Do your duty, and leave the rest to heaven.

The line urges a stoic, duty-centered ethic: act according to what is right and within your control, and relinquish anxiety about outcomes to a higher providence. It frames moral action as an obligation independent of success, reward, or public approval—once duty is fulfilled, the rest belongs to forces beyond human command (“heaven,” i.e., God, fate, or providence). In a Corneillean register, this aligns with the tension in his tragedies between personal desire and honor, where characters are often judged by steadfastness and integrity rather than by the external results of their choices. The aphorism thus functions as counsel for ethical clarity under uncertainty.
