Peirce I think successfully mapped out the concept of the firstness/secondness/thirdness.

The only way you are getting close to expressing firstness is through high speed, unedited word association poetry.

Humans don't really have introspection, we don't have access to what's going on in every subsystem, we don't even have control, otherwise we could think ourselves to death ala breaking emacs with the right line of lisp.

The idea that the thought or intent in your brain survives semantic translation is... well, it can only kinda happen. It can be a target but thinking it's possible in an absolute sense is the old map/terrain mistake.

I think fast iteration with image mocks and wire frame mocks is sufficient, understanding the process of rapid testing with isolated toys before locking in design is the best we can get.
