I got “Revolution in the Revolution” at the used bookstore, and thought this excerpt in the first section was very interesting:

"Fidel once blamed certain failures of the guerillas on a purely intellectual attitude toward war. The reason is understandable: aside from his physical weakness and lack of adjustment to rural life, the intellectual will try to grasp the present through preconceived ideological constructs and live it through books. He will be less able than others to invent, improvise, make do with available resources, decide instantly on bold moves when he is in a tight spot. Thinking that he already knows, he will learn more slowly, display less flexibility. And the irony of history has willed, by virtue of the social situation of many Latin American countries, the assignment of precisely this vanguard role to students and revolutionary intellectuals, who have had to unleash, or rather initiate, the highest forms of class struggle.
