Sam Dresser in Aeon:
If the idea of freedom bound Camus and Sartre philosophically, then the fight for justice united them politically. They were committed to confronting and curing injustice, and, in their eyes, no group of people was more unjustly treated than the workers, the proletariat. Camus and Sartre thought of them as shackled to their labour and shorn of their humanity. In order to free them, new political systems must be constructed.
In October 1951, Camus published The Rebel. In it, he gave voice to a roughly drawn ‘philosophy of revolt’. This wasn’t a philosophical system per se, but an amalgamation of philosophical and political ideas: every human is free, but freedom itself is relative; one must embrace limits, moderation, ‘calculated risk’; absolutes are anti-human. Most of all, Camus condemned revolutionary violence. Violence might be used in extreme circumstances (he supported the French war effort, after all) but the use of revolutionary violence to nudge history in the direction you desire is utopian, absolutist, and a betrayal of yourself.
‘Absolute freedom is the right of the strongest to dominate,’ Camus wrote, while ‘absolute justice is achieved by the suppression of all contradiction: therefore it destroys freedom.’ The conflict between justice and freedom required constant re-balancing, political moderation, an acceptance and celebration of that which limits the most: our humanity. ‘To live and let live,’ he said, ‘in order to create what we are.’
