Abstract

A teleological approach to deciding how we should act underlies the attempted extension of neo-classical economics to environmental issues, with its emphasis on comparative valuation in monetary terms. Such an extension fails because, in the environmental sphere, there are powerful reasons for denying commensurability of the relevant values. But this denial then tends to undercut any weighing of environmental goods. In response to this difficulty, the paper seeks to develop an account of the weighing of goods which would enable us to recognise value as a human creation, while also grounding it in an ecological unity with the wider life of nature.
