I saw in a thread, but I can not remember which, a discussion about the meaning of Logos.
This is my contribution to it.
"This article is about Logos (plural: logoi) in philosophy, rhetoric, linguistics, psychology and theology. For the plural logo, see Logo. For other uses, see Logos (disambiguation).
Logos, Greek spelling
Logos ( /ˈloʊɡɒs/, UK /ˈlɒɡɒs/, or US /ˈloʊɡoʊs/; Greek: λόγος logos) is an important term in philosophy, psychology, rhetoric and religion. Originally a word meaning "a ground", "a plea", "an opinion", "an expectation", "word," "speech," "account," "reason,"[1][2] it became a technical term in philosophy, beginning with Heraclitus (ca. 535–475 BC), who used the term for a principle of order and knowledge.[3]"
