Dancing is surely the most basic and relevant of all forms of expression. Nothing else can so effectively give outward form to an inner experience. Poetry and music exist in time. Painting and architecture are a part of space. But only the dance lives at once in both space and time In it the creator and the thing created, the artist and the expression, are one. Each participant is completely in the other. There could be no better metaphor for an understanding of the… cosmos.
We begin to realize that our universe is in a sense brought into being by the participation of those involved in it. It is a dance, for participation is its organizing principle. This is the important new concept of quantum mechanics. It takes the place in our understanding of the old notion of observation, of watching without getting involved. Quantum theory says it can’t be done. That spectators can sit in their rigid row as long as they like, but there will never be a performance unless at least one of them takes part. And conversely, that it needs only one participant, because that one is the essence of all people and the quintessence of the cosmos.
