The concept of dignity plays a foundational role in the more recent versions of Martha Nussbaum’s capabilities theory. However, despite its centrality to her theory, Nussbaum’s conception of dignity remains under-theorised. In this paper we critically examine the role that dignity plays in Nussbaum’s theory by, first, developing an account of the concept of dignity and introducing a distinction between two types of dignity, status dignity and achievement dignity. Next, drawing on this account, we analyse Nussbaum’s conception of dignity and (...) contrast it with Kant’s conception of dignity. On the basis of this comparison between Nussbaum and Kant, we highlight tensions between Nussbaum’s Aristotelianism, which is central to her conception of dignity, and her commitment to political liberalism. This leads us to conclude that Nussbaum’s claim that her conception of dignity is only a partial political conception is implausible and that her conception of dignity seems to commit her to a satisficing form of perfectionist liberalism.

Kant says that it can be rational to accept propositions on the basis of non-epistemic or broadly practical considerations, even if those propositions include “transcendental ideas” of supersensible objects. He also worries, however, about how such ideas (of freedom, the soul, noumenal grounds, God, the kingdom of ends, and things-in-themselves generally) acquire genuine positive content in the absence of an appropriate connection to intuitional experience. How can we be sure that the ideas are not empty “thought-entities (Gedankendinge)”—that is, speculative fancies (...) that do not and perhaps even cannot have referents in reality? In this paper I argue for an account of the fundamental problem here (i.e. that it is based in a concern about whether or not the objects of such ideas are "really possible" in Kant's technical sense). I then critically evaluate Kant's three proposed solutions to the problem. The third one involves an appeal to the complicated doctrine of "symbolization" that becomes prominent in Kant's later works. -/- . (shrink)

One argument used by detractors of human embryonic stem cell research (hESCR) invokes Kant's formula of humanity, which proscribes treating persons solely as a means to an end, rather than as ends in themselves. According to Fuat S. Oduncu, for example, adhering to this imperative entails that human embryos should not be disaggregated to obtain pluripotent stem cells for hESCR. Given that human embryos are Kantian persons from the time of their conception, killing them to obtain their cells for research (...) fails to treat them as ends in themselves. (shrink)

Can nonhuman animals and artificial intelligence (AI) entities be attributed moral agency? The general assumption in the philosophical literature is that moral agency applies exclusively to humans since they alone possess free will or capacities required for deliberate reflection. Consequently, only humans have been taken to be eligible for ascriptions of moral responsibility in terms of, for instance, blame or praise, moral criticism, or attributions of vice and virtue. Animals and machines may cause harm, but they cannot be appropriately ascribed (...) moral responsibility for their behavior. This thesis challenges the conventional paradigm by proposing an alternative approach where moral agency is conceived as the competence to participate in moral responsibility practices. By shifting focus from intra-individual to contextual and socially situated features, this practice-focused approach appears to make the attribution of moral agency to nonhuman animals and AI entities more plausible than commonly assumed. Moreover, considering the current and potential future prevalence of nonhuman animals and AI entities in everyday settings and social contexts, a potential extension of moral agency to such entities could very well transform our social, moral, and legal practices. Hence, this thesis proposes that the attribution or withholding of moral agency to different entities should be carefully evaluated, considering the potential normative implications. (shrink)

In this paper I discuss the problem of the Kantian line. The problem arises because the locus of value in Kantian ethics is rationality, which (counterintuitively) seems to entail that there are no duties to groups of beings like children. I argue that recent attempts to solve this problem by Wood and O’Neill overlook an important aspect of it before posing my own solution.

Despite the moral underpinnings of Karl Popper’s philosophy, he has not presented a well-established moral theory for critical rationalism (CR). This paper addresses the ontological status of _moral agents_ as part of a research program for developing a moral theory for CR. It argues that moral agents are _selves_ who have achieved the cognitive capacity of _personhood_ through an evolutionary scenario and interaction with the environment. This proposal draws on Popper’s theory of the self and his theory of three worlds, (...) which offer both epistemological and ontological insights into the emergence and evolution of _moral agents_. The paper also discusses some of the consequences of this proposal for the _objectivity_ and _criticizability_ of moral judgments and the moral agency of artificial intelligence. It concludes by suggesting some directions for future research on the epistemological and ontological problems of ethics in CR. (shrink)
