Gilberto Lopes, with this profound and provocative study based on an ingenious imaginary dialogue between Alexis de Tocqueville (1805-1859) and Karl Marx (1818-1883) on democracy, presents us with a disturbing work on one of the most important debates in today's political world.This work arises from a practical concern, from a life experience and a political restlessness, but also from a theoretical curiosity to make a journey inspired by the work of these two great thinkers who approached the history of their time with particular acuity and erudition.
