When the thing observed... is seen as an agglomeration of pieces, the details lose their meaning and the whole becomes unrecognizable. This is often true of snapshots in which no pattern of salient shapes organizes the mass of vague and complex nuances.

The dance, just as the performance of the actor, is kinesthetic art, art of the muscle sense. The awareness of tension and relaxation within his own body, the sense of balance that distinguishes the proud stability of the vertical from the risky adventures of thrusting and falling--these are the tools of the dancer.

Variety is more than a means of avoiding boredom, since art is more than an entertainment of the senses.

Good art theory must smell of the studio, although its language should differ from the household talk of painters and sculptors.

Now the work of art also represents a state of final equilibrium, of accomplished order and maximum relative entropy, and there are those who resent it. But art is not meant to stop the stream of life. Within a narrow span of duration and space the work of art concentrates a view of the human condition; and sometimes it marks the steps of progression, just as a man climbing the dark stairs of a medieval tower assures himself by the changing sights glimpsed through its narrow windows that he is getting somewhere after all.

All perceiving is also thinking, all reasoning is also intuition, all observation is also invention.

A system is in equilibrium when the forces constituting it are arranged in such a way as to compensate each other, like the two weights pulling at the arms of a pair of scales.
