Being quiet, at rest, still, motionless, as in quiescent thoughts.
There is a brief time for sex, and a long time when sex is out of place. But when it is out of place as an activity there still should be the large and quiet space in the consciousness where it lives quiescent. Old people can have a lovely quiescent sort of sex, like apples, leaving the young quite free for their sort.
—D. H. Lawrence The Letters of D. H. Lawrence (1932)
