It is undeniable that human beings seek happiness and have difficulties finding it. It is a phenomenon that is not new, since since the most remote Antiquity man has wondered about what happiness is, where it resides and how to achieve it. For the Greeks, a people of deep pessimism, the search for happiness (eudaimonia) was a traditional theme of philosophy and it was precisely in Greece that the doctrine of happiness of Epicurus (341-270 BC) arose, a cursed and manipulated author ( as his admirer Nietzsche) and that he has perhaps been the thinker who has addressed the question of eudaimonia with more lucidity. His doctrine, with evangelical eagerness, seeks and promises its followers happiness through pleasure (hedoné), self-sufficiency (autarky), friendship (philía) and mental calm (ataraxia), offering itself as a medicine against the pain of flesh and the sufferings of the mind. But Epicurean hedonism, which by its limitation is almost asceticism and which harmonizes well with the ancient Apollonian maxim that wisdom consists in moderation and the knowledge of limits, is totally removed from both the tyranny of the "happycracy" and from the harmful culture of unbridled and empty desire of contemporary postmodernity and, for this very reason, for constituting an effective therapy against the ills that afflict the nihilistic human being of the neoliberal era, Epicurus's timeless proposal for authentic happiness deserves to be known for all.
