PewDiePie mentioned The Discourses of Epictetus by Epictetus 5 times

Another book I've talked about so much we're going to read Epictetus Discourses and Selected Writings. If you for some reason haven't read this with the amount of yapping I've done about this book you got to do it now! I think if I had to pick one book out of all of these, one book to rule them all, I would pick The Enchiridion.

People always ask me "oh I want to read philosophy where should I start?" I would highly recommend Epictetus, specifically not this one, the Enchiridion, this one just has it contained.

On Felix's bookshelf.

We read Epictetus Discourses and selected writings. Did you love it did you hate it? What would you rate it? [...] I picked this book because it's fairly simple, it's straightforward and it's a good introduction to stoic philosophy. There's probably better examples but this is what I chose. I really really like this book
