An extraordinary educator and teacher. In the book I read, he discusses how to raise young people who are open to criticism and to offering criticism, as well as the propagandistic education prevalent in the West and how to overcome it. He is not a Marxist-Leninist, but rather closer to democratic socialism; however, his writings on epistemic curiosity, teaching and learning, and solidarity are refreshing and contain insights from which socialists too, have much to learn.
The fact that evangelical lobbies in the West have also banned his writings and are trying to ban it further proves that the education of the people in Latin America is being stifled.
I'm still reading Neuromancer and started Boris Hessen's The Social and Economic Roots of Newton's Principia.
