# Later reports leave Democritus and Leucippus under a joint atomist heading that this catalog does not pretend to unpick

Date: 435

## The fact

The public atomist heading is joint or prior with Leucippus as later printed. [Democritus](/people/democritus)’s documented role is: He is not hereby proved the sole author, nor is Leucippus deleted. The joint file is the instrument. Later editors, printers, and excavators remain named where they appear. Democritus's documented role is: He is not hereby proved the sole author, nor is Leucippus deleted. The joint file is the instrument.

## Context

Fifth-century Ionia/Abdera as received. 1903 DK still prints a joint map; that print is not this Fact's date. Named others on the file: Leucippus; later doxographers. The public setting is the file around -0435-01-01. Unnamed clerks, soldiers, printers, or later editors may appear without becoming this instrument. The instrument stays Later reports leave Democritus and Leucippus under a joint atomist heading that this catalog does not pretend to unpick. The setting of Later reports leave Democritus and Leucippus under a joint atomist heading that this catalog does not pretend to unpick is the public file around -0435-01-01. Shared offices, unnamed crews, printers, or later editors may appear without becoming this instrument. Driver [political-polarization](/drivers/political-polarization) is attached because the significance names a mechanism from this act, not because a standing list needed coverage.

The attached driver is political-polarization. The welfare reading used in this dossier is worsening. That reading is an impact-path choice, not a property stored on the Fact itself.

## Evidence and sources

SEP entries on both names independently flag the separation problem. Official: Stanford Encyclopedia of Philosophy — Leucippus (https://plato.stanford.edu/entries/leucippus/; Stanford Encyclopedia of Philosophy). Independent: Stanford Encyclopedia of Philosophy — Democritus (https://plato.stanford.edu/entries/democritus/; Stanford Encyclopedia of Philosophy). 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 — Leucippus (https://plato.stanford.edu/entries/leucippus/; Stanford Encyclopedia of Philosophy). Independent carrier: Stanford Encyclopedia of Philosophy — Democritus (https://plato.stanford.edu/entries/democritus/; Stanford Encyclopedia of Philosophy).

Identity-file opacity, not a duel. Welfare reading worsening. The attached mechanism is An unseparated co-authorship file is a polarisation-and-opacity path inside the identity of the school. 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 worsening.
