Is it fair to leave the next generation a public debt? Is it defensible to impose legal rules on them through constitutional constraints? From combating climate change to ensuring proper funding for future pensions, concerns about ethics between generations are everywhere. In this volume sixteen philosophers explore intergenerational justice. Part One examines the ways in which various theories of justice look at the matter. These include libertarian, Rawlsian, sufficientarian, contractarian, communitarian, Marxian and reciprocity-based approaches. In Part Two, the authors look more specifically at issues relevant to each of these theories, such as motivation to act fairly towards future generations, the population dimension, the formation of preferences througheducation and how they impact on our intergenerational obligations, and whether it is fair to rely on constitutional devices.
