8. What is Mortal in Man?

One will only admit this if one has already grasped the nature of the spiritual. For, of course, from the present state of natural science, one can easily say: Yes, movement transforms into warmth, as physical research shows us; why shouldn't external processes transform into sensation and thought within us? Of course they do. They do it by evoking processes that are the mirror in which our being is reflected. One can say: natural science is quite right. Only by fully embracing natural science and not fighting it, but then also asserting spiritual experiences, can one make progress. So someone might say: So the spiritual processes are a transformation of the external processes. Just as movement is transformed into warmth, so that which is outside in the world is transformed into that which is within us. But this was only valid as long as it could not be proven that when we transform movement into warmth, something always remains that is there, always there. That has remained warmth, is never anything but warmth. This is apparent to someone who really follows the bodily process from outside his body, who follows what the body can actually do. It is apparent to him that although, when we perceive in the external world, the process that is built up by the senses and continues in the brain is a continuation of the external process, this is not correct in relation to what we remember. And it is precisely at this point that the ever-advancing science will show that, by focusing attention on the physical processes, the process of memory, which is a purely spiritual process, could never somehow arise from the physical processes. It will be possible to show, in a strictly scientific way, that what happens physically in us when we remember is not the mental process, or has more to do with it than the strokes of a pen on paper have to do with what I read. When I have a word consisting of certain lines in front of me, I do not read by looking at the word and tracing my thoughts, but by connecting a meaning with this sign through something in me that has nothing to do with what is on the paper. Thus one will come to realize that the memory process that takes place in the body has as little to do with physical processes as my reading process has to do with the forms on the paper. Memory will present itself as a spiritual process that intervenes in physical life. But then one will also recognize that already in our ordinary physical life between birth and death we are surrounded by the essence that we must grasp in a higher, more intense sense if we want to look towards the immortal. When materialism asks: What is mortal in man? and answers: Everything that man experiences here in the sense world! — then spiritual science can also say to him: Yes, you are right; everything that a person experiences here in the world of the senses is mortal in the human being. But just as an event passes by in our physical life and we remember it at a later point in time purely through the spiritual essence of our soul, so too is it with our soul. As long as we are searching for a “soul substance,” we are incapable of even approaching that which is immortal in the human being. As soon as we know that what is not even noticed in our ordinary mortal existence because it is as if a person stands before a mirror and sees only his reflection, only knows himself in the image, — as soon as we know that what what is ignored in ordinary life, what we know nothing about in ordinary life, what we only know as in an image, - that precisely this is what is retained after our death and lives in the memory of earthly life, we can also understand: What we are here, it goes as a fact, as that, as what it lives here, perishable in the human being. That which remains for the soul, the soul that does not know itself in life, that is the memory that will be incorporated into the experiences that the human being then undergoes in the purely spiritual world after death.
