Man or Matter Part 30

And more clearly still in the following part of his poem An Infant Eye: 'A simple Light from all Contagion free, A Beam that's purely Spiritual, an Ey That's altogether Virgin, Things doth see Ev'n like unto the Deity; That is, it s.h.i.+neth in an hevenly Sense, And round about (Unmov'd) its Light dispense.

'The visiv Rays are Beams of Light indeed, Refined, subtil, piercing, quick and pure; And as they do the sprightly winds exceed, Are worthy longer to endure; They far out-shoot the Reach of Grosser Air, With which such Excellence may not compare.

But being once debas'd, they soon becom Less activ than they were before.'

How at this stage the soul experiences the act of perception in itself is shown in the following pa.s.sage from the poem Wonder:

'A Nativ Health and Innocence Within my Bones did grow And while my G.o.d did all his Glories show I felt a vigour in my Sense That was all SPIRIT: I within did flow With seas of Life like Wine.'

Utterances of this kind ill.u.s.trate the fact that perception of the ur-images of the world consists in a reading with the eye-of-the-spirit, which has been rendered so strong that for its action no support from the physical eye is any longer required. This faculty of spiritual Imagination (which Rudolf Steiner was able to exercise in advance of other human beings) is acquired on a path of training which is the direct continuation of the Goethean path.1

It remains to show that acceptance of information obtained through spiritual Imagination, without ourselves being as yet in actual command of it, is not in contradiction with the principles of 'reading'. Let us, to this end, think of reading in the ordinary sense of this word, calling to mind that for the acquisition of this faculty we depend on someone who can teach it because he already has it. Exactly the same holds good for the reading with which we are here concerned. Here, too, a teacher already possessing this faculty is required. Thus Goethe became for us a teacher of reading, and it would be a mistake to imagine that he, for his part, needed no teacher. In his case this function was fulfilled partly by what he learned through his studies of the earlier fruits of man's spiritual activity, that is, from an epoch when vestiges at least of the original, instinctive faculty of spiritual Imagination were still extant. A similar function on our own path of study was performed by our occupation with the old doctrine of the four elements and the basic concepts of alchemy.

Indispensable as is such a training in reading by turning to past conceptions of man, it does not suffice to meet the present-day demands of a scientific understanding of the universe. For this, we need a 'technique' of reading that cannot be attained along these lines alone.

Awareness of this fact led Rudolf Steiner to pursue his spiritual-scientific investigations and to communicate the results in such a way that they can be a 'school of reading' for those who study them.2 In point of fact we have already made use in this sense of one of the results of Rudolf Steiner's researches, for at the very beginning of this book his picture of the threefold psycho-physical organism of man was taken as the basis of our own investigations. The reason why the present remarks were not then included is that the relevant results of higher research were in that case of such a nature that, once known, they could be confirmed by the simplest kind of self-observation. The fact, however, remains that from the very beginning we have called upon one fully trained in reading, to help in deciphering certain facts of nature - in this case of human nature.

A similar need, though now in an amplified form, arises at the present stage of our studies. And here, out of the wealth of knowledge conveyed by Rudolf Steiner from the realm of supersensible Imagination, it is his characterization of the four modifications of levity which will now give the guidance necessary for our own observation. Adopting the terminology chosen by him for the description of this sphere, we shall in future speak of it as of the 'Ether' pervading the universe (thus using this word also in its true and original meaning). Accordingly, we shall refer to its fourfold differentiation as to the four kinds of ether: Warmth-Ether, Light-Ether, Chemical Ether and Life-Ether.

(b) WARMTH

We begin with the warmth-ether as the only modification of ether which combines certain etheric with certain physical properties. Const.i.tuting as it does a border-condition between the two worlds, the warmth-ether has, on the one hand, the function of receiving the picture-weaving transmitted to it by the higher ethers, and, on the other, of bringing physical matter into the state where it becomes receptive to the working of the etheric forces. The warmth-ether achieves this by freeing matter from being controlled one-sidedly by the centre-bound forces of the earth. It thus calls forth, when acting physically, the processes of melting of solids and of evaporation of liquids: phenomena which yielded the initial observations for our introduction of the concept of levity. In processes of this kind we now recognize the physical manifestation of a universal function of the warmth-ether, namely, to divest matter of all form and to lead it over from the realm dominated by gravity into that of levity. Provided we attach the right meaning to the word, we may say that the function of the warmth-ether is to bring about chaos at the upper border of physical nature. It is thus that we have already found it working in the plant, when through the union of the pollen with the seed a state of chaos is produced within the seed, which enables the type to impress anew its form-principle into it.

