Perhaps few terms are as hackneyed and have been used as much as freedom. Without apparent double meanings, the result of a consensus that needs no proof, modern societies shout from every corner that definitely and without a doubt "we are free." But what does "to be free" mean here? To answer this question, this book develops a long philosophical and political investigation about the concept of freedom from Enlightenment thought. And precisely against her naturalization, the author questions her alleged indisputable support: the individual and the State. Starting, then, from Marx's critique, from Spinoza's denial of free will, from feminist questioning and from the rich conceptual machine of Deleuze and Guattari, she proposes a conception of subjectivity, in which the "common" and the usual? in political action, they become the real key to freedom. In this framework, freedom translates into desire: the desire for the power of living, the desire for alliance with others, the desire to build the conditions for collective liberation. Far from the solipsistic individualism of liberal freedom that can only think of the collective as a pact, this reading allows us to understand a new subjective constitution that takes advantage of and reinforces that active energy of living that, as Galcerán demonstrates, can only occur in that space always to build what we call the ?common?.
