[58] The word Idola is manifestly borrowed from Plato. It is used twice in connexion with the Platonic Ideas (N. O. i. 23, 124) and is contrasted with them as the false appearance. The εἴδολον with Plato is the fleeting, transient image of the real thing, and the passage evidently referred to by Bacon is that in the Rep. vii. 516 A, καὶ πρῶτον μὲν τὰς σκιὰς ἂν ῥᾷστα καθορῴη, καὶ μετὰ τοῦτο ἐν τοῖς ὕδασι τά τε τῶν ἀνθρώπων καὶ τὰ τῶν ἄλλων εἴδωλα, ὕστερον δὲ αὐτά. It is explained well in the Advancement, bk. i. (Works, iii. 287). (For valuable notes on the Idola, see T. Fowler's Nov. Org. i. 38 notes; especially for a comparison of the Idola with Roger Bacon's Offendicula.)

[63] This better known in the order of nature is nowhere satisfactorily explained by Bacon. Like his classification of causes, and in some degree his notion of form itself, it comes from Aristotle. See An. Post. 71 b 33; Topic, 141 b 5; Eth. Nic. 1095 a 30. It should be observed that many writers maintain that the phrase should be notiora natura; others, notiora naturae. See Fowler's N. O. p. 199 note.
