As biologically and culturally evolved beings, humans seem to have certain epistemological proclivities. Perhaps asking "why questions" is one of these proclivities. Perhaps sometimes asking "why questions" is nonsensical. Tantamount to asking for a square circle.
I was thinking about infinite regression of explanations. People always end up asking why instead of how. What makes us think there is a why? The human search for meaning? Perhaps there is ultimately none. This might be the case even if it is unsatisfactory.
The search continues.
