The Christian philosophical framework of the West created an environment where rationalism could grow and flourish. Eventually rationalism became parasitic and killed its host. But now, without any framework of its own to start from, rationalism has no anchor from which to carry out deduction and therefore drifts into nihilism. At the same time, its promise of grand overarching narratives that explain everything has fallen short. The thinkers of the age elucidated these fatal flaws a half-century ago. Now the great minds of science encounter a reality where every answer poses multiple new questions, and knowledge must be coupled with mystery and wonder. The doers of this age came to grips with the fading phantom of perfect knowledge and resolved to act anyway with the limited understanding they have, a leap of faith if you will.
So, things come full circle. The default folk philosophy which was Christian in previous ages is now based upon a rationalism that itself is obsolete. Pascal described this a long time ago. He agreed that God does not reveal himself through objective evidence. He called the atheist intellectually lazy because he refuses to consider whether God might reveal himself through other means.
