idea (ιδεα)
(Language: Greek)
Short Description: the visual aspect of anything
Long Description: in non-technical use the term refers to the visual aspect of anything; for Plato and Platonists, it is the highest noetic entity, the eternal unchanging Form, the archetype of the manifested material thing; in Plato, idea is a synonim of eidos, but in Neoplatonism these two terms have a slightly different meaning.
