"The fact that something is written down is persuasive to people not used to asking questions like: ‘Who wrote it, and when?’ ‘How did they know what to write?’ ‘Did they, in their time really mean what we, in our time, understand them to be saying?’ ‘Were they unbiased observers, or did they have an agenda that coloured their writing?’. (p. 118 of the Black Swan paperback edition of 2007)"
