Science is so powerful that it drags us kicking and screaming towards the truth despite our best efforts to avoid it.

There's no such things as survival of the fittest. Survival of the most adequate, maybe. It doesn't matter whether a solution's optimal. All that matters is whether it beats the alternative.

Perfect hexagonal tubes in a packed array. Bees are hard-wired to lay them down, but how does an insect know enough geometry to lay down a precise hexagon? It doesn't. It's programmed to chew up wax and spit it out while turning on its axis, and that generates a circle. Put a bunch of bees on the same surface, chewing side-by-side, and the circles abut against each other - deform each other into hexagons, which just happen to be more efficient for close packing anyway.

Humans didn't really fight over skin tone or ideology; those were just handy cues for kin-selection purposes. Ultimately it always came down to bloodlines and limited resources.

What's the difference between being dead, and just not knowing you're alive?

Brains are survival engines, not truth detectors.

Computers bootstrap their own offspring, grow so wise and incomprehensible that their communiqués assume the hallmarks of dementia: unfocused and irrelevant to the barely-intelligent creatures left behind. And when your surpassing creations find the answers you asked for, you can't understand their analysis and you can't verify their answers. You have to take their word on faith.
