Let’s abstract.
What is True?
a) True is a word
b) It has four letters
c) It’s formed by a certain motion of our tongue and vocal chords and if you have had hearing in your life, you subvocalize the word when you read it, albeit very quickly.
What else is True?
It’s something that is straight, flat, even.
True is also honest. Just. Consistent. Narrow. Strict. Rightful. It comes from a word meaning faithful, which comes from a word meaning Tree.
It has synonyms: bona-fide, certifiable, authentic… these are just a few things that come to mind.
All of these things come together when we consider True.
But True is better defined by its antonyms [these I looked up]:
bogus, counterfeit, fake, false, mock, phony (also phoney), pseudo, sham, spurious, suppositious, supposititious, unauthentic, unreal.
All of these things come into play when considering “true” and “false”.
