(fs : I just got the Tractatus again and am slowly going through it, but I listened to a podcast https://www.bbc.co.uk/programmes/p0054945. and learned I was reading it all wrong. You need to follow individual points through, like 1.1, 1.2, 1.3 and then 1.1.1, 1.1.2, 1.1.3, basically do a breadth first reading, not a depth first reading.)
