I always emphasize that there is a evolutionary logic, which  unlike any
other logic, is tautological, that is assume no axioms beyond natural
selection (which is tautological per se)

I will define here this logic as clear as I can.

Therefore evolutionary logic a good foundation for an absolute notion of
both truth (including existence) and morals. Because is-ougth is unified
under this logic.  This logic is rougly speaking convergent with the
classical philosophical-religious logic of common sense. Besides being
materialistic, it debunk the humean nominalist-positivist reductionsisms
and, as i said, return back to the classical philosophical notions.

Really all the modal logics are parts of this evolutionary logic. The
directions of the arrows of the modal logics have a clear evolutionary
background. for example G x -> x, Ox ->x, [] x -> x, Bx -> x, there is a
evolutionary reason behind

What is this evolutionary logic?

Under evolutionary logic, truth, existence and goodness  becomes different
aspects of the same essence, which have different names when seen from the
point of view of logic, epistemology or morals.

The truth of this logic is by definition  equal to
 the-continuation-of-the-mind-in-the-world.
The non sequitur, the definition of false, is the non-continuation-of-the
mind-in-the-world.
Everything that contributes to the continuation of the mind is true, exist
and is good. Everything that does not contribute does not exist, is false
and is evil.

If a notion contributes to the mind dead, this notion is, evidently non
existent (is disappearing or will disappear soon). It is false (non-sequitur).
And it is not good (contributes to the death of the holder and his society)

Therefore It is a fuzzy logic which assign various degrees of truth,
existence and godness depending on the degree, immediacy and clarity with
which something contributes to the persistence of the mind.

There immediate evident, and universally consensuated  concepts that are
truth, exist and are good: For example, that persons are males and females,
the existence of persons, to preserve persons lifes.These sentences are
respectively true, exist and is morally good because the knowledge included
in these statements contribute inmediately and universaly to the
persistence of the human minds in a social environment.

In the other extreme of fuzziness are  more subtle and long term facts that
 does not produce an inmediate persistence of the mind, but are long
term,and in some circumstances  The existence of the electron, the
existence of God, drug prohibition, the platonic realm etc.

The accumulation of knowledge of evolutionary truths happens by many
mechanism: biological darwinism, that develop specific circuirtry to
recognize humans, recognize human faces,  handle social reasoning  (This
instantiates in brain hardware the above statements about persons). There
are also social mechanisms of accumulation of evolutionary knowledge, by
tradition, philosophical, scientific debates, and also violent
confrontation. among peoples and countries. The reason why Lamarkism is not
true is more a factual consequence of the defeat of the USSR than a direct
consequence of scientific debate. It may be said that lisenko Lamarkism was
disastrous because ti contributed to the defeat of the USSR. But had the
USSR won the cold war, we would accept the scientific truth of lamarkism,
since socialism would have been sucessful and lamarkism is the only
coherent evolutionary theory compatible with marxism, and darwinism is not.
It would be far more painful and long term to convince people to get rid of
it .

All these processes are instances of a single process operating at
differente levels: Natural selection. the proces of variation and selection
at the biological, social political etc levels.

Althougn this is formulated in crude materialistic terms,  This is
identical to the classical philosophical and religious logic, that takes
into account the reality of the whole experience of existence of the
mind-soul in the word in all the dimensions: social and individual.   You
may find Biblical and Philosophical texts that assimilate truth, existence
and the good.
