puffs, namely, by revolving the disc twice in one second, and the next octave by revolving four times in a second, and so on, doubling each time, until, at about the thirteenth octave, the sound has become so high that the majority of listeners cannot hear it, and fancy it must have stopped, whereas a few will still be saying: "How shrill it is!" At last, at about the fourteenth octave, when there are 20,000 beats to the second and each wave is about half an inch long, it passes beyond human audition, and, although we can show that the air is still vibrating, all is silent, the human ear being incapable of hearing so many beats in a second even as a continuous sound, though I have evidence to show that many insects can hear probably considerably beyond this limit. It is, however, possible to make these higher vibrations perceptible to our senses by means of what are called sensitive flames: we can actually, by these, measure the length of these silent waves, and as we know the rate at which they travel, we can at once compute the number which occur in a second of time, and thus ascertain their pitch. By this means we can follow for about three more octaves above the audible limit, namely, up to 160,000 pulsations per second, with a length of wave of one-twelfth of an inch.
Two and a half octaves above these numerically, i.e. at about the twentieth octave, we reach the frequency of Electro-Magnetic Rills, used by the Marconi System of wireless telegraphy, which pulsate at about 950,000 per second, and have a wave-length of something like 1000 feet. The reason for this great increase in length of wave is caused by these frequencies being propagated in the Ether at the rate of 186,000 miles per second, instead of, as with sound waves, in the air, at only 1130 feet per second. We can trace these particular frequencies, called, after their discoverer, Hertzian waves, for about fifteen octaves, when we arrive at the frequency of 32,000,000,000 in a second, with a wave-length decreased to a quarter of an inch; we can render the effect of these waves visible, but have no physical organ by which we can feel these pulsations. After this, however, we get into the region of frequencies which, though still of exactly the same kind, we know and can feel as Radiant heat; these are situated in the next fourteen octaves, and bring us up to those subtle frequencies which affect another of our sense organs, and which we appreciate as light; these we have already seen have the enormous frequency of 530,000,000,000,000 pulsations per second for red light, up to 930,000,000,000,000 per second for violet, and having wave-lengths so small that it takes 40,000 and 70,000 of them respectively to cover one inch in length. There is only a little over half an octave that the eye can appreciate as light, and then all is darkness; but we can still go on further by the help of Science: beyond the violet we have the actinic or chemical rays, which are used in photography, and which enable us to trace the frequencies for a further two octaves. Beyond this we cannot pierce with our present knowledge; but there may be, and probably are, latent in our nature, senses which, properly developed, will be able to appreciate still more subtle vibrations, and organs which, perhaps, even now are being prepared for the reception of these influences.
We have no organs yet developed for receiving and appreciating what are called Wireless waves, but we have already been able to devise physical Receivers, of wonderful sensitiveness, for them and other waves of the same nature, such as those of Radiant heat. In the case of Radiant heat, the Bolometer invented by Professor Langley has been able to receive and record a change of temperature of the one millionth of a degree Centigrade, and can easily make visible the heat of a candle at a distance of one and a half miles. In wireless telegraphy also the Receiver, perfected by Marconi, is affected by rills, made by a splash of electric discharge, over 3000 miles away. If our eyes were sensitive to these frequencies, both of which are composed, as is also light, of electro-magnetic rills, we could see anything that was happening anywhere in the world, for they go through matter as though it did not exist, as light passes through glass; indeed, if our region of Sight waves was only put an octave lower we could not use glass in our windows, it would be too opaque, we should be obliged to have our windows made of thin slabs of carbon or other substances permeable to Radiant heat waves. Science indeed steadily points to electricity and magnetism being a form of motion, and it may be that in these invisible rays we may some day discover the nature of those mysterious forces; and, even far beyond those, as suggested in View Four, we may in the not far distant future be able to appreciate Physical Life itself as a mode of frequency.
We want, as it were, a special "Time Microscope," which I have already referred to, to examine these vibrations, and a method similar to that already mentioned in "Space," under Celestial Photography, by which we may traverse and examine hundreds or thousands of octaves by each second of exposure; for, although the path extends to infinity, we have already arrived at the utmost limits of our finite senses, and find that after all we can only appreciate fifty-one octaves, a few inches only, as it were, along the line of Infinite extent, reaching from the finite up to the Reality; and even so it must be borne in mind that we have only travelled in one direction, whereas the path we have taken extends in the opposite direction also to infinity. We started with sixteen vibrations in a second, as the lowest number of beats we human beings can appreciate as a musical sound; let us now descend by octaves. The octave below is eight vibrations in a second, and there are probably many animals that can only hear these as a musical sound; the next octave is four, then two, and then one vibration in a second. But we do not stop there; the octave below this is one vibration in two seconds, then in four seconds, eight seconds, sixteen seconds, and so on, until it is possible to conceive that even one frequency in a million years might be appreciated as a musical sound, or even as one of the colours of the spectrum, by a being whose time sensations were enormously extended in both directions, but still finite.
