..in an absolute way. We still can relative to other
beliefs. And that isn;t a problem specific to higher-level
categories such as reason and logic. The Trilemma applies
just as much to microphysical causality

Then the sense in which we are not robots is somewhat honorific:
we are not because we have consciousness, but consc. doesn't
explain out behaviour since it doesn't cause anything , so we behave

The claim is more that it causes. And it could be causal under
interactive dualism (brain causes consc causes different brains state)
and it could be causal under mind brain identity: mind is identical
to brain; brain causes; therefore mind identically causes.

Again, the trillema only means there is no non-arbitrary ultimate
The trillema does not mean that nothing whatsoever is caused.
In any case it is a rather poor reason for dismissing the causal
efficacy of consciousness. You are saing that you are not causally
responsible for what you have written here, for instance

If true knowledge is unobtainable, it makes a lot
of sense to settle for useful knowledge.

Yep. That it is in a sense caused by evolution does not make it wrong.
