"Ought" and Error

The moral error theory generally does not receive good press in metaethics. This paper adds to the bad news. In contrast to other critics, though, I do not attack error theorists’ characteristic thesis that no moral assertion is ever true. Instead, I develop a new counter-argument which questions error theorists’ ability to defend their claim that moral utterances are meaningful assertions. More precisely: Moral error theorists lack a convincing account of the meaning of deontic moral assertions, or so I will argue

Metasemantics, Moral Realism and Moral Doctrines

In this paper, I consider the relationship between Matthew Kramer’s moral realism as a moral doctrine and expressivism, understood as a distinctly non-representationalist metasemantic theory of moral vocabulary. More precisely, I will argue that Kramer is right in stating that moral realism as a moral doctrine does not stand in conflict with expressivism. But I will also go further, by submitting that advocates of moral realism as a moral doctrine must adopt theories such as expressivism in some shape or form. Accordingly, if you do not want to accept positions such as expressivism, you cannot defend moral realism as a moral doctrine. Similarly, if you want moral realism to compete with expressivism, you cannot accept Kramer’s take on moral realism either. Hence, moral realism as a moral doctrine stands and falls with theories such as expressivism, or so I shall argue

What’s Wrong with Relaxing?

In his new book Unbelievable Errors, Bart Streumer argues that there is no way around the result that all metaethical views other than the error theory either fail for the same reasons as metaphysical normative realism, or for the same reasons as expressivism. In this contribution, I seek to show that this is false: We can eschew this result by ‘relaxing’ about normative truths. Even if Streumer were right about the fate of metaphysical normative realism and expressivism, then, relaxed realists can avoid the problems he raises

Quasi-Realismus

This chapter provides an introductory overview of quasi-realism and its key challenges

Error-Theory, Relaxation and Inferentialism

This contribution considers whether or not it is possible to devise a coherent form of external skepticism about the normative if we ‘relax’ about normative ontology by regarding claims about the existence of normative truths and properties themselves as normative. I answer this question in the positive: A coherent form of non-normative error-theories can be developed even against a relaxed background. However, this form no longer makes any reference to the alleged falsity of normative judgments, nor the non-existence of normative properties. Instead, it concerns a specifically inferentialist construal of error-theories which suggests that error-theorists should abstain from any claims about normative ontology to focus exclusively on claims about the inferential role of normative vocabulary. As I will show, this suggestion affords a number of important advantages. However, it also comes at a cost, in that it might not only change the letter, but also the spirit of traditional error-theories

Expressivism, Minimalism and Moral Doctrines

Quasi-realist expressivists have developed a growing liking for minimalism about truth. It has gone almost unnoticed, though, that minimalism also drives an anti-Archimedean movement which launches a direct attack on expressivists’ non-moral self-image by proclaiming that all metaethical positions are built on moral grounds. This interplay between expressivism, minimalism and anti-Archimedeanism makes for an intriguing metaethical encounter. As such, the first part of this dissertation examines expressivism’s marriage to minimalism and defends it against its critics. The second part then turns to the anti-Archimedean challenge to expressivism and shows how to ward off this challenge by securing expressivism’s non-moral, metaethical status without having to abandon minimalism about truth

Relaxing about Moral Truths

As with all other moral realists, so-called relaxed moral realists believe that there are moral truths. Unlike metaphysical moral realists, they do not take themselves to be defending a substantively metaphysical position when espousing this view, but to be putting forward a moral thesis from within moral discourse. In this paper, I employ minimalism about truth to examine whether or not there is a semantic analysis of the claim ‘There are moral truths’ which can support this moral interpretation of one of moral realism’s key theses. My results are both discouraging and encouraging: Whilst I will argue that the claim ‘There are moral truths’ cannot be shown to be both moral and capable of demarcating relaxed realism from irrealism on the basis of a convincing semantic analysis that would be compatible with relaxed commitments, the moral interpretation of moral realism can be secured by modifying our understanding of what distinguishes relaxed realism from error-theoretic irrealism. Yet, we will see that this moral interpretation of moral realism does not ‘tumble out’ of the semantics provided for its central claims. Rather, hard work needs to be done before we can fully relax

Metasemantics for the Relaxed

In this paper, I develop a metasemantics for relaxed moral realism. More precisely, I argue that relaxed realists should be inferentialists about meaning and explain that the role of evaluative moral vocabulary is to organise and structure language exit transitions, much as the role of theoretical vocabulary is to organise and structure language entry transitions

Auf die Couch: Beziehungsprobleme zwischen Rational Choice und Politischer Psychologie

Political psychology and rational choice approaches are often regarded as standing in direct competition with one another. In this paper, we put this postulated rivalry to the test by examining the conditions which would need to be fulfilled so as to set up a conflict between political psychology and rational choice. Since our analysis shows that the perceived competition rests on a mistaken conception of the respective approaches, we argue that our main aim should be to investigate how to combine these approaches so as to maximise their fruitfulness for political science

Of animals, robots and men

Domesticated animals need to be treated as fellow citizens: Only if we conceive of domesticated animals as full members of our political communities can we do justice to their moral standing - or so Sue Donaldson and Will Kymlicka argue in their widely discussed book Zoopolis. In this contribution, we pursue two objectives. Firstly, we will reject Donaldson and Kymlicka's appeal for animal citizenship. We will do so by submitting that far from paying due heed to their moral status, regarding animals as citizens misinterprets their moral qualities and thus risks treating them unjustly. Secondly, we will suggest that Donaldson and Kymlicka's reinforced focus on membership should draw our attention to the moral standing of a further "species" living in our midst, namely robots. Developments within artificial intelligence have advanced rapidly in recent years. With robots gaining ever greater capacities and abilities, we need to ask urgent questions about the moral ramifications of these technical advances
