We Americans like to shorten things. A lot. We abbreviate, we create acronyms, we put together sets of initials and call them acronyms, we use codes and invent shorthand for longer expressions. It’s just what we do—saving time for more important things, like Twitter or watching cat videos on YouTube. But sometimes the real meaning of a phrase gets lost in all that shrinking and trimming.
Here’s the real story behind tasteless pudding and edgeless envelopes.
Tasteless Pudding: The original phrase is, “The proof of the pudding is in the taste.” Sometimes, it’s expressed as, “the proof of the pudding is in the eating.” There, now, that wasn’t so long or difficult, was it? And, wow, this way it makes sense because what could “the proof is in the pudding” possibly mean? Most folks would interpret it to mean that “the quality, effectiveness or truth of something can only be judged by putting it into action or to its intended use,” but that’s a stretch.
Back in the 14th century, of course, a pudding would have been a savory dish, not a sweet dessert, and more like a sausage (or a haggis) than @JELLO Instant Chocolate Fudge in a box. A recipe for such a medieval pudding would call for the stomach or entrails or an animal (pig, sheep, etc.) washed clean and stuffed with a mixture of minced meat, fat (usually suet), oatmeal and seasonings, then tied off at the ends and boiled. That makes it even more important for the pudding to taste good. Who wants to eat an insipid sausage? Or a bland haggis?
Edgeless Envelope: Another, more recent phrase that gets shortened into meaningless gibberish is, “Pushing the envelope.” Again, what does this mean? Who would push an envelope? What for? How far do you push it? What happens if you don’t push the envelope far enough?
Well, the original phrase is, “Pushing the edge of the envelope.” I have seen some definitions that try to make sense of the shortened version in the context of letters but, really, how ridiculous is that? Even Sisyphus pushed a rock, not an envelope.
This phrase comes originally from @NASA and the space program and was popularized by Tom Wolfe in his novel, The Right Stuff. In aeronautics, the envelope is, “the outer boundary of all the curves that describe the performance of the aircraft under various conditions of engine thrust, speed, altitude, atmospheric conditions, and the like.”
It generally refers the known limits for the safe performance of the aircraft, which get dicier the higher it goes. But pushing those limits is what test pilots are paid to do. When I first encountered this phrase in @aviationweek magazine (where I was placing ads for my company) it referred to the space plane, which could fly to utmost limits of the atmosphere, where it touches space.
Doesn’t that make more sense? Isn’t it a better metaphor? Doesn’t it feel, well, edgier?
