Reddit reviews Pedagogy of the Oppressed: 50th Anniversary Edition

I'm gonna take the long shot here and recommend Paulo Freire - Pedagogy of the Oppressed. It's the type of book that'd slip pass prison restriction (assuming you from US), but also equally powerful and can profoundly impact and influence your nephew's ideology. Pedagogy Of The Oppressed educates one how to think for themselves, and not thinking like other. It's an extremely powerful book that few leftists talk about it. I recommend it.

Also The Wretched Of The Earth by Franz Fanon is another great book I'd recommend.
