Nudge: What must the wise know beforehand?

I read this in some recent research: “The wise man must not know after but know before.” —Epicharmus (460 BC), cited in C. Spicq, TLNT, 2:472

I used it on my blog, also, but here’s a question for you to answer in the comments or, if you’re a long-winded Fellow (which is a good thing), in a separate TFR post: What must the wise man know beforehand?

Yup, I made a Nudge out of it.
