[How did speech-alone talk potentiate unconstrained complexity?

Consider the word “property”.

Property is not a thing. One cannot see, hear, touch, taste or smell the referent. The referent cannot be pictured or pointed to.

The purely symbolic word ‘property’ did not exist in hand-speech talk. Its referent cannot be imaged or indexed.

Speech-alone talk can label anything, even non-sensual things like “property”.

Real things and patterns no longer receive iconic and indexal words. Instead, we project iconic and indexal qualities into words that label things that we figure must be real, like the word “property”.]