Once more we must call a halt. Our finite minds become bewildered in attempting even to glance at these infinities of time.
We measure space by miles, yards, feet, and inches; we measure time by years, hours, minutes, and seconds; and by these finite units we try to fathom these two marvellous infinities. With our greatest efforts of thought we find, however, that we can get relatively no distance whatever from the Here of Space and the Now of Time. It is true that the present, as a mathematical point, appears to be hurrying and bearing us with it along the line stretching from the past to future eternity, but in reality we get no further from the one nor nearer to the other. Let us change our view and examine this subject under a different aspect.
First of all, look round a room and note the different objects to be seen. Even in a small room we do not see the objects as they really are at this instant, but only as they were at a certain fixed length of time ago. The present time is common to every point in space and each person is in the present, but only to his own perception; to everyone else in the room, each individual is, at this moment, being seen acting in the past; those objects which are further away are being seen further behind in point of time than those that are nearer; in fact, however near we are to an object, we can never see it as it is but only as it was. We are dealing with very minute differences here, they being based upon the rate at which light travels; but they are differences which are known with a wonderful degree of accuracy.
We have here another example of how perception without knowledge leads to false concepts. When anyone views an extended landscape, he thinks that his sight shows him that the same point of Time, which he is experiencing, is common to every man, animal, plant, or material visible there, but we know now that he is seeing every part of that scene in the past compared with himself. Just as all objects therein are situated at separate distinct points of space, so to our vision the objects of that scene are acting or existing in different epochs of time. An Artist gives us on a flat surface a picture of that landscape, and his representations of all objects in that scene appear therefore to us as being in the same moment of Time, but to get that effect he has to draw objects at a distance smaller than those close at hand; a fly in the foreground has to be drawn larger than a horse supposed to be in the distance, though both are on the same flat surface; they have the same parallax and are therefore the same distance from the observer, and as this produces a similar image on our retina, we accept it though we know it is only a make-believe; it serves its purpose by giving us an impression on our retina which we have learnt to interpret as representing that landscape, but such a picture would indeed be a marvel of absurdity to a being who had perfect sight, such as we have already referred to, and who could appreciate parallel rays; in such a vision there would be no perspective, no vanishing point in perception.
Now let us take a wider landscape. The Moon is 240,000 miles distant. We do not, therefore, ever see her as she is but as she was 1-1/4 seconds ago. In the same way we see the Sun as he was eight minutes ago, and we see Jupiter as he was nearly an hour ago. Let us look still further to one of the nearest fixed stars. We at this moment only see that star as it was more than ten years ago; that star may therefore have exploded or disappeared ten long years ago, and yet we still see it shining, and shall continue to see it there until the long line of light has run itself out; all around us, in fact, we see the appearance of blazing suns not as they are now but as they were thousands of years ago, and, by the aid of the telescope and of our sensitive plate, we are only now recording the light which started from clusters and firmaments probably millions of years ago.
Now let us take the converse of this. To anybody on the moon at this moment the earth would be seen from there not as it is, but as it was 1-1/4 seconds ago, and from the sun as it was eight minutes ago, and if we were in Jupiter, and were looking back, we should, at this particular moment, be viewing what was happening on this earth, and seeing what each of us was doing an hour ago. Now let us go in imagination to one of the nearest fixed stars, and looking back we should see what was happening ten years ago; going still further to a far-off cluster, the light would only just now be arriving there, which started from the earth at the time when man first appeared; or we might go to so remote a distance that the scene of the formation of the Solar System would be only now arriving there, and all the events which have taken place from that remote time to the present would, as time rolled on, reach there in exactly the same succession as they have happened on this earth; and remember that we should be looking, from that great distance, at all these past events with the same intuitional advantage as though we were actually present here in time, for however near we are to an object, we never see it as it is but only as it was in the past.
