The Pluralist school was a school of pre-Socratic philosophers who attempted to reconcile Parmenides' rejection of change with the apparently changing world of sense experience, it can also be said to have included which philosopher who was the earliest Greek to develop the theory of atomism—the idea that everything is composed entirely of various imperishable, indivisible elements called atoms. Leucippus often appears as the master to his pupil Democritus, a philosopher also touted as the originator of the atomic theory?
Leucippus Leucippus ( ; Greek: Λεύκιππος , "Leúkippos"; fl. 5th cent. BCE) is reported in some ancient sources to have been a philosopher who was the earliest Greek to develop the theory of atomism—the idea that everything is composed entirely of various imperishable, indivisible elements called atoms. Leucippus often appears as the master to his pupil Democritus, a philosopher also touted as the originator of the atomic theory. However, a brief notice in Diogenes Laertius’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", 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. The matter must remain moot unless more information is forthcoming from the record.
Meta-discussion The term meta-discussion means a discussion whose subject is a discussion. Meta-discussion explores such issues as the style of a discussion, its participants, the setting in which the discussion occurs, and the relationship of the discussion to other discussions on the same or different topics. It is one of many terms based on the inferred meaning of the "meta-" prefix. The etymology for the prefix dates back to use of "Metaphysics" as the title of the treatise by Aristotle that came after his works on physics in the traditional ordering of his books. The fundamental meaning of the prefix in Greek is simply "after." The modern, inferred meaning of a higher-order, self-referential consideration of the nature of an activity—rather than actual, first-level participation in the activity—has led to many neologisms such as meta-wiki.
