Don't bother, it's just the usual nonsense by Wittgenstein, this time related to the rule following discussion. Wittgenstein has not published anything of substance and is the most persistently overrated philosopher of 20th Century. Thanks to his obscurity and an ability to invent interesting puzzles, which he scribbled on little notes, he has gathered a large number of fanatic followers. Ironically, if Wittgenstein was still alive, he'd make relentless fun of most of these followers.
He was good at pointing out problems. The rest of his work consisted of hand-waving.
