A magnificent collector's edition with artist's cover, laser cut paper, firm book like a box. Blue Jaspage. What do we mean by happiness? Do we depend on our genes, luck, our sensibility? Is it a lasting state or a series of fleeting pleasures? Is it only subjective? Should we look for it? Can we cultivate it? Can we cultivate it? Can we coexist in pain and happiness? To try to answer these questions, Frederic Lenoir proposes a philosophical journey, joyful and full of flavors. A stimulating walk in the company of the great wise men of the East and the West, or we will cross the garden of pleasures with Epicure, or we will hear the laughter of Montaigne and Chuang-tse, will meet the peaceful smile of Buddha and Epictete, or we will taste the joy of Spinoza and Etty Hillesum. A living journey, reinvigorating, punctuating, punctuating with concrete examples and last discovers, to help us to learn and learn more about neuroscience.
