To be intrinsically valuable means to be valuable for its own sake. Moral philosophy is often ethically anthropocentric, meaning that it locates intrinsic value within humans. This paper rejects ethical anthropocentrism and asks, in what ways might nonhumans be intrinsically valuable? The paper answers this question with a wide-ranging survey of theories of nonhuman intrinsic value. The survey includes both moral subjects and moral objects, and both natural and artificial nonhumans. Literatures from environmental ethics, philosophy of technology, philosophy of art, (...) moral psychology, and related fields are reviewed, and gaps in these literatures are identified. Although the gaps are significant and much work remains to be done, the survey nonetheless demonstrates that those who reject ethical anthropocentrism have considerable resources available to develop their moral views. Given the many very high-stakes issues involving both natural and artificial nonhumans, and the sensitivity of these issues to how nonhumans are intrinsically valued, this is a vital project to pursue.

This paper describes some likely semiotic consequences of genetic engineering on what Gregory Bateson has called “the mental ecology” of future humans, consequences that are less often raised in discussions surrounding the safety of GMOs. The effects are as follows: an increased 1) habituation to the presence of GMOs in the environment, 2) normalization of empirically false assumptions grounding genetic reductionism, 3) acceptance that humans are capable and entitled to decide what constitutes an evolutionary improvement for a species, 4) perception (...) that the main source of creativity and problem solving in the biosphere is anthropogenic. Though there are some tensions between them, these effects tend to produce self-validating webs of ideas, actions, and environments, which may reinforce destructive habits of thought. Humans are unlikely to safely develop genetic technologies without confronting these escalating processes directly. Intervening in this mental ecology presents distinct challenges for educators, as will be discussed. (shrink)

Diversity is an important ethical concept, but it is almost exclusively studied within two domains: biodiversity and diversity of sociological attributes such as race and gender. We provide a general study of the intrinsic value of diversity. We survey prior literature on the intrinsic value of biodiversity and sociological diversity in search of insights relevant to the intrinsic value of all types of diversity. We then present three thought experiments designed to clarify intuitions about the intrinsic value of small amounts (...) of diversity, large amounts of diversity, and diversity as compared to other intrinsic values. We find that many types of diversity are intrinsically valuable at both small and large amounts, but that diversity may be a weak intrinsic value in comparison to others. Noting that diversity can be defined in many ways, we propose that, for purposes of moral evaluation, diversity should be defined to include both a diversity of individual elements within a group and a diversity of the overall patterns or structures of the group. Some of our findings about the intrinsic value of diversity are tentative, indicating that moral intuitions about diversity are sometimes ambiguous and would benefit from further study. (shrink)