Another instance of the warmth-ether's anti-gravitational effect, also discussed earlier, is the earth's seismic activity. True, it appears at first sight as if little were gained by speaking of warmth-ether, instead, as we did previously, of levity in general. But it must not be forgotten that in the ether-realm as a whole, warmth - that is, the overcoming of earthly gravity - is only one of the four modes of etheric action, albeit the one which enables the other three to work into the physical world. We shall see, later on, that only by taking into account the action of the higher modifications of the ether is it possible to gain insight into the true causes of the apparently so arbitrary occurrences of volcanic and kindred phenomena. Here, too, it is the function of the warmth-ether to produce in the physical sphere the chaos which is necessary to make the physical sphere receptive to the activities going on in higher spheres.

In view of this universal function of the warmth-ether, which distinguishes it from the other modifications of ether, we may give it as a second name that of 'chaoticizing ether'.

(c) LIGHT

The function of the light-ether, the second of the four modes of ether, can best be envisaged by thinking of the difference between a plant growing in darkness (perhaps a potato sprouting in a cellar) and another of the same species exposed to the influence of the light. On Plates VII and VIII two kinds of unicellular organisms are shown, of one which - the green algae - is accustomed to live in light, the other - the bacilli - in darkness. These things are, of course, well-known facts. Our purpose here, however, is not merely to record them as 'fact', but, by re-creating them within ourselves, to use them to gain an experience of the function of the light-ether.

The following pa.s.sages from Goethe's Metamorphosis of Plants are a cla.s.sical example of observation of the activity of the light-ether in the plant. They are taken from the second part of the essay, where Goethe is describing leaf-development:

'While the leaves owe their first nourishment princ.i.p.ally to the more or less modified watery parts, which they draw from the stem, they are indebted for their increased perfection and refinement to the light and air. The cotyledons which are formed beneath the closed seed-sheath are charged, so to speak, with only a crude sap; they are scarcely and but rudely organized and quite undeveloped. In the same way the leaves are more rudely organized in plants which grow under water than in others which are exposed to the open air. Indeed, even the same species of plant develops smoother and less intricately formed leaves when growing in low damp places, whereas, if transplanted to a higher region, it will produce leaves which are rough, hairy and more delicately finished.'

'So it is also with the anastomosis of the vessels which spring forth from the larger veins, seeking each other with their ends and coalescing, and thus providing the necessary basis for the leaf-skin or cuticle. All this, if not entirely caused by subtle forms of air, is at least very much furthered by them. If the leaves of many water-plants are thread-like or a.s.sume the form of antlers, we are inclined to attribute it to lack of complete anastomosis. The growth of the water b.u.t.tercup, Ranunculus aquatilis, shows this quite obviously, with its aquatic leaves consisting of mere thread-like veins, while in the leaves developed above water the anastomosis is complete and a connected plane is formed. Occasionally, indeed, in this plant, the transition may be still more definitely observed, in leaves which are half anastomosed and half thread-like.'

The second of these paragraphs describes the phenomenon of vascular anastomosis which, having already been more than once an object of our study, here reveals a new meaning. If, following Goethe's method, we re-create in our mind the repeated separations and reunions of the sap-vessels, while keeping in view the fact that the leaf's outer form is the result of a purposive, many times repeated anastomosis, then the picture of the activity of weaving arises before our mind's eye. (Hence the word 'tissue' for the flesh of a living being.) In truth all nature's forms are woven of light, including the crystals.3

How clear a picture Goethe had of the conformity of man's act of thinking with nature's way of producing her forms - both being an act of supersensible weaving - is shown by the following two verses. That on the left is a pa.s.sage from Faust, from the scene in which Mephisto (disguised as Faust) instructs the young Scholar. The other is an altered version of it, written by Goethe at a later time to conclude an essay (Bedenken und Ergebung) in which he deals with the problem of the relation between Experience and Idea:

Truly, when men their thoughts conceive 'Tis as if some masterpiece they weave.

One thread, and a thousand strands take flight, Swift to and fro the shuttles going, All unseen the threads a-flowing, One stroke, and a thousand close unite.1

So with a modest eye perceive Her masterpiece Dame Nature weave.

One thread, and a thousand strands take flight, Swift to and fro the shuttles going, Each to the other the threads a-flowing, One stroke, and a thousand close unite.4 -

What Goethe wants to show here by applying to the activity of nature the same image which he used originally to depict the act of thinking, we can express to-day by saying that it is the ident.i.ty of the activity of the light-ether in human thinking and in external nature which is responsible for the fact that the objective ideas operating in nature can become the content of man's consciousness in the form of thoughts.5

Following our previous procedure when we gave the warmth-ether a second name by calling it chaoticizing ether, we can denote the light-ether also as 'weaving ether'.

