The Great World-System (Megas Diakosmos)
Democritus's c. 430 BCE lost work — atomist cosmology preserved through Aristotle, Theophrastus, and the doxographic tradition
Tradition: Greek atomism / Pre-Socratic natural philosophy
Democritus's c. 430 BCE lost cosmological masterwork — foundation of Greek atomism
The Great World-System (Megas Diakosmos, c. 430 BCE) was the principal cosmological work of Democritus of Abdera, the foundational figure of Greek atomism (with his teacher Leucippus). The work treated the fundamental atomist doctrine — atoms (atoma) and void (kenon) as the sole real constituents — and developed from it a comprehensive cosmology covering the formation of worlds, planetary motions, sensible qualities, the soul, and the proper conduct of life. The text is lost; reconstructed from citations and paraphrases in Aristotle, Theophrastus, Sextus Empiricus, Diogenes Laertius, and the doxographic tradition.

School Embodiments
Founding text of the Greek atomist tradition — paradigm statement of atomist cosmology.
"Atoms and void; everything else is convention." (Democritus, summary doctrine preserved via Diogenes Laertius IX.44)
Strong naturalist-philosophical commitment — natural-mechanical explanation of all phenomena including life and mind.
"All things happen by necessity; the seeming randomness is the disguise of necessity that we have not yet penetrated." (Democritus, fragment)
Major pre-Socratic philosophical text — culmination of the natural-philosophical tradition that begins with Thales.
"The Great World-System is the most ambitious and systematic of the pre-Socratic natural-philosophical works." (Standard scholarly account)
Foundational text for the modern analytic-metaphysical work on substance, identity, individuation.
"What modern analytic metaphysics has learned about mereology, identity, and material composition stands in deep continuity with the Democritean atomist tradition." (Standard modern scholarly account)
Major source for Epicurus and Lucretius — Hellenistic atomism inherited and modified Democritean cosmology.
"Epicurus's cosmology — preserved in Lucretius's De Rerum Natura — is the direct inheritance of the Democritean Great World-System." (Standard scholarly account)
Pluralist-cosmological framework — infinitely many worlds in the infinite void.
"There are infinite worlds; each comes-to-be in its own kosmos out of the infinite atoms and void." (Democritus, fragment via Hippolytus)
Internal Tensions
The work is lost; reconstruction relies on hostile-Platonist witnesses, friendly-Aristotelian witnesses, and the doxographic tradition. Modern atomic-physical theory has substantially vindicated the foundational atomist intuition; the philosophical details remain contested.
