Your piece grounds existentialism in evolutionary biology in a comprehensive and for me unprecedented way. Actually this amazing piece is bigger in scope – consciousness, intra/extraversion, etc – half the piece felt worth highlighting -- just that the “bio-existentialism” was for me the centerpiece. After reading this over a dreary morning coffee, I became literally thrilled by so many great ideas communicated so well. I wish I could write at your level.

If you’ll forgive the sidebar, you’ve expressed the bio-existentialist foundation of truth units. Beyond animal qualia, humans use their qualia to create a world beyond the world – a world of self-consciousness evolving into culture and civilization.

The naïve human burns her hand, the experience is internalized as a truth – “don’t touch hot things.” With more experiences, shared with other humans, the tribe structures these internalizations into more comprehensive truth. Truth becomes a foundation on which to build equitable relations between humans, and to build technological affordances, from agriculture to deep science. As a basic organizing principle, truth is a tool for all human activity – even the activity of staying sane, when you include truth in its poetic artistic sense. Truth only starts to fail us as a tool when it comes to constraining the nature inside us.
