Knowledge and Immortality

GA 69b — 19 February 1910, Düsseldorf

I. Knowledge and Immortality

Dear attendees! When a person, after a day's work and toils, takes a little time to reflect and tries to find his way in the life of the soul, the question arises as to how the individual facts of life, how the individual experiences are connected with the whole human destiny, with the great goal of human life in general. One of the questions that then arises for the soul is undoubtedly that of the meaning of human knowledge.

When we talk about knowledge, we can initially mean that knowledge which relates to the direct services of practical life, to everything that enables us to get to know the outside world in such a way that we can put it at the service of our practical interests. The question becomes somewhat different when we consider knowledge that attempts to penetrate the deeper foundations of life, the riddles of existence – knowledge that does not lead us to an immediately practical work and activity. It is said that man has an immediate urge to know and that knowledge is valuable in itself. Those who look deeper will hardly be satisfied with such an answer. What value would knowledge have if it were only an inner image, only a repetition of what is outside in the world? Why should that which is weaving in the world be effective in the outer world and be repeated in one's own soul only as in a mirror? Is it really only the satisfaction of a soul urge that pushes for knowledge that reaches beyond the everyday? This question will occupy us today: the goal and destiny, essence and significance of human knowledge.

If we mean the concept of knowledge that many people have today, which consists in saying that knowledge should provide us with a true reflection of what the world is experiencing, then it will not be easy to relate knowledge to the great goals and tasks of human existence. We will have to ask ourselves: Is knowledge really only the repetition of something external? Or is it one of the forces that must work in our soul in order to advance it on the paths it must traverse in its existence in the world?

This question cannot be answered by external science; it can only be answered if we consider the whole human being. External science only provides us with information about what our senses perceive and our minds grasp. But beyond this ordinary science, there is something that is trying to become part of our entire spiritual life today, which can be called spiritual science or anthroposophy.

What does theosophical spiritual science seek to comprehend? It seeks to comprehend the whole human being. Let us first agree on what that means, the whole human being. When we look at a person, we see two strictly separate states within the normal human existence of today. These two states, which life presents to us, are so familiar to the human being that he does not even notice that the greatest riddles of existence are hidden in them. We express these states in the words “waking and sleeping”. We recall that from time immemorial many philosophies have called sleep the little brother of death. We can combine these words with two others, namely with the words “life and death”. In these words we have a large part of what we can count among the riddles of existence.

Let us try, starting from what presents itself to us in the most ordinary way, to understand the changing states of waking and sleeping. In the waking state, we try to comprehend all the impressions that constantly flow into our soul - impressions that our senses transmit to us, everything that fills us with joy, desire and pain, in short, what constitutes what we call our mental life. We see this ebb and flow of drives, desires, passions, and so on, plunging into an indeterminate darkness in the evening. During sleep, it transitions into another state, that of unconsciousness. It would be absurd to say that the human being as a being of soul disappears in the evening and is reborn anew in the morning. We must ask ourselves: where is that which works in us throughout the day, where is it when we let our soul life sink into an indeterminate darkness in the evening? We are immediately pointed to answers that cannot be given from an ordinary, sensory perspective, because that perspective escapes precisely that which hides behind the nocturnal state in the evening. The question of where the soul is at night can only be answered by theosophical spiritual science, because it rises from the knowledge of the sensual to the knowledge of the supersensible, from the visible to the invisible.

We need to come to an understanding about how theosophical spiritual science can arrive at such supersensible insights by once again taking a brief look at what really fulfills our entire life during the day. We can say that we live with our soul during the day through external stimulation, through external impressions. In the evening, the external stimuli fade away, creating the emptiness of the sleeping state. But because a person in the normal life of today's existence can lead a soul life only when external perceptions evoke from his soul that which we are currently experiencing, we can imagine that the inner work of the soul dies, withers away when the external stimuli are not there. Must it be so?

That it need not be so can be seen if one accepts the experiences of clairvoyant consciousness. What knowledge of the sensory world is comes about through the stimulus of the sensory world. Supersensible knowledge can only come about through the soul's willingness to unfold work within itself, in order to develop powers and abilities even when there are no stimuli from the external sensory world. The possibility of developing such inner powers is given to us by the method of spiritual schooling. This method is there for those who want to penetrate into the knowledge of the supersensible world. This method can only be briefly hinted at here. Those who want to get to know it thoroughly can find it in the book “How to Know Higher Worlds”. We shall only briefly indicate here how man can find within himself the abilities to ascend to knowledge of the higher worlds.

