Of all the wars that have taken place wince then, none has endured so long as the conflict between knowledge and belief. For centuries now, knowledge has attempted, unsuccessfully, to supersede belief. But the entire clash stems from a misapprehension of the nature of belief. We can't not believe; and we won't ever know everything. We know this much: knowledge remains an endless advance toward an end point that endlessly recedes.

The twentieth century prided itself on invalidating the metaphysical. Doubts about the afterlife arose even as so-called nonbelievers attempted to locate surrogates for the loss of meaning atheism occasioned. Enraptured with progress, we deepened our collective worship of science. As incredulity to metanarratives rose, so did a massive publicity campaign to convince us of the omnipotence of science.
