The "complete system of relevant perception" is the standard human experience of a work of art. It takes many successive perceptions to approach the full perception of the work. If a person wishes to appreciate the picture he has to get rid of irrelevancies. But barring irrelevancies, a spectator in his first perception can hardly see more than a few of the traits that belong to the picture. Seeing it frequently, however, he begins to understand little by little the full richness of the picture. He remembers what he has seen in it before and adds this to what he finds in it afresh, so that each successive perception gets richer and richer. This process of fusing one's memories of former perceptions into the present one is called funding. Past appreciations are added to the present which goal is the full understanding and appreciation of an aesthetic work of art. The final funding of all the relevant details in a single perception or system of perceptions is the standard aesthetic work of art. A spectator may never quite attain it. However, if a spectator clears his perceptions of irrelevancies, he is always in contact with some part of the structure of the aesthetic work of art.
Everytime we learn to appreciate one work of art richly, it helps us to appreciate another one more quickly. For wherever aesthetic works of art have traits in common, relevant funding may go on from one work to another.
