What paulistanos read on the metro

In Sao Paulo last year (in our Northern summer, their Southern winter), I loved the book vending machines in the metro.
It seems a mixture of peaceful non-resistance, sly cunning and the law is what people want to get them through those commutes...
(The top right book is of Brazilian law, the middle shelf has Machiavelli and Gandhi, and Machiavelli's The Prince is below the Gandhi too:)
