Graduate courses in philosophy at a top-tier department was where I learned it, lol. If you're interested, I can't recommend Cora Diamond's and James Conant's works on Wittgenstein enough (and "the resolute reading" in general). And would also strongly suggest not listening too closely to any modern author who thinks Russel understood Wittgenstein at any point (Wittgenstein certainly _never_ thought so).
