Later lives print communal living as a crowding of the brotherhood
Do write that later lives describe shared tables. In the causal graph this event strengthens Infectious-Disease Transmission, a driver that weakens Life expectancy at birth — a worsening welfare path.
Read the full account
Low-confidence crowding path. He did not write a hygiene tract.
Context
Do write that later lives describe shared tables.
Pythagoras is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.
Why it matters
Printed communal meals are not a modern outbreak table.

Named sage as heading of later school reports. Iamblichus, Euclid’s editors, and later math teachers publish the instrument.
