Is it really true that no matter how much theory they accumulate, what humans really yearn for is experience?

I hear that even Einstein didn't believe his own quantum theory.

That, and he also didn't believe in an expanding universe at first, and doubted the existence of black holes...

Being compared to our cognition, perception, and five senses is how theory gets its meaning.

The human world-view is built on feelings, right? Although, that practicality went too far at one time, to the point that high-end research started to stagnate.

For better or worse, that's one of its effects. People just can't find value in theory they can't experience.

Human perception being narrow is what allows one to peek into the realm of faith and mystery. And because we can feel the synthetic world, we convince ourselves it's real.

To look with one's eyes is a special act.

With our individual mind and judgment, we draw borders in a world of continuities.
