Humans are unavoidably limited and fallible. IMO, two of the screamingly obvious limitations are our inabilities to understand the nature of consciousness, and the nature of life.

Weirdly, most of the religious folks think we can leapfrog over such things with God, which is indistinguishable from hallucination. Weirdly, most of the scientific folks also think we can leapfrog over such things by relying on our senses and logic, but there can never be a (final) Grand Unified Theory of anything.

We need to regain the humility that the Enlightenment brought us, with (among other things) its democracy, public evolution of science, and adversarial justice.
