Rousseau's nightmare has come true: farewell to goodness and justice. The philosopher who wrote a political work aimed at eliminating inequalities between people and making possible an individual freedom that respects others would fall into a complete depression in today's Trumpist world. In just a few decades, we have gone from "let's make love, not war" to proudly displaying hatred of difference. Identity (identities: individual, national, religious) has ceased to be an invitation to get to know the other and has become a hard protective shell. The mature Rousseau already suffered from the intolerance that has become omnipresent today.

Is Trump killing democracy? Are we witnessing a crime in real time? In a few decades, will we need a historian Carles Porta to elucidate the dark plot? Are we still in time to avoid the tragic death? Let us shed light on the darkness. And what better light than that projected by Voltaire, Rousseau, Diderot, Montesquieu and company three hundred years ago, during the Age of Enlightenment, when they taught us the joy of reasoning, thinking and feeling freely, when they instilled in us confidence in progress and science.
