As a child, I was always asking those why questions. When I was a junior high school student, I was reading the scientific commentary part of a new book. I was very interested in the theory of relativity, but I couldn't understand it, and I was dissatisfied with the denial of the Newtonian view of the world. One book wrote, ""Asking why is a childish attitude to doing science. It is the science that finds out what the world is like."" Scientific attitude is, at the very least, the discovery and examination of sub propositions hidden in asking the truth of propositions. Science develops by the exploration and arrangement of its sub propositions.