If at this point in our discussion we revert once more to the realm of physical manifestations of light, dealt with in the preceding chapters, we do so because by studying them in the present context we shall gain further insight into the fact that one plane of nature provides ill.u.s.trations of processes which on another plane remain more or less veiled. At the same time this will help us to learn more about the properties of levity-s.p.a.ce. The optical phenomenon which we shall discuss in this sense is that of the so-called pin-hole camera. (The pin-hole camera effect is easily produced by a keyhole in a closed door which on one side faces a window and on the other leads to a comparatively dark room.)

The usual explanation of the appearance of the optical image on the back inside wall of such a camera is that light-rays, emanating from every point outside, cross each other in the aperture of the camera and so - again point by point - create the inverted image. No such explanation, clearly, is open to us. For the world of external objects is a whole, and so is its image appearing in the camera. Equally, the light entering the camera is not a sum of single rays. Pure observation leads to the following description of the optical process.

By surveying the path which the light takes from the illuminated surface of the outer objects via the pin-hole to the optical image inside the camera, we realize that the light-realm engaged in this process has the shape of a double cone, with its apex in the opening of the camera. Within this cone the light carries the image across the s.p.a.ce stretching in front of the light-reflecting objects up to the point where the image becomes visible by being caught on the back wall of the camera.

Thus in every section of the cone the image is present in its totality - even in the very apex of the cone. There, too, the image in all its details is present as a whole, though without (ideally) any spatial extension. Seen thus, on this level of its action the light-ether reveals as one of its characteristics the faculty of making present in a s.p.a.celess point an image originally expanded in s.p.a.ce, and of letting it emerge from this point in spatial expansion.

Further, there is the fact that, wherever we set up a pin-hole camera, the aperture in its front will cause the formation of an optical image inside it. This shows that each point in s.p.a.ce filled with light is the bearer of an optical image, contracted to a point, of the entire world of light-reflecting objects surrounding it. All we do with such a camera is to select a particular image and bring it to separate visibility.

Through these observations we grow aware of light's faculty of communicating simultaneously to s.p.a.ce as a whole, and to each point in it, a potential image of the light-reflecting object.

What we observe here in the sphere of physical light-activity is exactly what the light-ether performs on a higher level of nature when with its help the spiritual archetype of a plant takes on spatial appearance. For to this end the archetype, itself without spatial limitations, imprints its image into the tiny seed, whence the growing plant organism carries it again into s.p.a.ce. And there is in principle no limitation to the number of such seeds, each of which will bear the complete image of the archetype.

(d) SOUND

The characteristics of the third modification of ether are such that they prompted Rudolf Steiner to give it as a second name, besides chemical ether, that of sound-ether. In view of the fact, stressed at the beginning of this chapter, that perception of the ether is achieved by a heightening of the power of the spirit-eye, it must cause surprise to learn that a certain mode of activity of the ether has a quality which makes appeal to aural experiences. The full answer to this riddle must await the discussion that follows this chapter. Two points, however, may be brought forward at once. Firstly, where gravity, with its tendency to individualize, is absent, no such sharp distinctions exist between one form of perception and another as are found in the sphere of the physical senses.6 Secondly, even in ordinary sense-perception a certain overlapping of visual and aural experiences is known to us. We need only think how common it is to give musical attributes, such as 'consonant' and 'dissonant' to colours, and to describe tones as 'light' and 'dark'. The reason is that subconsciously we accompany visual experiences with tone-sensations, and vice versa.

Cases are even known of human beings in whom the secondary sensation occurs with such intensity as to equal the primary one. Such people say that they 'see' sounds and 'hear' colours.

Everything that is true of the supersensible sphere we may expect to come to expression in some form in the world of sense-perception. The sphere of the ether is the sphere of the creative archetypes of the world, and when we learn that to one part of this world the character of sound is attributed, we must search for a phenomenon, perceptible to our senses, which reveals to us the secret of the sound's form-creating power. This we have in the so-called sound-figures, discovered by the German physicist Chladni (1756-1827) and called after him 'Chladni's sound-figures'. A short description of how they are produced will not be out of place.

