The danger of success is that it makes us forget the world’s dreadful injustice.

Renard’s line warns that personal advancement can dull moral perception. Success often brings comfort, status, and insulation from hardship; as one’s life becomes easier, the suffering and structural unfairness that shape others’ lives can fade from view. The “danger” is not success itself but the complacency and selective attention it can produce—an ethical amnesia in which privilege is mistaken for normality and injustice becomes abstract. The remark also implies a responsibility for the successful: to resist the narrowing of sympathy, to keep contact with realities outside one’s circle, and to use influence without losing clarity about the world’s inequities.
