Lecture II

Such thinkers forget but one thing: they forget—and it is just this that we want to indicate in the course of these lectures with all the forceful proofs we can muster—that the natural order governing the construction of our head also governs the construction of the regular polyhedrons, and it is for just this reason that our head constructs no other polyhedrons than those that actually confront us in the external world. For that, you see, is one of the basic differences between the so-called subjective qualities of tone, color, warmth, as well as the different qualities of touch, and that which confronts us in the mechanical-mathematical view of the world. That is the basic difference: tone and color leave us outside of ourselves; we must first take them in; we must first perceive them. As human beings we stand outside tone, color, warmth, etc. This is not entirely the case as regards warmth—I shall discuss that tomorrow—but to a certain extent this is true even of warmth. These qualities leave us initially outside ourselves, and we must perceive them. In formal, spatial, and temporal relationships and regarding weight this is not the case. We perceive objects in space but stand ourselves within the same space and the same lawfulness as the objects external to us. We stand within time just as do the external objects. Our physical existence begins and ends at a definite point in time. We stand within space and time in such a way that these things permeate us without our first perceiving them. The other things we must first perceive. Regarding weight, well, ladies and gentlemen, you will readily admit that this has little to do with perception, which is somewhat open to arbitrariness: otherwise many people who attain an undesired corpulence would be able to avoid this by perception alone, merely by having the faculty of perception. No, ladies and gentlemen, regarding weight we are bound up with the world entirely objectively, and the organization by means of which we stand within color, tone, warmth, etc. is powerless against that objectivity.
