Does it? Or is it a post hoc explanation? Starting at the most basic level
the rationality so prized by humans is an epiphenomenon, a fairy tale by
triggered neurons to explain what the wetware already did.

Epiphenomena are secondary phenomena occurring alongside or caused by a
primary phenomenon but which have no causal influence of its own on that
primary phenomenon. They're essentially byproducts or side effects.

The assertion that physics and math exist 'outside of humans' is a
long-standing debate (Platonism vs. nominalism, for example).

However, if our rationality is just an epiphenomenon, how can we be
confident in our perception of any external truths?