Let us but turn to any point of space and we shall find at each point, according to its remoteness, the actual scenes of the past being enacted, in fact it may be said that throughout infinite space every event in past eternity is now indelibly recorded.
A murder committed hundreds of years ago, in a country house, may never have been found out, the criminal and his victim have alike turned to dust, the blood has been washed from the floor, the very house and its surroundings have crumbled and disappeared, and in their place a waving corn field is all that can be seen, but at this very moment if we were at a certain point in space, we should now be witnessing there, the whole actual living scene from beginning to end, as though we were present here hundreds of years ago: the murderer standing over his victim, the knife driven in and the blood gushing out. If we went further away we should at this same moment be seeing the criminal just arriving and knocking at the door of that house, then going upstairs into the room, and the same terrible scene with all its minutiæ would again be enacted. From a point still further removed, we should now see him, say, having lunch at a country inn some miles away, concocting his villainy, then he would be seen walking across the fields towards the house, again knocking at the door, mounting the staircase, and once more would that murderous scene be enacted before our eyes, and so on for ever; the scene, with the house and its surroundings, have indeed been completely swept away from the present here, but the whole tragedy will always be acting in the future there in the presence of the Reality.
Let us now come, in imagination, towards the earth, from some far-off cluster of stars. If we traverse the distance in one year, the whole of the events from the formation of this world would appear before us, only thousands of times quicker. Make the journey in a month, a day, an hour, a second, or a moment of time, and all past events, from the grandest to the most trivial, would be acted in an infinitesimal portion of time.
When we have fully grasped this we recognise that Omniscience is synonymous with Omnipresence, and some may find, in this thought, a glimpse of that Great Book wherein are said to be registered every thought, word, and deed, which, in the direction of the Reality, has helped to nourish, or, in the direction of the shadow, has tended to starve the personality of each one of us; for we know that every word we utter, or that has been uttered from the beginning of the world, and every motion of our brain connected with thought is indelibly imprinted upon every atom of matter. If our sense of perception were greatly increased we need not go to Palestine to see on the rocks there the impressions of the image of Christ and His disciples, or of the words they uttered as they passed by, but any stone by the wayside here would show His every action and resound with every word He uttered. In fact, every particle of matter on this earth is a witness to that which has happened, every point in space and every moment of time contains the history of the past in the smallest minutiæ. The Here, embracing all space, and the Now, embracing all time, are the only realities to the Omniscient.
Let us once more change the scene and we may grasp even more clearly that Time and Space are not realities but are only modes or conditions under which our material senses act. A tune may be played either a thousand times slower or a thousand times quicker, but it still remains the same tune, it contains the same sequence of notes and proportion in time, the only characteristics by which we recognise a tune. And so in the same way with our sense of sight, an event may be drawn out to a thousand times its length or acted a thousand times quicker, it is still the same scene. An insect vibrates its wings several thousands of times in a second and must be cognisant of each beat, whereas we have seen that we, with our Senses of Sight and Hearing, can only appreciate respectively at the most seven and sixteen vibrations in a second as separate beats. That insect must therefore be able to follow a flash of lightning under the conditions of a Time microscope magnifying a thousand times compared with our vision. The whole life of some of these insects extends over a few hours only, but owing to their quick unit of perception it is to them as full of detail as our life of seventy years; but to them there is no day and night, the Sun is always stationary in the Heavens, they can have no cognisance of Seasons.
I have already referred in View One to the curious results of increasing our unit of perception by a Time Microscope, and I will now carry the investigation of this subject a step further.
