II. Oswald Spengler I

This definite kind of thinking is what humanity has achieved since the time of Galileo and Copernicus. It shows first that man can grasp by means of it only lifeless, inorganic nature; but that, on the other hand, only by yielding himself to it, as to the simplest and most primitive kind of pure thinking, can he develop freedom of the human soul, or any kind of freedom for man. Only one who understands the character of clear, objective thinking, as it holds sway in lifeless nature, can later rise to the other processes of thinking and of seeing—to that which permeates thought with vision, with inspiration, with imagination, with intuition.