A round or square plate of gla.s.s or bra.s.s, fixed at its centre so that it can vibrate freely at its edges, is required. It is evenly and not too thickly covered with fine sand or lycopodium powder and then caused to vibrate acoustically by the repeated drawing of a violin-bow with some pressure across the edge of the plate until a steady note becomes audible. Through the vibrations thus caused within the plate, the particles of sand or powder are set in movement and caused to collect in certain stationary parts of the plate, thereby creating figures of very regular and often surprising form. By stroking the plate at different points on the edge, and at the same time damping the vibrations by touching the edge at other points with the finger, notes of different pitch can be produced, and for each of these notes a characteristic figure will appear (Fig. 14).7

The significance for us of Chladni's experiment will emerge still more clearly if we modify it in the following way. Instead of directly setting the plate with the powder into vibration by stroking it with the bow, we produce a corresponding movement on a second plate and let it be transmitted to the other by resonance. For this purpose the two plates must be acoustically tuned to each other and placed not too far apart. Let us imagine, further, that the whole experiment was arranged - as it well might be - in such a way that the second plate was hidden from a spectator, who also lacked the faculty of hearing. This gives us a picture of the situation in which we find ourselves whenever the higher kinds of ether by way of a tone-activity inaudible to our physical ear, cause shapeless matter to a.s.sume regularly ordered form.

This comparison of the activity of the sound-ether, as the form-creating element in nature, with Chladni's phenomenon is drawn correctly only if we recognize that the conception of form, as an expression of that which is called forth through the etheric forces in nature, comprises more than the external spatially bounded shape of an organic or inorganic ent.i.ty. Apart from the fact already indicated, that for the formation of such ent.i.ties the co-operation also of life-ether is necessary, we can judge the activity of sound-ether correctly only if we conceive it as a much more inward activity, compared with the formation in external s.p.a.ce of Chladni's figures. In the latter case, the reason why the influence of sound causes nothing beyond the ordering of form in outer s.p.a.ce is because on this plane of nature the only changes that can occur are changes in the positions of separate physical bodies. Where the forces of sound in ether-form are able to take hold of matter from within, they can produce changes of form of a quite different kind. This effect of the activity of sound-ether has given it its other name: chemical ether.

We have mentioned once before that our conception of 'form' in organically active nature must not be limited merely to that of a body's spatial outline. This was in connexion with Ruskin's definition of the spiritual principle active in plant-formation as 'the power that catches out of chaos charcoal, water, lime and what not, and fastens them down into a given form'. Besides the external order of matter revealed in s.p.a.ce-form, there exists also an inner qualitative order expressed in a body's chemical composition. Upon this inner chemical order is based all that we encounter as colour, smell, taste, etc., of a substance, as well as its nouris.h.i.+ng, healing or harmful properties.

Accordingly, all these parts of an organism, both in the plant-kingdom and within the higher organisms, have a certain inner material order, apart from their characteristic s.p.a.ce-structure. The one is never present without the other, and in some way they are causally connected.

In this inner order of substance we must see in the very first place the work of the sound or chemical ether. And we should be aware that by the word 'chemistry' in this connexion we mean something much more far-reaching than those chemical reactions which we can bring about by the reciprocal affinity of physical substances, however complicated these reactions may be. A few examples will ill.u.s.trate the difference between chemical processes caused by direct influence of the chemical ether, and others in which only the physical consequences of the ether are effective.

In his book, Man the Unknown, Professor Carrel shows very impressively, by an example from the human organism, the difference of quant.i.tative ratio in externally similar processes, one of which occurs within the domain of life, the other, outside it. He compares the quant.i.ty of liquid necessary to keep artificially alive a piece of living tissue which has been reduced to pulp, with the quant.i.ty of blood doing the same within the living organism. If all the tissues of a human body were treated in this way, it would take 45,000 gallons of circulating fluid to keep them from being poisoned in a few days by their own waste products. Within the living organism the blood achieves the same task with 1J gallons.

Very many chemical changes within living organisms are effected by the two polar processes of oxidation and reduction. We have discussed them repeatedly as hieroglyphs of much that occurs in nature by way of polarity. In accordance with the principle ruling the physical plane of nature, that differences of level tend to disappear, oxidation can occur by itself, whereas reduction requires the expenditure of energy.

Let us from this point of view compare the transformation of oxidized into reduced iron, as it takes place inside and outside the realm of life.

An example of this process in its purely physical form is the reduction of iron-ore to metallic iron in blast-furnaces, where, with the help of high temperature and high pressure, carbon is made to combine with the oxygen ingredient of the ore and to impart to it its own imponderable energy. Precisely the same process is going on continuously and un.o.btrusively within the human body under normal bodily conditions of temperature and pressure, when the oxy-haemoglobin of the arterial blood changes over into the haemoglobin of the venous blood. A macrotelluric counterpart of this is the transformation of the red river-mud into the blue-black continental mud at the bottom of the sea, around the continental sh.o.r.es. Here, again, reduction takes place without those preliminaries that are necessary for carrying through the process by technical means.
