“If it is possible, as far as it depends on you, live at peace with everyone.” Romans 12:18
“As far as possible without surrender, be on good terms with all persons.” Max Ehrmann – Desiderata
Written a few centuries apart, but the same sentiment. The “as far as it depends on you” and “without surrender” are key phrases. “Peace,” at times, seems aspirational, and détente is the best one can achieve.
