Can I get a summary on Wittgenstein? He rarely gets the amount of attention as other 20th century philosophers, but he's still regarded as the most important one. I feel like there's a dearth of understanding him in the popular sphere.
If you want something more than the Wikipedia content, try the book Wittgenstein's Poker. My book club read it about a decade ago and it's one of the few titles we keep referring back to.
