Plato justifies the concentration and exercise of power for persons endowed with expertise in political governance. This article argues that this justification takes two distinctly different sets of arguments. The first is what I shall call his 'ideal political philosophy' described primarily in the Republic as rule by philosopher-kings wielding absolute authority over their subjects. Their authority stems solely from their comprehension of justice, from which they make political judgements on behalf of their city-state. I call the second set of (...) arguments Plato's 'practical political philosophy' underlying his later thought, where absolute rule by philosopher-kings is undermined by the impure character of all political knowledge. Whereas the complete comprehension of justice sanctions the absolute political power of those with this expertise, partial knowledge of justice disallows for such a large investment of power. Plato's practical political philosophy argues for a mixed theory of governance fusing the institutions of monarchy with democracy in the best practical city-state. Thus, Plato comes to realize the insurmountable difficulties of his ideal political thought, preferring a more practical political philosophy instead. (shrink)

Researchers working in the field of ecosystem services (ES) have long acknowledged the importance of recognising multiple values in ecosystems and biodiversity. Yet the operationalisation of value pluralism in ES assessments remains largely elusive. The aim of this research is to present a taxonomy of values and valuation methods to widen the evaluative space for ES. First, we present our preanalytic positions in regards to the values and valuation of ES. Second, we review different value definitions that we deem relevant (...) for the discussion of ES valuation. Third, we propose a taxonomy of ES values based on different conceptions of human-nature relationships. Finally, we present a taxonomy of different methods that can be used to recognise plural values in ES. This taxonomy for a plural valuation can help ES scientists and practitioners with their aim of representing people's multiple and context-specific ways of valuing nature. The taxonomy can also serve to pay broader attention to ES values that are overlooked or misrepresented in assessments that restrict their focus to monetary valuations. (shrink)

The journal Environmental Values is thirty years old. In this retrospective, as the retiring Editor-in-Chief, I provide a set of personal reflections on the changing landscape of scholarship in the field. This historical overview traces developments from the journal's origins in debates between philosophers, sociologists, and economists in the UK to the conflicts over policy on climate change, biodiversity/non-humans and sustainability. Along the way various negative influences are mentioned, relating to how the values of Nature are considered in policy, including (...) mainstream environmental economics, naïve environmental pragmatism, the strategic role of corporations, neoliberalism and eco-modernism/techno-optimism. At the same time core value debates around intrinsic value in Nature and instrumentalism remain relevant, along with how plural environmental values can be articulated and acted upon. Naturalness, human relations to non-humans, and Nature as other, remain central considerations. The broadening of issues covered by the journal (e.g. covering social psychology, sociology and political science), reflect the need to address both human behaviour and the structure of social and economic systems to confront ongoing social-ecological crises.

Economics takes an individualistic approach to human behaviour. This is reflected in the use of 'contingent valuation' surveys to conduct cost benefit analysis for economic policy evaluation. An individual's valuation of a policy is assumed to be unaffected by the burdens it places on others. We report a survey experiment to test this supposition in the context of climate change policy. Willingness to pay for climate change mitigation was higher when richer individuals were to bear higher costs than when, as (...) is usual, no explicit information was provided about cost distribution. This result is inconsistent with the usual interpretation of contingent valuation data. It also suggests that the data may be biased indicators of policy acceptance. Additional survey questions suggest that a collective mode of reasoning is common. (shrink)

The use of cost-benefit analysis (CBA) in environmental decision-making and the contingent valuation (CV) technique as input into traditional CBA to elicit environmental values in monetary terms has stimulated an extensive debate. Critics have questioned the appropriateness of both the method and the technique. Some alternative suggestions for the elicitation of environmental values are based on a social process of deliberation. However, just like traditional economic theory, these alternative approaches may be questioned on their implicit value judgements regarding the legitimacy (...) of the social-political organisation of the process of value elicitation. Instead of making assumptions a priori, research efforts should be focused on the processes by which actual public attitudes and preferences towards the environment can best be elicited and fed into environmental or other public policy decision-making. In the study presented in this paper, support was found for both the individual WTP based approach and a participatory social deliberation approach to inform the environmental decision-making process, suggesting that a combination of both approaches is most appropriate.
