We have seen in former Views that the whole Phenomenal Universe, as perceived by our senses, and all intellectual thoughts or concepts based on those perceptions, are, in reality, only mists or shadows; they have no existence apart from our physical senses, and may be likened to a thin film, which at death is pricked and passes away like a scroll, leaving us face to face with the Reality. We thus seemed to grasp that all phenomena, including our Physical Egos, are but the shadows or outline of the Reality, as depicted on our limited plane of consciousness; but these phenomena, having Motion for their basis, are none the less real to us under our present outlook, limited as it is by conditioning in Time and Space, and we have to deal with them as realities in our everyday life. I want to make this distinction clear in the present View.

Those of us who were youngsters in the ’sixties, and were fortunate enough to be taken to that land of wonders for children, the London Polytechnic, will remember seeing what were called Professor Pepper’s Ghosts. By means of a large sheet of glass on the stage, the reflection of a human being (otherwise invisible), which we will call the “unreal,” was, by the audience, seen walking alongside the people on the stage, and it was impossible to say which was the real and which the unreal. When the unreal was made to appear further back on the stage, it was apparently seen through the real figures and they appeared as ghosts, for they were seen to be transparent. If now we fix, perpendicularly on a table, a small pane of glass, and place, say, an orange in front and another orange behind it, we can arrange so that an observer, looking through the glass, sees two oranges alongside each other, one being the real and the other the unreal, and, with proper lighting and dark background, it is impossible to determine which is which, as they are both apparently real oranges. We will call the real, A, and the unreal, B; we now also introduce a human hand on both sides of the glass, and again we have apparently two real hands close to the oranges; if the real hand is now seen to try to touch the B orange, it passes through it, but it can take up the A; and the same result is seen when the unreal hand tries to grasp them, except that it can grasp the B but not the A; it is, in fact, only the unreal that can apprehend the unreal, and the real the real.

The above simile may help some of my readers to understand how the phenomena of Nature, though having no real existence apart from our senses, have the appearance of reality to us, because both we and the whole Phenomenal Universe are the unreal of our analogy, namely, the reflection or shadow of the Real on the physical plane. If we run against a stone wall, which is also part, with us, of the shadow, we hurt ourselves and acknowledge its existence, but to the Real it would not be an obstruction at all, it is not there. We know that this wall is not really solid, it is made up of Atoms revolving round each other but never touching, but the man in the street would give as the reason why it hurt, that it was dense, or what is called hard; if the wall were made of hay, or cotton wool, or of sunbeams, we should not suffer by running against it; in fact, the denser anything becomes, the more it shows its character of being real to our senses. If we take this as the true explanation for the Physical Universe, we are met with something quite beyond our powers of comprehension, when we try to form a conception of the all-pervading Ether; unless we may look upon it as actually a presentation of the Reality itself. If we wave our hand, we can feel the obstruction of the air, but we cannot feel the Ether. We think our earth very solid, and we know it is rushing round the sun at the enormous rate of 60,000 miles per hour, but it finds no obstruction in the Ether, there is no retardation of its velocity; and yet the study of Radio-Activity has quite lately shown us that that Ether is not only as dense as iron, or a hundred or a thousand times denser, but millions of times denser than that metal; and yet it permeates all matter like a sieve. In Sir Oliver Lodge’s words, “the Ether is so dense that matter by comparison is like a gossamer or a filmy imperceptible mist.” We can, therefore, by again using our “Ghost” analogy, understand why matter cannot obstruct the Ether, or vice versa; there is no perceivable friction between them, unless, as I shall presently suggest, we may find something akin to obstruction by Matter, not to Ether itself, but to its pressure, in the phenomenon of Gravitation.

The evidence we are gradually winning from Radio-Activity seems to be leading us to the conclusion that all forms of matter are but different motions or strains in the Ether (perhaps, as Lord Kelvin thought, in the form of vortices), that the different atoms of which matter is composed are, as suggested in View Three, apertures of different complexity of outline namely, those points at which Ether is absent or its density attenuated. Have we not apparently here another example of Positive and Negative, the Invisible the Ether, as the Real, and the Visible, the Material Universe, as its Negative the Unreal, similar to our list of Positives and Negatives in View One? Ether itself cannot be explained by any of the known dynamical laws, though it is probably the very root and cause of all of them; it is absolutely beyond our plane of perception or conception. We can only perceive certain effects of its presence when it comes into our limited world of consciousness, under the aspects of Time and Space namely, in its movements, which we classify as forms of matter and modes of energy.

