So, first we have the outer spectrum, and on this outer spectrum we have the undertone of the soul experiences. We are thus confronted with the outer world through our senses, through our eyes, and we cannot adjust the eye differently, except that, even if often unconsciously or subconsciously, soul experience is involved. We call what is experienced through the eye a sensation. We are now accustomed, ladies and gentlemen, to calling the sensation experienced something that is experienced by the soul – that is, an impulse that comes from what is objectively spread out and presents itself as a sensation – something subjective. But you can see from the way I have just presented this in reference to Goethe that we can, so to speak, set up a counter-spectrum, a soul counter-spectrum, that can be precisely paralleled with the outer optical spectrum.
