Abstract

On the dominant economic approach to environmental policy, environmental goods are conceptualised as forms of capital that provide services for human well-being. These services are assigned a monetary value to be weighed against the values of other goods and services. David Wiggins has offered a set of arguments against central assumptions about the nature of well-being, practical reason and ethical deliberation that underpin this dominant economic approach. In this paper I outline these arguments and consider their implications for understanding ethical demands across generations. The paper focuses, in particular, on their implications for understanding the nature and requirements of sustainability.
