As Bryan Brey stated already.
The First principle is continuous recursive evolutionary computation of the defeat of entropy(release of pressure) by organization, using accumulation, vibration, and spin, producing persistence in the form of that thing we call mass. All existence evolves from this one single cause.
From this first principle we discover the ternary logic of evolutionary computation and the hierarchy of ternary logics that describe all existential phenomena in the universe.
It really is that simple.
You can memorize about twenty general rules of ternary logic and explain all of existence.
Understanding grammar (speech) which also consists of continuous recursive disambiguation of experience into unambiguous references sufficient for transfer of meaning, is a bit harder, but we can teach the basics rather quickly.
Yes it is that simple.
Any behavior you can refer to is explicable by a hierarchy of causality using the hierarchy of first principles, all of which are mere applications of the single first principle.
