Answer
Sartre's philosophy aligns with individualism and personal authenticity. Aron, though a lifelong friend and intellectual comrade, believed that Sartre's existentialism led to moral irresponsibility. Aron contended that it was better to be "right with" himself, acknowledging moral obligations and social norms, rather than being "wrong with Sartre," embracing unfettered individualism without regard for the consequences of one's actions.
