Ever since environmental ethics began to take form as an academic discipline in the early 1970s, the notion of intrinsic value has occupied a prominent position within the field. Recently, however, various types of critique have emerged within EE against invoking this notion. Contrary to these critiques, I argue that appeals to intrinsic value are not problematic, given the reason-implying sense of 'intrinsic value' that is most relevant to EE. I further argue that also those who criticise 'intrinsic-value-talk' in EE (...) actually need this reason-implying concept of intrinsic value. However, once we realise that this is the sense of 'intrinsic value' that is most relevant to EE, it also becomes clear that it is the concept of a reason, rather than that of intrinsic value, that is most important to EE.

This dissertation concerns the location and nature of phenomenal qualities. Arguably, these qualities naively seem to belong to perceived external objects. However, we also seem to experience phenomenal qualities in hallucinations, and in hallucinations we do not perceive any external objects. I present and argue for a theory of the phenomenal qualities, "brain theory", which claims that all phenomenal qualities we experience are physical properties instantiated in the brain, regardless of whether they are experienced in veridical perceptions or in hallucinations. (...) I begin by more carefully identifying the phenomenal qualities, discussing how they are related to "qualia" and "phenomenal character". Then I present brain theory, and investigate its implications for the perceptual relations we stand in to external objects, noting that it is mostly neutral. I also compare brain theory to a similar theory of perception advocated by Bertrand Russell. Next, I provide an overview over the competing theories of phenomenal qualities, and relate them to theories of perception, such as representationalism, qualia theory, sense data theory and disjunctivism. The majority of my argumentation for brain theory focuses on arguing that the phenomenal qualities are instantiated in the brain, rather than on arguing that they are physical properties. Instead, I largely assume physicalism. However, even independently of the physicalism assumption, I show that we have reason to believe that phenomenal qualities are experienced in hallucinations, and that qualities experienced in hallucinations are instantiated in internal objects, such as our brains or sense data. In the first step towards this conclusion I argue that theories which deny that phenomenal qualities are experienced in hallucinations face serious problems. In the next step I argue that theories which deny that phenomenal qualities experienced in hallucinations are instantiated in internal objects face serious problems. Finally, an important part of the argumentation is my replies to objections against brain theory, including common sense objections and the "observation objection". From these conclusions, together with the physicalism assumption, I infer that we have reason to believe that brain theory is true about hallucinations. On this basis, I then argue, through a generalizing argument, that the same is the case for veridical perceptions. (shrink)

The distinction between anthropocentric and non-anthropocentric theories, together with the more fine-grained distinction between anthropocentrism, biocentrism and ecocentrism, are probably two of the most frequently occurring distinctions in the environmental ethics literature. In this essay I draw attention to some problematic aspects of the terminology used to draw these distinctions: the ‘centrism-terminology’. I argue that this terminology is ambiguous and misleading, and therefore confusing. Furthermore, depending on which interpretation it is given, it is also either asymmetric and non-inclusive, or superfluous. (...) Although I find it unlikely that the centrism-terminology will be abandoned, I end the essay by providing a suggestion for an alternative way to categorise theories in environmental ethics. (shrink)

Environmentalists care about nature. Often, they reason and act as if they consider nature to be valuable for its own sake, i.e., to have non-instrumental value. Yet, there is a rather widespread reluctance, even among environmentalists, to explicitly ascribe such value to nature. One important explanation of this is probably the thought that it would be mysterious in one way or another if nature possessed such value. In addition, Bryan Norton’s influential convergence hypothesis states that, from a practical point of (...) view, it makes no or little difference whether we ascribe non-instrumental value to nature, given the depth and variety of instrumental value that it possesses. In this paper we provide a counterfactual argument, applying to anyone who genuinely cares about nature, for endorsing non-instrumental value in it. Even if we accept, for the sake of argument, something like the convergence hypothesis, relying on nature’s instrumental value for preservational purposes is risky business for environmentalists. We also briefly consider the mysteriousness-objection to non-instrumental value in nature. We show that with respect to most accounts of non-instrumental value, there is nothing particularly mysterious about nature possessing such value. (shrink)
