Motion can be seen in two ways: that which makes one thing go away from another, and that which makes one thing go towards another. (Makes here doesn’t mean causes.)

Motion, further, can be seen as within, of parts; and without, of wholes.

For example, if a thousand pebbles were in a bucket, moving about, and rubbing against themselves, an idea of warmth would be present more than in those thousand pebbles moving in an area of four square miles. In the bucket, there would be much bobbing and dancing and going up and down of pebbles; the smaller the bucket, with the presence of just as much motion, would make for so much more warmth. If the pebbles are thought of as not being able to move at all, there is less warmth. Warmth implies compactness and movement.

When one thinks of warmth, one thinks of a whole having moving details or parts in it. There would be no life without warmth. Warmth is the very basis of chemistry. The closeness or oneness, along with the motion of warmth, is like the junction of oneness with detail in aesthetics. Chemistry, it follows, is like aesthetics.

In popular speech, to be close to one also means to be “warm” to one. However, for a person to be close to one without moving or talking or animation, would hardly be showing warmth. Two persons close to each other, but not in motion in any way make for less warmth than two persons less close, but acting on each other. So it is the feeling of closeness with the presence of motion or activity that makes the warmth. Warmth, in social life, is like warmth otherwise. It is closeness and activity or motion.