It is only lately that we have been able to see clearly that the effects known to us as Light, Heat, Electricity, and Magnetism are caused by pulsations or rills of different rapidity in the Ether (this will be referred to in a later View); it is also probably the cause of what we call Gravitation, and we shall see that the action of Gravitation may, after all, be not in the direction of a pull but must be looked upon as a pushing force. Gravitation is common to all matter; in common language, every particle attracts every other particle with a force directly proportional to its mass, and inversely to the square of its distance; it is a very weak force compared with others we know, and difficult to measure except when a large mass of matter is involved. Perhaps this will be clearer, and not far from the truth, if I say that the force of Gravitation exerted between two masses of matter compared with that which we find acting between the constituents of matter namely, in chemical affinity, is comparable to the difference existing between the density of matter and the density of Ether.

The latest calculation of the pressure of the Ether is almost inconceivable namely, about 25,000 tons on the square inch, or 3,600,000 tons on the square foot; it may well therefore be that, in the degree of permeability of matter by the Ether, when we can calculate it, will be found the explanation of what we call Gravitation between two masses; they are each shielding the other from Ether pressure, in its own direction, with an obstructive force equal to its mass. The reason why the earth appears to attract us, is that it is shielding us from a certain amount of pressure in its direction; and we know that we are also apparently attracting every particle of the earth with a force proportionate to our mass, because we are, however slightly, shielding the earth from pressure in our direction; if this is the true explanation, Gravitation is a phenomenon of the Ether; it will be seen to be a movement of matter in the line of least pressure, and is therefore a push and not a pull.

Let us now come down to what we understand better concerning the subject of this View.

The question, “What is Truth?” “What is the Reality?” goes to the very root of the Riddle of the Universe. We are all trying in one direction or another to answer this question. As knowledge increases, old theories become untenable and have to be discarded, and, in their place, fresh ones are formulated to account for new phases of phenomena. There seems a general impression, among even thinking people, that scientists are wedded to, and always trying to find proofs for, their last theories, but this is not the case. The endeavour of the true seeker after truth is not so much to discover fresh facts which coincide with existing theories, as to find phenomena which cannot be explained thereby; there is indeed more joy over one fact which does not agree with preconceived theory, than over ninety-nine facts which are found to fall under that heading. In our everyday life we have become so accustomed to take for granted that what we see, hear, or feel by touch must be real, that it is difficult for the man in the street to realise that our senses woefully deceive us; that perception without knowledge often leads us astray into false concepts, and these false concepts lead us into difficulties which require fresh concepts to be formed, and these again demand further and more exact knowledge to be applied to perceived phenomena. This necessity for overcoming difficulties is the greatest incentive we have for gaining fresh knowledge of our surroundings. Owing to the fact, as already pointed out, that our sense perceptions are based upon the appreciation of change or motion, and must therefore be limited in Time and Space, and that the trueness of our conceptions of the Reality is dependent upon the knowledge which can be brought to bear upon those perceptions, we are forced to postulate two aspects of the Universe; one of these is what may be called the Visible, Finite, or Physical, which indeed carries the appearance of Reality to our limited senses, though it has no real existence for us apart from those senses, and the other is that which transcends our utmost conception, which we call the Invisible, the Infinite, or Spiritual.

At the outset of all investigation, we are forced to recognise that the only way we can approach conception of the Infinite is necessarily in the form of a negative, the negative applying to those things of which we have cognisance; we carry our thought to the utmost limit possible with our present knowledge, and, when we have come to a standstill, we conceive the Infinite to be not that but something further on. As our knowledge increases by small steps, that something further on seems ever to be flying from our grasp by mighty strides, until we are forced to bow our heads and recognise that we are in the presence of, though still not in sight of, the Reality. A divine impulse is ever urging us forward to greater conceptions but shattering our hopes, and giving us a feeling akin to despair, if we arrogate to ourselves a greater power of conception than we have knowledge to sustain; we have to approach the study with, indeed, that feeling of elation which the consciousness of our origin and destiny wakes within us, giving us a feeling of certainty that we are capable, in the hereafter, of attaining to the highest summit of knowledge, but with that humility, in the present, which makes us acknowledge that he who knows most knows most how little he knows. In this frame of mind let us now examine our surroundings.

