The number of kinds of knowns and unknowns, like all binaries, increases twofold per level of <a href="https://en.wikipedia.org/wiki/Metaknowledge">meta-knowledge</a> (knowledge about your knowledge). If you are at all familiar with <a href="https://en.wikipedia.org/wiki/Bit">bits</a> (binary digits) then this idea should hopefully click right away. In this piece I&rsquo;ll explore in detail the meaning of knowns and unknowns at the first and second levels of meta-knowledge. Then I&rsquo;ll try to convince you that from the third level onwards, there is no useful distinction from the second level.</p>https://blog.peter-l.in/about/Tue, 09 Jun 2026 00:00:00 +0000https://blog.peter-l.in/about/<p>Hello!
