Atom-and-void physics is taught under Democritus' name as later sources report a fifth-century Abderite doctrine
Received Abderite teaching holds that what is are atoms and void. Democritus’s documented role is: Later physics reports atoms and void as his (and Leucippus') teaching. 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.

Received Abderite teaching holds that what is are atoms and void. Democritus’s documented role is: Later physics reports atoms and void as his (and Leucippus') teaching. He did not typeset Diels. Medium confidence on unique wording. Later editors, printers, and excavators remain named where they appear. Democritus's documented role is: Later physics reports atoms and void as his (and Leucippus') teaching. He did not typeset Diels. Medium confidence on unique wording.
Context
Abdera is the received city. Leucippus is a joint or prior name in the same heading. Named others on the file: Leucippus as co-heading; Aristotle as later hostile witness. The public setting is the file around -0430-01-01. The instrument stays Atom-and-void physics is taught under Democritus' name as later sources report a fifth-century Abderite doctrine. The setting of Atom-and-void physics is taught under Democritus' name as later sources report a fifth-century Abderite doctrine is the public file around -0430-01-01. Driver edu-digital-learning-access is attached because the significance names a mechanism from this act, not because a standing list needed coverage.
Confidence is stated on the impact path, not hidden in adjectives. Mixed effects of Atom-and-void physics is taught under Democritus' name as later sources report a fifth-century Abderite doctrine are separate paths.
Why it matters
Naturalist physics as public teaching, not a laboratory notebook. Welfare reading improving. The attached mechanism is A public natural-philosophy doctrine is an education path of medium confidence because the books are lost. 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.
That reading is an impact-path choice, not a property stored on the Fact itself.

What the sources establish
SEP and Britannica independently treat atomism as a received Democritean doctrine known through later reports. Official: Stanford Encyclopedia of Philosophy — Democritus (https://plato.stanford.edu/entries/democritus/ (opens in a new tab); Stanford Encyclopedia of Philosophy). Independent: Britannica — Democritus (https://www.britannica.com/biography/Democritus (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.

No autograph On Nature. Conventional fifth-century dating is handbook chronology. Established: a sourced public record of Atom-and-void physics is taught under Democritus' name as later sources report a fifth-century Abderite doctrine under -0430-01-01.
Shared responsibility is part of Atom-and-void physics is taught under Democritus' name as later sources report a fifth-century Abderite doctrine. Naming Democritus does not delete co-authors, institutions, or later transmitters. The lag from -0430-01-01 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.
If a number is not in the two records named above, it is not supplied here.
Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.
