This thought-provoking book explores the concept of Happiness from various perspectives, drawing on ancient Greek, Chinese and Hindu thought, Judaism, Christianity, Islam, mythology, literature, arts, and Quantum physics. It offers an insightful exploration of the concept of Happiness through the lens of various civilisations, arts and sciences. The author proposes to look at many definitions of Happiness as they appear in ancient Greek philosophy, Chinese and Hindu thought, Judaism, Christianity, Islam, and their respective mystical traditions. Then he examines the notion of Happiness in mythology and contemporary literature, primarily through the eyes of Lewis Carroll, and then of two opposing figures: Dostoevsky and Marquis de Sade. The first is as an immense moralist, a fine analyst of the human psyche, and a representative of orthodoxal Christianism, and the second, is an atheist libertine associated with the radical rationalist trend. Finally, the author also devoted a chapter to Happiness in the arts and reserved the last words to the scientific approach to Happiness, with a particular emphasis on Quantum physics.
