Abstract
The chapter aims to provide at least a partial analysis of the word ‘happiness’ as it is used in everyday language. The author tries to make clear exactly what we are looking for in a theory of happiness and then goes on to argue for a particular theory. The theory that the author endorses is a composite of affective and cognitive elements. The chapter looks at four monistic theories of happiness before showing why each is insufficient. It considers two affective accounts of happiness: sensory hedonism and emotional state theory. The chapter then discusses two cognitive accounts. It shows that whole life satisfaction is not a constituent of superlative happiness, though whole life satisfaction is perhaps the most common understanding of happiness in both social science and philosophical literature. The author argues for a composite view of happiness that includes sensory pleasure, positive emotional states, and positive propositional attitudes.
