PREFACE
Anthropology and neuroscience prove logicians wrong when they claim Aristotelian logic is universal
They show that Aristotelian logic is not a universal feature of the human mind, but a culturally specific cognitive style produced by particular neural, linguistic, and social conditions.
This reframes the status of Aristotelian logic, not its internal correctness.
But
The dean paradox
For a logician, this is like telling a Euclidean geometer that straight lines do not exist anywhere in the universe.
It is not a correction — it is a collapse
But Dean does not replace classical logic with a new system.

He shows:
• no system can be universal
• no logic can describe reality fully
• no creature can step outside its perceptual filter
• truth is hardware relative
• identity is not fundamental
• the continuum is a fiction
This is not a paradigm shift. It is a paradigm termination.
