Okay. It's not that exciting. It may not even be challenging. It's certainly not strenuous. But the point is that it's supposed to distract you, my beloved readers, from my lack of effort today. Please ignore the previous sentence.
So here it is, something to flex your brain over: a philosophical feat too lofty for Voltaire, too enigmatic for Descartes, too circular for Socrates. You could probably encounter it as a warm-up exercise in a creative writing class:
"Describe the flavor of salt."
That's it. Go. Assume you're describing salt to someone who's never tasted it before (heathens), so that you can't just say, "It tastes salty" (Mmmm, how succinct)...
Perhaps at some point, if I'm feeling particularly cerebral, I'll revisit the topic from a philosophical perspective. "What are the consequences of asking such a question? Do we acknowledge the limitations of language as a communicative form?" OH, THE SUPERCILIOUSNESS.
