Parry’s logic of Analytic Implication
and Relevance logic are two sensible systems
that get rid of the Principle of Explosion.

It was dead-obviously correct to anyone paying
any attention at all that every contradiction
only semantically entails FALSE.

The only reason that it took more than five minutes
for everyone to agree to this is that logicians are
a herd of sheep and mindlessly obey what they have
been taught even if this means that they must jump
off a cliff.

My 28 year goal has been to make
"true on the basis of meaning expressed in language"
reliably computable for the entire body of knowledge.
The complete structure of this system is now defined.

The entire body of knowledge expressed in language is
comprised of two types of relations between finite strings:
(a) *Axioms* Expressions of language that are stipulated to be true.

My system bridges the analytic/synthetic distinction by
expressly encoding all empirical "atomic facts" in a formal
language such as CycL of the Cyc project.

(b) *Inference Rules* Expressions of language that are semantically
entailed syntactically from (a) and/or (b).
