Abstract
This article is devoted to Thomas Piketty’s latest book, Capital and Ideology (2019). We begin by placing the book within the argument 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 coming to his theory of ideology. Finally, we will try to define the contours and limits of Piketty’s project of overcoming capitalism, ie. his vision of a just society, of a “participative socialism”, as it is presented in the last chapter of the book.
