I'm explaining the theme in detail because you didn't understand it. I did, of course, because I'm a world-class genius. I figured out the theme from just looking at the empty grid. In fact, I saw "The Matrix"-like patterns of flowing green characters throughout the encoded .puz file even before opening it. Heck, I even predicted the concept before Evan came up with it.
(Okay, fine, Jim Horne explained it to me.)
Each of the four themers is a common (more accurately, "common") logical fallacy, treated literally. Here I was, thinking that the SLIPPERY SLOPE is just the big pile of dirt in my backyard where my kids have been digging for dinosaur bones, and it's a classical logical fallacy.
What, you don't know exactly what a classical logical fallacy is? Sigh, I'll deign to explain it to you, I suppose.
(Jim. Psst. What exactly is a classical logical fallacy again? Why is a SLIPPERY SLOPE considered to be one?)
Jim explained it all to me, but honestly, I stopped listening after about three words. So just nod your head like I did and tell people, of course, the SLIPPERY SLOPE is a logical fallacy, dummy.
Pro tip: if you yell it super loud, you'll sound even more convincing.
I enjoyed the bonuses, THE RAVEN and BLAST OFF delightful. THE RAVEN crossing POTOMAC is even better, a bit of a shout-out to Poe's home town of Baltimore. Toss in some BIRD FLU, RWANDA / PRAGUE, and that's a lot to enjoy.
The short fill was mostly fine, although there is a real-life logical fallacy: ORONO crossing MOA doesn't seem fair. I don't think—
Huh? That's not a logical fallacy, you say?
YOU'RE A LOGICAL FALLACY.
All in all, a curious theme that Jim got immediately and appreciated because of his more cultured background, and one that I completely and totally didn't miss whatsoever.