As conceptional knowledge is based on perceptional knowledge, and we can only perceive about six times per second, and as the principal forms of knowledge are gained through the eye, we are conceiving progress in phenomena under a very restricted outlook; we cannot recognise such slow motions as, for instance, the hour-hand of a watch, the growth of a tree, or rise of the tide, except by noting the change that has occurred after a long interval; there is therefore a whole world of events which we cannot see. Owing to this limit, in our unit of time perception, we also cannot perceive events which are taking place beyond a certain quickness, they become blurred and give the impression of continuity, and constitute another world of events lost to us. For the same reason there is a whole world of sensation lost to us by our limited unit of sound perception; we cannot follow separate sound-events if they occur quicker than sixteen in a second, beyond that they become blurred and give the impression of continuity. If, on the other hand, our units of perception were increased a thousandfold, as is probably the case with some insects, our conscious lives would contain a thousand more events than they do at present, and, as the consciousness of length of life is dependent upon the number of events that have been perceived, we should under these conditions have passed on this earth a life equivalent to, say, 70,000 years under our present restricted unit; every second of that long period would have been as full of events for us as is a second in our present life of seventy years. If, on the other hand, our unit of perception were decreased a thousandfold, our length of life, based upon perception of events, would be no longer than 25-1/2 of our present days; if our life were actually reduced to that period (so as to regain our present units of perception) we should be old and grey-headed before the sun had risen for the twenty-fifth time since our birth. If our unit of perception, with our length of life, were again reduced a thousandfold, the whole of our life of seventy years would now only be equal to forty-three minutes, and, in the whole of that life, we could only see the sun move ten degrees, namely, twenty of its own diameters in the heaven; if we were born, say, at noon on midsummer's day, we could never have any idea of anything but daytime, and neither our fathers, nor grandfathers, nor great-grandfathers for fifteen generations before them could have seen the sun rise; but there would have been a tradition, handed down from a far distant past generation, that a long time ago, beyond the memory of man, there was no sun at all, everything was pitch dark, and that time was called the "Great Shadow." If their records could have gone still further back for the same length of time they would have heard that, before the "Great Shadow," the sun was always shining in the heavens, and that that great "Sun" day lasted twice as long as the great shadow.
To understand more clearly this subject of Time perception let me put another aspect before you; we are looking, say, at an insect whose wings are beating several thousand times per second, and, with our vision limited to six times per second, it would be impossible to count the number of hairs on that wing, or to see which of those hairs were split, or were bent from the straight, but, if we travelled away from that insect into space at the rate of light, and were looking back, the present would then always be with us; the wing, although still vibrating at that enormous rate, would appear to be stationary, and so would every other moving thing on the earth, however quick its movement, and everything would continue in that motionless state for a million years, provided we continued our flight with the rays of light. If we travelled a little slower than light, say one minute less in a thousand years, the same scene would be presented to us, but, that which was acted upon this earth during one minute of Time, would now take a thousand years to accomplish; the swiftest railway train would appear standing still, it would take 5-3/4 days and nights to cover each inch of ground. It is thus possible to again understand how the flight of a bird or the lightning flash might be examined under conditions of time which would lead to the discovery and tracing of even the principle of life itself. But let us go one step further and increase our flight beyond the rate at which light travels: scenes would now progress in the opposite direction to that which we are accustomed to; men would get out of bed and dress themselves at night and go to bed in the morning; old men would grow young again; tall trees would grow backwards and enter the earth, embedding themselves in the seed, and the seed would rise upwards to the branch that nourished it; the blood would turn into chyle, into food in the stomach, into the piece of meat, which would be transferred from the mouth to the plate, and would then be cut on to the joint, the joint would go down to the kitchen and be uncooked, would be carried to the butcher to be cut on to the carcase, and the animal would come to life and go out into the fields. Human bodies would be formed in the ground from the dust of the Earth, passing through what we call corruption to incorruption, the dead would be taken from their graves, brought back to their homes and put to bed; the Doctor would arrive, a miracle would happen, the patient would come to life; though this would hardly be a feather in the cap of the Doctor, as it would be seen that the medicine came out from the mouth of the patient, would be put into bottles to be thrown away, and it would be the Doctor who had to pay the Fee, and the bigger the Doctor the bigger the Fee he would have to pay. The future would in fact change places with the past, the effect would give birth to the cause as presented to our finite senses, and, though it is difficult to realise, it is indeed just as true, or untrue, that we come into this world through the grave, instead of in the way we are accustomed to, because to the Reality there is no change, the Here and the Now comprising all beginnings and ends, all causes and effects.
In this flight on the wings of light we did not in reality depart in the least from the Here, because there is no such thing as space, it is all included in a mathematical point, the Here; and as the whole of time is included in the Now, the Future, however remote with all events therein, is existent in the present; the writers of books 5000 years hence are therefore writing them now, and the Human Race has read and is reading them now; we have always hitherto maintained that these things are only "going to happen" 5000 years hence, but in reality all events in the future are events in the same Now in which we are living at the present moment, and, as it is just as true, that time is flowing from the Future to the Present and on to the Past, as in the contrary direction (of our present outlook), so it is quite conceivable that we may some day, in the not far distant future, not only realise that the future exists already, but that we may even be able to handle and read the books written 5000 years hence, in a similar manner to that which enables us now to handle and read those which were written 5000 years ago.
