i disagree. many readers mistakenly assume that the main character’s “sleepwalking through life” behavior is being presented as normative or ideal by camus. in fact the opposite is true, because at the very end of the book as he is awaiting execution in a jail cell he experiences a sudden realization that life does have a purpose after all – the purpose of life is life itself.
ironically, he needed to stare the hangman in the face to make him realize that life is worth living, but camus is saying most people are similarly oblivious. i never “got” this book until this was pointed out to me, after which it all made sense.
there is a similar “jail cell conversion” scene in the final chapters of “the red and the black” by stendahl, which probably influenced camus.
if you read the protagonist as an antihero, the novel ends on a life affirming note that is in marked contrast to the rest of the book. camus is often seen as the sunnier face of existentialism (in contrast to sartre) for this, and while i’m sure he was no catholic, i like to think the life-affirming ending of the book makes him something of a crypto-catholic.