We are living in a world of continuous and multitudinous changes; in fact, without change, we could have no cognisance of our surroundings, we should have no consciousness of living. We have become so accustomed to certain sensations that we are apt to take them, as facts, and scoff at the suggestion that they are non-realities. I propose, however, to show that what we perceive are not Realities, and true conception of our surroundings depends upon the knowledge which we can bring to bear to interpret the meaning of these sensations. It is only in response to our conscientious endeavours to form new concepts that knowledge is being daily revealed to us; the more we progress in Knowledge the more we see that Perception alone without Knowledge leads to false concepts, and these in their turn create fatal obstacles and difficulties to our progress towards the true appreciation of the Universe. Let me give a few examples.

In early times the Sun and the Stars were seen to revolve round the Earth once every day, and, without Knowledge of Astronomy, this was taken for granted as an absolute fact, and was looked upon as a reality; later on, however, it was noted that the Stars never changed their relative positions; this necessitated a new concept, namely, that they were fixed on the inner surface of a huge globe, which was also revolving. This false concept brought other difficulties into play, the question arose as to what was beyond the globe, and also the difficulty that, when the Stars as well as the Sun were found to be at such enormous distances from the Earth, their rates of motion were quite inconceivable. Even in the case of the Sun the motion represents over twenty-five million miles per hour, and the apparent motion of the Stars is thousands of times faster than Light travels. These insuperable difficulties were not swept away until, by the advance of Knowledge, the falsity of Conception, based only upon appearance, was made manifest, and it was seen that it was the Earth which revolved and not the Stars. Even then, owing to its supposed antagonism to what was stated in the Bible, the new Conception was opposed with great bitterness, it being long looked upon and denounced as a sacrilegious invention, and anybody daring to promulgate such a doctrine was threatened with death.

Our present Conception, that the Earth turns round on its axis once every day, and rolls in its orbit round the Sun once in every year, may be called a Reality to our finite Senses; but I shall show later on that, except for the finiteness of our senses and the imperfection of our Knowledge, the Concept is not a true one. With perfect Perception and perfect Knowledge we shall see that, apart from the two limitations or modes under which our physical senses act, there can be no such thing as Motion, because the very essence of Motion is but the product of those limitations, namely, Time and Space.

We are so accustomed to take everything for granted, that it may perhaps seem strange to question whether it can even be asserted that we have ever seen matter. Let us turn towards a common object in this room. We catch in our eyes the multitudinous impulses which are reflected from its surface under circumstances somewhat similar to those in which a cricketer “fields” a ball; he puts his hand in the way of the moving ball and catches it, and, knowing the distance of the batsman, he perhaps recognises, by the hard impact of the ball, that the batsman has strong muscles, but he cannot be said to see the batsman by that impact, nor can he gain thereby any idea as to his character. So it is with objective intuition; we direct our eyes towards an object, and catch thereby rays of light reflected from that object at different angles, and, by combining all these directions, we recognise form, and come to the conclusion that we are looking at, say, a chair. The eye also tells us that rays are coming in greater quantity from some parts of it, and we know that those parts are polished; the eye again catches rays giving higher or lower frequencies of vibration, and we call that colour; our eyes also tell us that it intercepts certain rays reflected from other objects in the room, and we know that it is not transparent to light; and those are our sight perceptions of a wooden chair.

We may go a little further by “pushing,” when we know, by the amount of resistance compared with the power exerted, what force of gravity is being exerted by and on that chair, and we declare it heavy or light, but by these means we get no nearer to the knowledge of what matter is. By tests and reagents we can resolve wood into other forms which we call Carbon, Oxygen, Hydrogen, Nitrogen, &c., which, because we cannot divide them into any other known substances, we call “Elements,” but we can only look at these in the same way as we are looking at the chair. Chemists, however, carry us a little further, and show us that the Elementary substances have not only their likes and dislikes, but their passionate desires and lukewarmness to others of their ilk, and, when opportunity offers, they break up with great violence any ordinary friendship existing between them and their neighbours, and seize on their coveted prey with a strength of will surpassing anything experienced in the Organic World; and this new association they maintain, until they, in their turn, are dispossessed, or they encounter another substance of still greater attraction, when they leave their first love and take up new connections.

