No. sentence
1 The Greek words oida (οἶδα, "(I) know") and eidos (εἶδος, "species"), a thing seen, have the same root as the word idea (ἰδέα), a thing ἰδείν to see.
2 The word idea comes from Greek ἰδέα idea "form, pattern," from the root of ἰδεῖν idein, "to see."
3 Plato in Ancient Greece was one of the earliest philosophers to provide a detailed discussion of ideas and of the thinking process (in Plato's Greek the word idea carries a rather different sense from our modern English term).
4 He was particularly indignant against the almost universal use of the word idea in the sense of notion or opinion, when it is clear that idea can only signify something of which an image can be formed in the mind.
