Lecture II

For example, we find among them physicists and chemists who have learnt the laws governing the combination and separation of substances; there are zoologists who have learnt how one examines and describes animals; there are doctors who have learnt how to treat the physical human body, and what they themselves call the soul. What do they all do? They say: When a person wants to work out for himself a conception of the world, then he takes the laws that are learnt in chemistry, in physics, or in physiology—no others are admissible—and out of these he builds a conception of the world for himself. These people proceed exactly as the hypothetical shoemaker would have done if he had constructed the world-boot, only they do not notice that their world-conceptions come into existence by the very same method that produced the hypothetical world-boot. It does certainly seem rather grotesque if one imagines that the difference between day and night comes about through the soiling of shoe-leather and the repolishing of it in the night. But in terms of true logic it is in principle just the same if an attempt is made to build a world out of the laws of chemistry, physics, biology and physiology. Exactly the same principle! It is an immense presumption on the part of the physicist, the chemist, the physiologist, or the biologist, who do not wish to be anything else than physicist, chemist, physiologist, biologist, and yet want to have an opinion about the whole world. The point is that one should go to the root of things and not shirk the task of illuminating anything that is not so clear by tracing it back to its true place in the scheme of things. If you look at all this with method and logic, you will not need to be astonished that so many present-day conceptions of the world yield nothing but the “world-boot”. And this is something that can point us to the study of Spiritual Science and to the pursuit of practical trains of thought; something that can urge us to examine the question of how we must think in order to see where shortcomings exist in the world.
