This book centres on 'value' in the sense of what it is worth having or being in life. It first investigates how judgements of values manifest themselves, whether there can be evidence for them and whether a realistic account is appropriate. It then goes on to examine the relations between judgments of value and those of what it is best to do, and whether value has any proper role in social policy. Kupperman rejects the notion that there is any one primary value, and argues instead for a pluralistic understanding of value. He contends that value must be viewed as strongly contextual; the value of a particular set of experiences in someone's life can depend heavily on how they fit in or provide contrast with other elements.
