"A man can do only what he can do. But if he does that each day he can sleep at night and do it again the next day"
About this Quote
The subtext is a rebuke to two temptations common to conscientious people: the savior complex and the self-excusing despair. Schweitzer, a theologian who became famous for turning ethics into lived practice (medicine, humanitarian work, “reverence for life”), knew how easily moral ambition becomes an alibi. If you aim for the heroic, you’ll always have an excuse for doing nothing today: the task is too big, the system too broken, your contribution too small. Schweitzer replaces the heroic with the sustainable.
“Sleep at night” is doing more work than it appears. It’s not about comfort; it’s about the kind of peace that comes from integrity, not outcome. Results are volatile. Conscience is steadier. In an era shattered by industrial war and colonial violence, Schweitzer’s minimalism reads as both spiritual counsel and pragmatic survival strategy: accept limits, keep faith with the daily duty, return tomorrow. The ethic is less triumph than endurance.
