Thirteenth Lecture

What the natural scientists themselves develop is certainly ingenious, useful, and conscientiously methodical, but only for the external world. Today, everyone works in their own field and does not extend the concepts that are developed in any field to the totality of the human world view. Take just one example, and you will immediately understand what I actually mean. The ordinary school physicist who today looks at the magnet needle pointing with one end to the north and with the other to the south, explains to his boys that this constant pointing of the magnet needle to the north and to the south comes from the earth's magnetism, that the earth is also a great magnet; and it would be ridiculous if this school physicist were to seek in the magnet needle itself the forces that cause the needle to point in these directions. He tries to explain it in terms of the properties of the earth; he seeks the cause outside in the cosmos. In this purely dead area, the scientific concepts are still of some use, and one or other of them may still be discovered. Therefore, it does not occur to anyone to say of the magnetic needle that it has the inherent power to always point in one direction. One assumes directional forces from the magnetic north and south poles of the earth. The biologist no longer does this. It does not occur to him to develop a similar concept. The biologist sees the chicken in which the egg is formed. It does not occur to him to ask the same question as the physicist asks about the magnetic needle. The biologist simply says: When the egg is formed in the hen, the cause of the egg formation lies in the hen. If he were to proceed as the physicist does with the magnet needle, he would say: Although the hen is the place where the egg is formed, the cosmic forces are involved in the same way as the cosmos is involved in the magnet needle when the egg is formed. I must go beyond the narrow confines of nature and take what is outside to help. In the chicken there is the place where the egg develops, but the forces come from the cosmos, just as they give direction to the magnet needle from the cosmos.
