Lecture I
In the coming lectures I will be speaking of a comparison, that to begin with I would like you to consider as an analogy. When we permeate empirical facts with mathematics, our activity consists of two stages: First we must look at the empirical facts, let's say the facts of the eye. The second is the arrangement of these percepts into mathematical formulas. In a certain way, as a result of this we have essentially an experience of mathematical formulating. We no longer view the empirical world of phenomena. This process can be compared to our inhaling life-sustaining oxygen; we saturate our whole organism with it. The oxygen then combines with carbon and we exhale carbon dioxide, which is no longer the life-sustaining air. But the combined process was necessary for our inner life. We had to inhale the life-strengthening oxygen and combine it with something in us. What is produced in this way is something killing; we can contrast it with what was inhaled, which was life-sustaining.