The first thing is that man learns to artificially evoke, through a strong willpower, what otherwise only comes in the state of unconsciousness, namely, what man experiences when the sensory impressions cease. He must be able to command all outer impressions to stop; all outer impressions around him must fall silent, just as they do in the evening when we fall asleep. But this moment must take place through his will, in full consciousness. He would be like a sleeper if he could awaken nothing in his own soul. But although all outer impressions fall silent, he learns to unfold strong powers; he draws out of the deep recesses of his soul what slumbers there. No outer efforts are needed; they are intimate soul processes. There is a sinking into strong, vigorous thoughts, which are not given from without, but which the soul forms for itself.

This is meditation or concentration, as it is called – a drawing together of thoughts. Without external impressions we must feel joy and sorrow. The spiritual researcher lets powerful, strong thoughts arise in his own soul, thoughts that have nothing to do with the external world, and these are ideals as well as impulses of the will. These must have a stronger effect than external impressions; the soul must be seized by them intensely and powerfully. If a third element were not added, these perceptions would have the effect of volcanoes. This is that through a strong effort of will an inner calm and quiet can be brought about despite these impulses. Then the spiritual researcher experiences - even if only after a long time - the great moment that can be compared to the moment when a blind person suddenly regains his sight after an operation. Just as the impressions of the external world flood into the soul of the blind man after an operation, so too does everything that was previously unavailable to him.

This fact makes it clear to us that there can only be a supersensible world for us if the organ of perception for it is present. When this organ is awakened, a new world opens up. We must not decide about what we do not know, but only about what we know. These organs, which are necessary for recognizing the supersensible world, are developed through meditation or concentration in the calm of our soul. Then “spiritual eyes” and “spiritual ears” arise - to use an expression of Goethe. It could now be objected: Yes, it may be that the spiritual researcher experiences a higher world, but what do the spiritual worlds have to do with the others who cannot ascend to them? — That is not correct. The spiritual eye is necessary for recognition [of the supersensible worlds], but to understand what the spiritual researcher has to say, unbiased reason is sufficient, and therefore it concerns all people.

Someone in whom the higher organs are awakened can observe such a phenomenon as sleep. It is a very different state from that of waking. Only part of the human being remains in the physical world during sleep, the other part, the soul-spiritual, withdraws from the physical body when falling asleep and returns to its home, the spiritual world. The spiritual world need not be imagined as a different place; it is all around us. We have human nature, divided into two parts; during waking these are together, but during sleeping they are separated. But human nature is not yet fully explained. We can get a rough idea of the two parts that go out at night by comparing man with the animals that are closest to him of all visible creatures. We also find instincts, desires, and feelings in animals. Even if they are not present in the same perfection, they are still more or less present in animals, and only those who cannot rise to a higher [contemplation] will consider them to be the same as in humans. We need only think of something that is usually not emphasized in external science; we need only remember that, for example, in the German language there is a word that cannot be called to anyone from the outside, [the word “I”]. This name cannot sound [from the outside] to our ear when it means our own self; it must arise from one's own soul life. All true religions have recognized this. This is an announcement of what is essentially the same in man as in the divine. Correctly understood, “I” means the ineffable name of God, because Yahweh, correctly translated, means “I am,” no matter what philology may otherwise interpret. This does not mean that man is to be made a god. Just as a drop of water is not the sea, so man is not God.

That which withdraws itself in the evening divides again into two parts: that which is the carrier of desires, passions, etc., and that which lets all these perceptions flow together in us and works through them - the I. Through the I, man becomes the crown of all creatures on this earth. But that which goes out at night is composed of the I and the astral body. What does a human being leave behind? The physical body, and we have that in common with every mineral. It consists of the same forces. The inanimate mineral, the crystal, takes its form from the forces within it; this is not the case with a living being. In the case of humans, we see that their physical body is subject to chemical laws only in one instance, and only at death. In death, we see what the forces imprinted on the mineral do to the body. In life, it never follows these forces. What remains in bed at night is imbued and permeated by another body, and we call this the etheric or life body. This prevents the body from following the chemical and physical laws; it is a faithful fighter against them.

