Unknown unknown: Difference between revisions

{{def|Unknown unknown|/ʌnˈnəʊn/|n|}}Something that you don’t know that you don’t know, as famously articulated by [[Donald Rumsfeld]]. This, of course, presents an immediate {{t|paradox}}, because if you ''know'' that you don’t know that you don’t know something — which for you to be talking about unknown unknowns, you must, then this is a [[Known unknown|''known'' unknown unknown]], which I rather think — but to be clear, I don’t ''know'', as such — must be a variety of [[known unknown|''known'' unknown]]. Which makes it an ''unknown'' known unknown unknown. Since I do ''know'' that I am not sure about this I can confidently, and with some relief, rest my case at a known unknown known unknown unknown.