I shall touch upon the subject of what matter is later on; meanwhile let us consider how, owing to our senses being limited by the considerations of Time and Space, we are surrounded by inconceivables, and yet it is those very inadequate conceptions which force us to acquire Knowledge; the greatest incentive we have to pursue our investigation is, as we have seen, the fact that Perception without sufficient Knowledge leads us into difficulties. Let me give you two instances of these inconceivables. Infinite Space is inconceivable by us, but it is also quite as inconceivable, or perhaps even more so, to think of Space being limited, and yet we are forced to declare that one of these two must be true. Again, Matter is either composed of ultimate bodies, of a certain size which cannot be divided, or is infinitely divisible; both of these are inconceivable, the latter for the same reason as that of the Infinity of Space, and the former because it is inconceivable that the ultimate body could not be divided into two parts by a sharp edge forced between its two sides, or by a stronger force than at present holds it together; it has indeed been suggested as an explanation that, if an atom could be divided, it might cease to be matter, that its parts would have no existence, but it is difficult to conceive how two nothings can form one something.

Another example of Perception leading to a false Concept is our Sense of Pain; we apply a red-hot coal to the tip of one of our fingers and our Perception would have us believe that we feel intense pain at the point of contact, but we know this to be a false Concept, as it can be shown that the pain is only felt at the brain: there are in communication with different parts of our body small microscopical nerve threads, any of which may be severed with a pen-knife close to the base of the skull, with the result that no pain can then be felt, although the fingertip is just as much alive and is seen to be burning away.

Another example is our Sense of Hearing. A musical sound is made up of a certain number of pushes in a second, but each push is silent. It is only, as we have seen, a musical sound to our Sense when the pushes recur at intervals of not more than the sixteenth part of a second. The prongs of a tuning-fork, vibrating 500 times per second, seem to be travelling very quickly, but are really only moving at the rate of 10 inches per second, or not much over half a mile per hour, when the amplitude is the hundredth part of an inch, which gives quite a loud sound.

Light is also composed of rills in the Ether, but the rill itself is not Light, it is only Light when these rills strike, with a certain enormous frequency, on a special organ adapted for, we might say, counting these frequencies, and if these frequencies fall below that certain number, or above twice that number per second, there is no Sense of Sight.

How few people have ever realised what a wonderful Counting Machine they possess in their organ of Sight! I think the best method I can adopt, to bring this clearly before you, is to take our tuning-fork, vibrating 500 times per second, a rapidity which to some will be even difficult to comprehend, and then ask you to consider how long that fork must continue to vibrate before it has accomplished the full number of frequencies, which must necessarily impinge upon the eye in one second of time, before the phenomenon of sight becomes possible. That tuning-fork would have not only to continue its vibrations without diminution for seconds, minutes, hours, weeks, months, years, or hundreds of years, but for 30,000 years before it has accomplished the full number of pulsations which, as Ether waves, must strike the eye in one second of time, to give the impression of Light; the calculation is easy, the rills of Red Light are so small that 40,000 of these only cover one inch of length, and light travels 186,000 miles per second. If therefore the number of inches in 186,000 miles are multiplied by the 40,000, and the product is divided by the 500 times which the tuning-fork vibrates in one second, you have the number of seconds that tuning-fork must vibrate, before it has completed the number of impacts which, in one second of time, must fall on our retina to give us the impression of red light; and that tuning-fork would have to vibrate nearly twice as long, say 50,000 years, to reach the number of impulses which strike the eye in one second of time and give the impression of violet light; and between these two limits are situated the colours Orange, Yellow, Green, Blue, and Indigo.

