Research summary

My research concerns:

  • Social-Political Philosophy, especially the epistemic role of public discourse, the justification/critique of democracy, social-political conditions for knowledge and freedom of belief, civil and uncivil dissent. 
  • Epistemology, especially epistemic norms, the nature of doxastic agency and virtue, the nature of belief, self-knowledge, and the role of ideology and propaganda on belief.
  • Ethical theory, especially the discursive role of ethical statements, the meaning of ‘ought’, the nature of rules and norms, action theory, and normative knowledge.
  • Philosophy of Language, especially the theory of meaning, theories of truth, the interaction between semantics and metasemantics, the meaning of imperatives, and speech-act theory.

For an overview of my research, my inaugural professorial lecture is a good place to start :

My book The Meaning of 'Ought': Beyond Descriptivism and Expressivism in Metaethics was published by Oxford University Press in 2016.

My textbook What Is This Thing Called Metaethics? was published with Routledge in 2016.

I edited  Deontic Modality (with Nate Charlow) for Oxford University Press in 2016.

Knowledge exchange

I am a member of the Royal Society of Edinburgh's Post-Covid Futures Commission, contributing to the working group on Public Debate & Participation.

I am leading the Responsible Debate Project for the Young Academy of Scotland, whose initial workshop for a draft charter of responsible public debate for Scotland was held on May 13, 2019, with follow up events at the Edinburgh Fringe Festival and the Festival of Politics at the Scottish Parliament.

I developed the Wireless Philosophy video "Obligations to Obey the Law" (2018):

With Alice König and Sarah Virgo, I wrote “Politics in Scotland” for the Young Academy of Scotland Brexit Report (2017):

I organised Should You Trust What You Hear (About Science): An Enlightenment Debate: Hume vs. Reid, a public debate at the Edinburgh International Science Festival in 2015

I helped to develop and continue to contribute to Introduction to Philosophy a Massive Open Online Course (MOOC):

With members of the MOOC team, we have developed a popular book Philosophy for Everyone (Routledge 2014, expanded 2nd edition 2016) on the basis of this course.

Project activity

Latest research grants/projects

Current project grants

In 2020-22, I am a British Academy Mid-Career Fellow, working on a project called "Thinking for Ourselves: Freedom in Believing and Social Norms for Belief." This project aims to improve understanding of how our beliefs are formed and contribute to wider agreement of standards for constructive contribution to public debate. The main research goal is to complete a book articulating and motivating a novel philosophical theory of freedom of belief and norms for belief. This philosophical theory also informs and motivates civic outreach efforts, which are part of my ongoing work with the Young Academy of Scotland to create a charter for responsible public debate.

Past project grants

In 2015-17, I was the PI on Foundations of Normativity ( an International and Interdisciplinary Research Grant funded through the Institute for Advanced Studies in the Humanities, to pursue an international and interdisciplinary research network across Philosophy, Law, and Politics between University of Edinburgh and several other institutions. This resulted in four annual Foundations of Normativity Workshops and associated events: Epistemic, Legal, and Moral Rules (2015), Moral and Legal Normativity (2016), Political, Legal, and General Norms (2017), Contemporary Moral Epistemology (2018).

In 2010-11, I was an AHRC Early-Career Fellow, working on a project called "The Expressive Role of 'Ought'". The goal of this project was to work on a novel semantics for the normative term par excellence 'ought' and to use this to develop foundations for a new metanormative theory of meaningfulness of normative discourse. This project resulted in my book The Meaning of 'Ought': Beyond Descriptivism and Expressivism in Metaethics (Oxford University Press, 2016).
