Leucippus
Leucippus (/luːˈsɪpəs/; Greek: Λεύκιππος, Leúkippos; fl. 5th century BCE) is a pre-Socratic Greek philosopher who has been credited as the first philosopher to develop a theory of atomism.

Leucippus' reputation, even in antiquity, was obscured by the reputation of his much more famous pupil, Democritus, who is also credited with the first development of atomic theory. Few details about Leucippus' life are known, and even his historical existence has on occasion been questioned.
Biography
Leucippus's dates are not recorded and he is often mentioned in conjunction with his more well-known pupil Democritus. Although Diogenes Laertius[1] lists possible birthplaces as Miletus, Abdera and Elea, historians do not consider this testimony reliable. Some sources claim that around 440 or 430 BCE Leucippus founded a school at Abdera, with which his pupil, Democritus, was closely associated.[2] There is mention that a Leucippus founded the city of Metapontum, which honored this Leucippus with a coin.
Philosophical views
"Nothing happens at random, but everything from reason and by necessity.[3]"
— Leucippus,On Mind[4]
Leucippus is typically associated with atomism—the idea that everything is composed entirely of various imperishable, indivisible elements called atoms. It is difficult to determine which contributions to atomism come from Democritus and which come from Leucippus. Aristotle and his student Theophrastus explicitly credit Leucippus with the invention of atomism. In Aristotelian terms, Leucippus agreed with the Eleatic argument that "true being does not admit of vacuum" and there can be no movement in the absence of vacuum. Leucippus contended that since movement exists, there must be empty space. However, he concludes that vacuum is identified with nonbeing, since "nothing" cannot really be. According to Aristotle, Leucippus differed from the Eleatics in not being encumbered by the "conceptual intermingling" of being and non-being, and Plato made the necessary distinction between "grades of being and types of negation".
Writings
According to Theophrastus, Leucippus was the author of a work called The Great World System that was otherwise typically attributed to Democritus,[5] which has not survived. A single quotation survives from another work attributed to him called On Mind.[6]
Legacy
A brief notice in Diogenes Laërtius’s life of Epicurus says that on the testimony of Epicurus, Leucippus never existed. As the philosophical heir of Democritus, Epicurus's word has some weight, and indeed a controversy over this matter raged in German scholarship for many years at the close of the 19th century. Furthermore, in his Corpus Democriteum,[7] Thrasyllus of Alexandria, an astrologer and writer living under the emperor Tiberius (14–37 CE), compiled a list of writings on atomism that he attributed to Democritus to the exclusion of Leucippus. The present consensus among the world's historians of philosophy is that this Leucippus is historical.
Fragments and doxographical reports about Leucippus were collected by Hermann Diels (1848–1922), firstly in Doxographi Graeci (Berlin, 1879, reprint Berlin: de Gruyter, 1929) and then in Die Fragmente der Vorsokratiker, Berlin, 1903, 6th ed., rev. by Walther Kranz (Berlin: Weidmann, 1952; the editions after the 6th are mainly reprints with little or no change.) Diels was the leading proponent for a historical Leucippus.
