III. Understanding the Human Being: A Foundation for Education

There is another difference that brings us closer to an understanding of the difference in duration. If we expose the eye to a color impression and then see an after-image, it is something partial, an individual organ on the periphery of the human organism that brings forth that after-effect. When a memory arises from within the human being, it reproduces something that existed years before. This is something we can feel, that is apparent, that participates in this reproducing—thus it is the entire human being that participates in this after-effect.
