"Marco Revelli is a scholar who combines intellectual commitment with passion. You see this in Left Right, which could also have been called Adventures and Mishaps of the Left and Right towards the unknown. The result is a lively and highly-interesting work. Revelli sets a threefold task: to identify Left and Right, trace their evolution and reflect on what remains of them in a world such as the one we live in today. The burning question is: once the respective identities have been lost, what remains, what kind of disorder and what tasks await a Left that many imagine is facing its final decomposition?"

What is dramatically absent seems instead to be the solutions and politicians willing to take up the challenge.
