Camus concludes that Kierkegaard and a phalanx of other seers have committed intellectual hari-kari by first recognizing human existence for the madhouse that it is, and then mentally constructing an apparatus like faith in God to put everything in order and make some semblance of sense of their lives.
Partially true: We do try to construct faith to make sense of the world. We want to understand everything. However, we cannot understand everything. But it seems to me that salvific faith is "the gift" of God, which is "faith in God."
