Hi Corrado, sorry for the delay. I am not always notified of new comments. Here is one explanation of the quote to which I think you are referring: https://www.centreforoptimism.com/Pessimism-of-the-Intellect-Optimism-of-the-Will. Actually it comes from the French novelist Romain Rolland but Gramsci made it famous. Looking forward to more of your work!
