no adequate cause exists either inside or outside of his body. A particular source must be found for everything in this domain; and according to occult science this source is to be found in the human “I” or “ego.” Therefore the ego will be spoken of as the fourth principle of the human being.
Were the astral body left to its own resources, feelings of pleasure and pain, and sensations of hunger and thirst, would take place within it, but there would be lacking the consciousness of something lasting in all these feelings. It is not the permanent as such, which is here designated the “ego,” but rather that which experiences this permanent element. In this domain, conceptions must be very exactly expressed if misunderstandings are not to arise. With the becoming aware of something permanent, lasting, within the changing inner experiences, begins the dawn of “ego consciousness.”
The sensation of hunger, for instance, cannot give [pg 026] a creature the feeling of having an ego. Hunger sets in when the recurring causes make themselves felt in the being concerned, which then devours its food just because these recurring conditions are present. For the ego-consciousness to arise, there must not only be these recurring conditions, urging the being to take food, but there must have been pleasure derived from previous satisfaction of hunger, and the consciousness of the pleasure must have remained, so that not only the present experience of hunger but the past experience of pleasure urges the being to take nourishment.
Just as the physical body falls into decay if the etheric body does not keep it together, and as the etheric body sinks into unconsciousness if not illuminated by the astral body, so the astral body would necessarily allow the past to be lost in oblivion unless the ego rescued the past by carrying it over into the present. What death is to the physical body and sleep to the etheric, the power of forgetting is to the astral body. We may put this in another way, and say that life is the special characteristic of the etheric body, consciousness that of the astral body, and memory that of the ego.
It is still easier to make the mistake of attributing memory2 to an animal than that of attributing [pg 027] consciousness to a plant. It is so natural to think of memory when a dog recognizes its master, whom perhaps it has not seen for some time; yet in reality the recognition is not due to memory at all, but to something quite different. The dog feels a certain attraction toward its master which proceeds from the personality of the latter. This gives the dog a sense of pleasure whenever its master is present, and every time this happens it is a cause of the repetition of the pleasure. But memory only exists in a being when he not only feels his present experiences, but retains those of the past. A person might admit this, and yet fall into the error of thinking the dog has memory. For it might be said that the dog pines when its master leaves it, and therefore it retains a remembrance of him. This too is an inaccurate opinion. Living with its master has made his presence a condition of well-being to the dog, and it feels his absence much in the same way in which it feels hunger. One who does not make these distinctions will not arrive at a clear understanding of the true conditions of life.
[pg 028]
Memory and forgetfulness have for the ego much the same significance that waking and sleeping have for the astral body. Just as sleep banishes into nothingness the cares and troubles of the day, so does forgetfulness draw a veil over the sad experiences of life and efface part of the past. And just as sleep is necessary for the recuperation of the exhausted vital forces, so must a man blot out from his memory certain portions of his past life if he is to face his new experiences freely and without prejudice. It is out of this very forgetfulness that strength arises for the perception of new facts. Let us take the case of learning to write. All the details which a child has to go through in this process are forgotten. What remains is the ability to write. How would a person ever be able to write if each time he took up his pen all his experiences in learning to write rose up before his mind?
Now there are many different degrees of memory. Its simplest form is manifest when a person perceives an object and, after turning away from it, retains [pg 029] its image in his mind. He formed the image while looking at the object, A process was then carried out between his astral body and his ego. The astral body lifted into consciousness the outward impression of the object, but knowledge of the object would last only as long as the thing itself was present, unless the ego absorbed the knowledge into itself and made it its own.
It is at this point that occult science draws the dividing line between what belongs to the body and what belongs to the soul. It speaks of the astral body as long as it is a question of the gaining of knowledge from an object which is present. But what gives knowledge duration is known as soul. From this it can at once be seen how close is the connection in man between the astral body and that part of the soul which gives a lasting quality to knowledge. The two are, to a certain extent, united into one principle of human nature. Consequently, this unity is often denoted the astral body. When exact terms are desired, the astral body is called the soul-body, and the soul, in so far as it is united with the latter, is called the sentient soul.
The ego rises to a higher stage of its being when it centres its activity on what it has gained for itself out of its knowledge of objective things. It is by means of this activity that the ego detaches itself more and more from the objects of perception, in order to work within that which is its own possession. The part of the soul on which this work [pg 030] devolves is called the rational- or intellectual-soul.3 It is the peculiarity of the sentient and intellectual souls that they work with that which they receive through sense-impressions of external objects of which they retain the memory. The soul is then wholly surrendered to something which is really outside it. Even what it has made its own through memory, it has actually received from without. But it is able to go beyond all this, and occult science can most easily give an idea of this by drawing attention to a simple fact, which, however, is of the greatest importance. It is, that in the whole range of speech there is but one name which is distinguished by its very nature from all other names. This is the name “I.” Every other name can be applied by any one to the thing or being to which it belongs. The word “I,” as the designation of a being, has a meaning only when given to that being by himself. Never can any outside voice call us by the name of “I.” We can apply it only to ourselves. I am only an “I” to myself; to every one else I am a “you,” and every one else is a “you” to me. This fact is the outward expression of a deeply significant truth. The real essence of the ego is independent of everything outside of it, and it is on this account that its [pg 031] name cannot be applied to it by any one else. This is the reason why those religions confessions which have consciously maintained their connections with occult science, speak the word “I” as the “unutterable name of God.” For the fact above mentioned is exactly what is referred to when this expression is used. Nothing outward has access to that part of the human soul of which we are now speaking. It is the “hidden sanctuary” of the soul. Only a being of like nature with the soul can win entrance there. “The divinity dwelling in man speaks when the soul recognizes itself as an ego.” Just as the sentient and intellectual souls live in the outer world, so a third soul-principle is immersed in the divine when the soul becomes conscious of its own nature.
In this connection a misunderstanding may easily arise; it may seem as though occult science interpreted the ego to be one with God. But it by no means says that the ego is God, only that it is of the same nature and essence as God. Does any one declare the drop of water taken from the ocean to be the ocean, when he asserts that the drop and the ocean are the same in essence or substance? If a comparison is needed, we may say, “The ego is related to God as the drop of water is to the ocean.” Man is able to find a divine element within himself, because his original essence is derived directly from the Divine. Thus man, through the third principle of his soul, attains an inner knowledge of himself, just as through his astral body he gains knowledge of the outer world. For this reason occult science [pg 032] calls the third soul-principle the consciousness-soul, and it holds that the soul-part of man consists of three principles, the sentient-, intellectual-, and consciousness-souls, just as the bodily part has three principles, the physical, etheric, and astral bodies.
The real nature of the ego is first revealed in the consciousness-soul. Through feeling and reason the soul loses itself in other things; but as the consciousness-soul it lays hold of its own essence. Therefore this ego can only be perceived through
