    Wrong title. The linked piece is called "What the Tortoise should have said to Achilles." In this case in particular, this makes a huge difference.

      Actually, the piece is called "What Achilles should have said to the Tortoise" still a big difference though.

      The actual "original" by Lewis Carrol:

      "What the Tortoise Said to Achilles," Mind 4, No. 14 (April 1895): 278-280

      is available online, and should be read before the linked article:

        In other words: you can hand someone a proof, but you can't force them to read it. If the tortoise is unwilling to tell you what exactly a proof must entail, then he's effectively not interested in being a rational agent who is compelled to agree to facts logically derived from premises.

          The logical conclusion of this is Achilles inventing tortoise soup.
