River fragments print a flux teaching under Heraclitus’s name
River fragments under Heraclitus’s name teach that one cannot step twice into the same river. Heraclitus’s documented role is: Later authors quote river-and-flux sayings as Heraclitean. In the causal graph this event strengthens Digital Learning Access, a driver that weakens Learning Poverty Rate (low- and middle-income countries) — an improving welfare path.

River fragments under Heraclitus’s name teach that one cannot step twice into the same river. Heraclitus’s documented role is: Later authors quote river-and-flux sayings as Heraclitean. He did not leave an autograph book; later Diels-Kranz is not -500 type. Flux is a distinct saying-cluster, still on later carriers. Later editors, printers, and excavators remain named where they appear.
Context
Later quoters, unnamed rhapsodes of sayings, and a missing book already sit in the file. A river-saying is not unique authorship of every later process-philosophy. Later SEP is access, not his act. Named others on the file: Later quoting authors, DK editors as access, and neighbouring Eleatic opponents in later doxography share the cluster. The public setting is the file around -0500-04-01. The instrument stays River fragments print a flux teaching under Heraclitus’s name. The setting of River fragments print a flux teaching under Heraclitus’s name is the public file around -0500-04-01. Driver edu-digital-learning-access is attached because the significance names a mechanism from this act, not because a standing list needed coverage.
That reading is an impact-path choice, not a property stored on the Fact itself.
Why it matters
Medium confidence on unique wording. Welfare reading improving. The attached mechanism is A dated fragment-cluster put a public change-teaching into later philosophy, distinct from the war-fragment and from the no-autograph gap. Lag to any modern indicator is not treated as zero. This path is attached because the mechanism is named from this act, not because a driver list needed coverage. The welfare reading on this path is improving.
Shared responsibility is part of River fragments print a flux teaching under Heraclitus’s name. Naming Heraclitus does not delete co-authors, institutions, or later transmitters. The lag from -0500-04-01 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.

What the sources establish
SEP and Britannica independently treat flux/river as a distinct Heraclitean fragment-cluster. Official: Stanford Encyclopedia of Philosophy — Heraclitus, flux fragments (https://plato.stanford.edu/entries/heraclitus/ (opens in a new tab); Stanford Encyclopedia of Philosophy). Independent: Britannica — Heraclitus, river fragments (https://www.britannica.com/biography/Heraclitus (opens in a new tab); Encyclopaedia Britannica). The two URLs are different pages. Where the carrier is a later edition or a received narrative, that limit is stated rather than upgraded to an autograph. Official carrier: Stanford Encyclopedia of Philosophy — Heraclitus, flux fragments (https://plato.stanford.edu/entries/heraclitus/ (opens in a new tab); Stanford Encyclopedia of Philosophy). Independent carrier: Britannica — Heraclitus, river fragments (https://www.britannica.com/biography/Heraclitus (opens in a new tab); Encyclopaedia Britannica).
Established: river/flux as a received Heraclitean cluster. Not established: an autograph book of 500 BCE. Established: a sourced public record of River fragments print a flux teaching under Heraclitus’s name under -0500-04-01.
