Sartre began by writing to tell Merleau-Ponty that a person who was no longer ‘engaged’ politically should not expect to criticise those who were. You are right, Merleau-Ponty replied. Indeed, he has now decided never again to issue hasty responses to events as they occur. After Korea, he has concluded that one needs a longer perspective to understand history. He no longer wishes to ‘become engaged on every event, as if it were a test of morality’ — a tendency which he describes as bad faith.