What a marvellous sense then is Sight, when we find that, not only can it grasp these innumerable vibrations, but can actually differentiate colours, appreciating as a different colour each increase of about one-tenth in these multitudinous frequencies; and it is principally by means of this Sense of Sight that we gain a knowledge of what is happening around us. And yet what strides we have made in the last two hundred years to improve upon that instrument! With all its wonderful capabilities, we shall see later on that the eye is a very imperfect instrument for seeing very small objects, or even large objects when at a great distance. With the present compound Microscope, only developed in the last hundred years, and its apochromatic lenses, invented only in the last forty years, we are able to see and photograph objects of a minuteness immeasurably beyond the power of the human eye, and, with our telescopes, we can see and photograph stars far beyond the possibility of vision by the unaided eye; and yet, by the stellar spectroscope, we are actually able to examine and identify the very atoms of which that distant star is composed, or rather was composed hundreds of thousands of years ago; we can compare those atoms with the same atoms in our laboratories, and we find that, though the former are hundreds of thousands of years older than the latter, they show absolutely no signs of wear or loss of energy, though they have been for that enormous time, and are still, pulsating at the rate of not only millions but billions of times per second; and though the pulsations they emit have travelled across such a vast depth of space that the mind cannot even imagine the distance, there has not been any diminution in the numbers of pulsations per second, nor the slightest slowing down of the rate of flight at which they started on their journey from that far-off world. If there had been the slightest change we could detect it at once by means of the Spectroscope.

With another instrument we are able, not only to hear but to converse audibly, as long as we like, with another human being a thousand miles away, who is also sitting comfortably in his own arm-chair and speaking to us with as much freedom as though we were both in the same room. With another instrument we can go further, and exchange thoughts, in a few seconds, with a being on the other side of the world, by means of a thin wire that is itself fixed, and does not move, and we have lately invented another means by which we can do the same, over several thousands of miles, without even a connecting wire. With another instrument we have gone far beyond the facility with which the Printing press enabled us to communicate our thoughts to our fellow human beings, we can actually imprint our very words and laughter upon a wax cylinder and send it to the antipodes, and our friends there, with a similar instrument, can not only hear and recognise our very voice, but can make that voice repeat our thoughts audibly, to a thousand others at the same time, and can repeat that process for hundreds of times without exhausting that voice. With another instrument we can depict on a film, not only the images of our friends but their very actions, which may also be sent to any distance, and the persons, thereon depicted, may be seen by their relatives alive and going about their everyday employments, with every movement exact to life. We can cross the Ocean against the wind and waves by means of harnessed sunbeams, without any exertion of our own, at the rate of an express train, which train, by the by, is also moved by the same means; we can dive to the bottom of the sea and journey there for hours, in perfect safety, without coming to the surface, and we are even developing wings, or their equivalent, which from immemorial tradition we were not to possess before we had finished doing our duty properly in this world and had gained admission to the next.

We can do all these things, but how ignorant we still are in the commonest doings of Nature! By giving up our whole lifetime, and spending millions of pounds, we could never make a grain of wheat or an acorn, and wherever we turn we find ourselves confronted with mysteries beyond our power to explain from a finite material standpoint; even in material vibrations we meet a mystery almost beyond our power to comprehend. Take for instance those small insects, of the family of Grasshoppers, which make the primaeval woods of Central America give out a noise like the roaring of the sea, a wondrous sound never to be forgotten by those who have heard it. By means of a kind of rasp one of these insects creates a sound which Darwin states can be heard to the distance of one mile: these insects weigh less than the hundredth part of an ounce, and the instrument by which the noise is made, weighs much less than one-tenth of the total insect; it is less therefore than one thousandth part of an ounce in weight, and yet it is found, by calculation, that this small instrument is actually able to move at the enormous rate of a thousand vibrations per second and keep in motion for hours, from five to ten million tons of matter, and it does this so powerfully that every particle of that enormous bulk of matter gives out a sound audible to our ears. But even these millions of tons are not its limit of action, for we know that these vibrations must go on until, in the end, every particle of matter connected with this earth has been affected by each of those vibrations.

All our difficulties of understanding the true meaning of these and other phenomena around us are, as I have already pointed out, caused by our inability to recognise that vibration or motion has no reality, it is a pseudo-conception arising from the fact that our senses are entirely dependent upon the two modes or limitations, Time and Space, for their very action, and that, as conceptional knowledge is based upon perceptional knowledge, our very consciousness of living is also dependent upon these same limitations. We have seen that Motion is nothing but the product of these two modes of perceptions, and, in my next Views, I shall examine these elusive limitations, these two mysteries of Time and Space, the forever and the never-ending; I shall trace them to the utmost limit of our conception, and try to gain thereby a clearer insight into the fact, not only that the whole Physical Universe is but a transient and Space-limited phenomenon, a thin film which our senses have erected and which divides us from the Reality, but that, if our power of introspection were fully developed, we should know that the Reality is nearer and dearer to us, and has much more to do with us, even in this life, than has the physical.
