“Those who do not move, do not notice their chains.”
Rosa Luxemburg (1871–1919) Polish Marxist theorist, socialist philosopher, and revolutionary

Context: I was polishing a brandy snifter when the Unmarried Mother came in. I noted the time — 10: 17 P. M. zone five, or eastern time, November 7th, 1970. Temporal agents always notice time and date; we must.
The Unmarried Mother was a man twenty-five years old, no taller than I am, childish features and a touchy temper. I didn't like his looks — I never had — but he was a lad I was here to recruit, he was my boy. I gave him my best barkeep's smile.
“True progress quietly and persistently moves along without notice.”
