Man is lazy. He does not want to do anything. Even if only it is to move his little finger, man only does something out of necessity. If I have no choice, then I run around, do all sorts of things, wake up in the morning to go to work, all in order to obtain something. I have no choice in this. Nature exerts pressure on us and compels us to move. This is called “unconscious development.” It occurs out of necessity, as in any other part of nature. This is exactly how molecules and atoms all interconnect; all the processes in nature take place only under the influence of pressure on all possible levels and degrees.