Now we can ask ourselves: Why does this happen every evening, that a person must return to their spiritual home, so to speak? Why must they withdraw into a spiritual world every evening? In the evening, external impressions fade; we are overcome by fatigue. When the astral body and the ego withdraw into the spiritual world, the person falls into unconsciousness. The astral body is the carrier of pleasure and pain, urges, passions and so on. Why does all this disappear from our soul life? How can it be that all this dies away at night? We shall soon understand why this is so. The astral body and the I are the bearers of pleasure and pain, of perceptions and concepts. But in order for this to become conscious to the human being, it is necessary that they are mirrored by the physical body and the etheric body. We perceive nothing but what lives in ourselves. It is like a kind of echo that is produced in us by the physical and etheric bodies. Man does not perceive directly what he feels, but what he experiences is mirrored to him through the astral body and the I, through the etheric and physical bodies. But the work of the astral body involves conjuring up what we call the soul life. The real work is done by the astral body and not by the mirror – just as it is necessary for a person to be active at a mirror in order to create this or that image. The astral body has to work from morning till evening to extract from the physical what we can call the content of our soul. The forces that the astral body needs to work during the day, it must draw from the spiritual world. When these forces are exhausted, fatigue sets in, and it must draw new forces again.

Sleep has a profound significance. In the spiritual world is the source of everything we conjure up during our daily lives. If we look at our daily life in this way, we ask: What is the significance of our daily life if the soul has to draw its strength from the spiritual world? The soul and the ego do not enter the astral world empty, but take something with them from our outer world every evening. Life during the day is not without fruit for the soul's life. We need only look at what is characteristic of our soul in its deepest meaning and what is taken from our daytime life into our nighttime life. This can be seen indirectly when we look at our soul during our youth and in old age. This gives us an idea of development. In youth, we see germinal tendencies, but undeveloped, and later we see our soul transformed, with richer content. How can we transform ourselves? By the soul forming a kind of essence every evening from the external impressions we have received. We carry our daytime experiences into the night, and in the morning that which was the soul's spiritual experience has entered the soul; it joins what is already there, and in this way the soul develops.

You only have to look at people who cannot sleep, and if you are an attentive observer, you will notice how the soul's progress suffers when it cannot get the right amount of sleep. We can only imprint something on our memory if we have had a proper amount of sleep. Only in this way can we develop the forces that lead us ever higher. We imprint in our soul what the world reveals to us during our waking life, and in this way our soul becomes wiser. Knowledge is an important means of developing our soul between birth and death. But let us now ask ourselves how much transformation we can actually achieve. How narrow are the limits within which we find ourselves? We can increase our soul development. We can see this in individual abilities, for example in learning to write. Writing encompasses a whole group of abilities. When we look back, we see what a wide range of abilities were involved, how much work and effort and so on went into learning the art of writing. Or think of the first attempt we made to draw the first letter, of everything that then flowed together into the one skill of writing. From what we experienced then, we extracted an essence, and through such weaving together a soul skill arises.

Whatever has a deeper impact on our lives can only develop within very narrow limits in the time between birth and death. If someone pursues the riddles of the world or has gone through this or that life experience in deep pain, you can even see that reflected in their physiognomy and in their movements. From decade to decade, this is expressed more and more, even in the body. But we can develop in this direction only to a limited extent. Why? Because we have our souls before us like a malleable material, but we cannot work with what our inclinations have created between birth and death into the body, no matter how many experiences we have gathered. Let us take the example of music. If we do not have a finer ear, if we are not musical, we are unable to develop the ability during our lifetime that could change our physicality in this respect between birth and death. We are powerful in the face of the soul, but powerless in the face of the facts of our physicality. But we know that when we face the external world and conjure up all these images, they are born out of our soul - not only, but through its activity, because it could never conjure up such reflections if something were not given from outside. And this outside includes the same forces that make up our physical body. It seems so mysterious to us because we cannot penetrate there. We would have to conjure up a fine musical ear and so on from the same world. It is something like a veil, like a shell. But behind it is something that, if we could master it, would give us the ability to transform our physical body just as much as the astral.

We can gain knowledge, but we cannot utilize it; we cannot transform our body with the knowledge. But there is a possibility to transform our physical body in the same way as the astral one. Even if we recognize the forces, we could not apply them directly, because our physical and etheric bodies are given to us as dense material. Here we want to refer to a law that will be incorporated into modern spiritual life through Theosophy.

