An example of this triadic arrangement is the established artist. The triad includes the artist, the buyer of the artist's art, and... Back track a moment. First we have the pro and the con, the negative and positive, the good and the bad, that is --- the creator and the consumer. Both essential, both obvious once you investigate, but are these two forces, flows, (to use Jan's words) sufficient for existence, for anything to happen? At first you think, perhaps, of course. What more do you need basically, except an artist and someone to buy the art? No buyer, the artist dies of starvation, so both are critical, and yet, are these two flows, the creative and the destructive, C and D flows, creator and consumer, a sufficient telling of the story?
A third force is necessary for the art world to exist. The binary mind can only count to two. But pushing the boundaries you can glimpse a third in every situation. Why three, and not more. Well dear ones, 'three' itself is a fiction, there are many more, but----getting the mind to count above two is a necessary step and itself sufficient to challenge the absurd presumptions of the ordinary mind, and three is about all that can be verbally encompassed.
In the case of the artist what is the third flow, what critical element, necessary for the other two forces to interact, what third force, necessary for a stable, even if stable means just for a moment, is relevant when discussing art?
The erelevant force in this example, is labeled, in the modern world, a curator.
This commissioning element, is like the mechanical mind's assumption that it, the personal mind, is the source of its own thoughts, in another triad, essential to the stability of the event we call art.
