The use of εἶδος and ἰδέα in the presocratic philosophy

Abstract

In this article I analyse, from a semantic standpoint, the terms εἶδος and ἰδέα in the Presocratic philosophers. Based on the context in which the terms appear, I quote every fragment in full, so that the terms can be understood. On top of the fragment, in bold, I write the word, whether a verb, adjective, numeral or noun, on which εἶδος or ἰδέα depends. When the terms εἶδος or ἰδέα do not refer to any particular word, the quote is not preceded by a heading.
