In “the Myth of Sisyphus”, Camus forms the argument that Sisyphus has found happiness within his eternity of pushing a rock up a hill. After finally letting go of his memories of life, he accepts his current situation and finds joy in completing the hard task of pushing the rock up the hill (even though it falls down again).
In the Stranger, Merseaux states that after he lets go of the pleasures of the past and adapts to prison, it is actually quite enjoyable. It takes a bit of time to adjust, but eventually he does.
The question I that I pose is: is finding this happiness an inevitability for everyone? If so, is finding that joy in punishment then just a matter of time?
I would argue that it is not an inevitability for everyone. Some people will never let go of the memories and pleasures that they used to enjoy. They will always reap in their belief that they should be somewhere else.
