T-Rex: Suppose I theorized that "all ravens are black"! Doing so is logically equivalent to hypothesizing "if something is not black, then it is not a raven."
T-Rex: Contraposition, baby!
T-Rex: So far we're in Normal Land, but stay with me. Now, if I then SAW a black raven, then that'd be some nice evidence that supports my "all ravens are black" hypothesis.
T-Rex: NOW, let's suppose I see Sonic - famously a blue hedgehog that runs fast - and I, entirely accurately, think "this blue hedgehog is NOT black, and what's more, it is NOT a raven".
Utahraptor: Seems normal to me!
T-Rex: IS IT THOUGH??
T-Rex: Sure, a black raven supports my "all ravens are black" theory. And a blue hedgehog is equally evidence for my "if something is not black, then it's not a raven" hypothesis. GREAT. But remember, that hypothesis is LOGICALLY EQUIVALENT to "all ravens are black"!
Utahraptor: So?
T-Rex: So we've LOGICALLY PROVEN that seeing SONIC D. HEDGEHOG is somehow evidence for all ravens being black!! BUT THAT'S NUTS! We're in CRAZY LAND now, and we all just have to live with this unsolved problem in logic!!
Off panel: Frig, my sanity!!
T-Rex: FRIG, MINE TOO!
