Brilliance is here. Brilliance has come in person. Here is philosophy, in person. Here is logic - because that is the supposed theme of Wittgenstein Jr's lectures: logic. Logic is here, to sort everything out. Logic, in person, to answer every question of philosophy. 

Logic! It's wasted on us. Logic! He speaks over our heads - very far over our heads. Logic, logic. What does he mean by this word? What do we understand by it? Nothing, apparently. Nothing at all.

Doyle bought Smith's Introduction to Logic, Chakrabarti, Goodchild's Logical Puzzles. I bought, Logic: An Idiot's Guide, and Whitmarsh, Logic in Sixty Minutes. Scroggins found an old edition of Copi's book on logic - much more difficult than anything published today, and Guthrie ordered a book on Fitch style proofs. But none of these books has anything to do with what Wittgenstein Jr calls logic.
