Abstract
This article analyzes Thomas Piketty's latest book, Capital and Ideology (2020). We begin by placing the work in the context of the thesis developed by the author in his previous works, before pointing out a number of limitations. We first question Piketty's way of thinking about capitalism, before discussing his theory of ideology. Finally, we will try to define the scope and limits of Piketty's vision of overcoming capitalism, that is, his vision of a just society, a "participatory socialism", as it is presented in the last chapter of the book.
