current project (2022-2025)
The Normativity of Conventional Norms
Informal conventional norms regulate many aspects of our lives. They shape our collective and individual behaviour and can be seen as the glue of society. At the same time, these norms can function to maintain an unjust status quo and prevent social progress. It is therefore important to examine to what extent and under what conditions conventional norms form legitimate restrictions on our actions. An account of the normative status of the social rules we live under will both build on and contribute to a fundamental theory of our reasons for action. This project provides a philosophical investigation of conventional norms in two parts. The first aim is to examine whether and how conventional norms provide reasons for action. This research will include a thorough interdisciplinary analysis of the nature and role of these norms. The second aim is to use these insights to develop a comprehensive theory of normativity in general.
This project is funded by the programme “postdoctoral fellowships” within the Excellence Strategy of Universität Hamburg. It is connected to the university’s emerging research field ‘Grounds, Norms, Decisions’.

PhD thesis
Demystifying Normativity: Morality, Error Theory, and the Authority of Norms

We are subject to many different norms telling us how to act, from moral norms to etiquette rules and the law. While some norms may simply be ignored, we live under the impression that others matter for what we ought to do. How can we make sense of this normative authority some norms have?
The aim of this thesis is to unravel the mystery of normativity. It uncovers and objects to the influential non-natural conception of it, arguing that we can capture normativity with natural properties. In particular, it explores how the authority of norms can be explained by the commitments of the people subject to them. In connection to this, it challenges the conceptual claim behind the view that all moral judgements are mistaken. Finally, it reveals that treating morality as a mere fiction has revolutionary practical implications. This emphasises the importance of the overall conclusion: we need not conceive of either moral or normative properties as too mysterious to exist.
