If I may be a bit technical: ZOW!

While I have some knowledge of philosophy, some of this is certainly beyond my ken. Still, as a simple minded biologist that had to examine phislophy for answers I wanted, maybe I can offer you a thought.

"rather than political, historical, or linguistic bias — is a bedrock of knowledge." What if one other part is missing?

"The only viable answer in the modern world is that we’re primates that haven’t entirely escaped our animal nature." ... So what is that nature? I recently wrote an essay for Medium that I think you might find relevant. I was looking at why there is population decline and basically concluded that the exclusive teaching of science is not offering what is required to release (in Conrad Lorenz's terms) our moral instincts, including the instinct to have a family. The proposed solution is to teach the very basics of philosophy at a very young age (as it used to be taught). In ways, that discussion might illuminate something about our "animal nature" and perceptions. May I recommend a glance at it...
