In this brief history, philosopher Nicholas White reviews 2,500 years of philosophical thought about happiness. Addresses key questions such as: What is happiness? Should happiness play such a dominant role in our lives? How can we deal with conflicts between the various things that make us happy? Considers the ways in which major thinkers from antiquity to the modern day have treated happiness: from Plato s notion of the harmony of the soul, through to Nietzsche s championing of conflict over harmony. Relates questions about happiness to ethics and to practical philosophy.