In the 17th century, not only laymen but also naturalists believed that worms and fish could arise from mud. If we go back to the 17th century, we find scholarly works that describe how wild animals grew out of other animals – for example, hornets out of a dead ox that had been beaten until it was brittle, bees out of a horse carcass, and wasps out of a donkey carcass. It was [the naturalist] Francesco Redi who first uttered the sentence: Living things can only arise from living things. There must be a germ of something living in order for something living to arise. Redi was almost burned [as a heretic] for saying this. Today, anyone who claims otherwise would be considered backward. Spiritual science says: Spiritual-soul things can only arise from spiritual-soul things. Just as an earthworm does not come from mud, so the spiritual does not come from the inheritance of the father and mother.

We have to distinguish between the environment of the spiritual and the spiritual itself. In spiritual science, this leads us to the law of reincarnation [of what lives spiritually in man]. Today those who have recognized this law are perhaps not exactly called heretics – fashions change. Today the [true] enlightened are declared to be fantasists, dreamers. But in the not too distant future, people will no longer be able to understand how anyone could have believed otherwise. Thus, we see in what comes into existence through birth the repetition of an earlier earthly existence. And what lies between death and birth is a purely spiritual existence. When we look at a child with undeveloped features, we see what it has brought with it from previous lives on earth, and we can understand something that is very important.

Why can we only develop mental abilities during our lifetime? When we wake up, we find the same body with the same organs. But when a person passes through the gate of death, the great moment arrives when he discards his physical body and only what is spiritual and mental remains. Now he is no longer bound to the body. The conditions are quite different than during sleep. In the morning, when we wake up, we find the same physical body; we cannot destroy it and rebuild it. But when the physical falls away at death, what we have taken in knowledge during our life is united with our soul. In accordance with the knowledge and experiences we have had, we can now reshape them and incorporate them into a new body.

Thus, in each life, we build our body according to what we have gained in the last life; we make it the product of our experiences in the last life. Life experience in the present life is our existence in a next life. This is how knowledge works in us; it is one of the most important forces of existence, shaping itself. We are grateful for the knowledge of the last life; it has produced a body in the present life and preserves that with which we have enriched ourselves in the present life, and that will bring us higher in the next life. Now we also understand why there can be a huge difference between different people when we consider the strength and weakness of their cognitive abilities.

Now you will ask: why does man not remember his previous lives? That is also a matter of development. A four-year-old child cannot count. But it would be a false conclusion to say that this is not a human being, because humans can count. Wait until he is ten years old. There comes a time for every person when he begins to remember. One can only remember that which is present. Fichte was right to say that most people would rather consider themselves a piece of lava on the moon than a self. The realization of what the self is is still missing. Just as the flowers can only be recognized through sensory impressions, so can the spiritual only be recognized through spiritual research. From the intimate study of the self, it follows that the self must be there as a conscious idea before one can remember. Only when we have generated the idea of self can we reflect back on ourselves. Thus, knowledge as self-knowledge leads us to build up our memory in such a way that we consciously expand life beyond the life that is enclosed between birth and death. If we can continue to work from life to life, if through knowledge we succeed in shaping ourselves and thus awaken the eternal in us, then the knowledge of development helps us in the shaping of all that is eternal in us. Now we give the work of knowledge and its meaning for our whole life. It brings us immortality and gives us knowledge of our immortality.

Immortality and knowledge belong together. In a particular life, our body appears to be something that has been worked into it from the previous life. We often cannot use the knowledge in this life, but we need it to build a new body. This certainty gives spiritual science a practical meaning in life. It must not remain mere theory, but we must permeate ourselves with it completely. We then see death in a new light. Knowledge has built up our present body. Through the disintegration of our body, we become free from it and gain the opportunity to build a new one. Thus, even if we look at death in pain when it touches others, or with fear when it approaches us, it appears to us in a completely different form. If we can rise to a higher point of view, we can say that we are grateful for death, because it gives us the opportunity to build a new body for ourselves - for a higher life. The old spiritual researchers have always recognized this and also said so. Goethe puts it so beautifully in front of our soul, how we bring in from fresh life what we have worked for in the previous life:

As on the day when you were given to the world
The sun stood in greeting of the planets,
You immediately thrived and thrived
According to the law by which you entered.
So you must be, you cannot escape yourself,
So the Sibyls said, so the prophets said;
And no time and no power can dismember the form that has been stamped, which develops itself alive.
