      I preferred the Facebook group “If 2,147,483,648 people join this group, then an integer overflow may occur” back in the day.

      Drag likes the punchline here, but the setup doesn’t make sense

      “So you’re saying I should get a licence so I can drive a car, and I can drive a car because I have a licence?”

      Having a qualification isn’t tautological just because it can be phrased in two different ways

        (a <=> b) <=/=> [(b => TRUE) <=> a]

        This is a critique of honor societies which do not serve a point in proving someone’s “honor”. The college requirement is essentially: Join this club to prove you have joined this club. Anyone can join an “honor” society without demonstrating anything related to honor, meaning:

        ([Joining an honor society] => TRUE) <=> [Being allowed to join college]

        Being allowed to drive a car implies having a license and having a license implies being allowed to drive a car. Neither of these implies TRUE - in an ideal world at least.

        By the way, TRUE is a tautology because it is always true, which is the definition of a tautology. Unnecessary repetition is not a requirement of a tautology.
