Motion, that is, movement or locomotion, is necessary to perceive our environment. Thinking evolved from mapping out space: finding what the environment affords and pursuing goals based on your previous location.
The reversal is when we think we move: if anxious or neurotic, we compulsively fidget.

We are (mostly) not coerced to move for survival. Instead, we have internalized the threat of expulsion and channeled it into ambitious energy, productivity, and discontent… often marked by a compulsive twitchiness.
