How Hirsch uses it

Every occurrence, grouped by book and chapter, with the claim it was linked to support and (where the extraction regenerated one) the underlying warrant.

2006 · The Knowledge Deficit
Scholarly debate regarding whether alphabetic writing was invented only once in human history.
direct Alphabetic reading and writing are inherently unnatural for the human organism.
ch 1 · expert_testimony · kd:ch1_E13
Warrant (implicit): The difficulty and historical singularity of an invention indicate that it lacks a basis in universal human biological architecture.
could fail ifThe 'single invention' theory of the alphabet is a contested historical hypothesis; multiple independent inventions would suggest a more 'natural' affordance.
The historical failure of humans to develop or learn the alphabet code without explicit intervention until the Phoenicians.
direct Humans do not possess a built-in alphabet-phoneme-mapping faculty, but they do possess a built-in word-meaning-learning faculty.
ch 3 · historical_example · kd:ch3_E23
Warrant (implicit): The absence of a cultural technology across most of human history indicates the lack of an innate biological module for that specific technology.
could fail ifCultural evolution often requires a specific threshold of material conditions or social stability to manifest, regardless of underlying biological readiness.
The historical development of the alphabet as a late, artificial invention of civilization rather than a biological evolution.
direct Alphabetic decoding is an artificial product of civilization rather than a natural biological faculty.
ch appendix · historical_example · kd:chappendix_E13
Warrant (explicit): Human skills that were developed recently in evolutionary history cannot be acquired through the same 'natural' or 'effortless' mechanisms as biological adaptations.
could fail ifThe brain's neuroplasticity allows it to repurpose biological circuits (like the visual word form area) to make 'artificial' skills feel functionally innate.
