15. The Theory of Categories

The concepts also are really only an obliteration of the super-sensible reality, and because they resemble the spiritual world, as the shadow-pictures do the prototypes, for this reason the human being can form an inkling of the super-sensible worlds. When the perception of the super-sensible makes concept with the sensible, then these shadow-pictures arise. In the conceptual shadow-pictures you have the super-sensible reality just as little as in the shadow-picture of the hand you have the hand itself. Accordingly we have recognized here that the concepts are the boundary between the two realities, but originate from the super-sensible reality.
