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?
Pluralist school 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. The school consisted of Anaxagoras, Archelaus, and Empedocles. It can also be said to have included the Atomists, Leucippus and Democritus. The Pluralists rejected the idea that the diversity of nature can be reduced to a single principle (monism). Anaxagoras posited that nature contained an innumerable number of principles, while Empedocles reduced nature to four elements (fire, air, earth, and water) which could not be reduced to one another and which would be sufficient to explain change and diversity.
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.
