Research summary

My research primarily concerns social-political philosophy, epistemology, ethics, and the philosophy of language. These topics figure centrally in the following:


Below are descriptions of particular interests in these research areas and some representative papers in each area:

  • Social-Political Philosophy. I am especially interested in the epistemic role of public discourse, the justification/critique of democracy, social-political conditions for knowledge and freedom of belief, civil and uncivil dissent. See for example,


  • Epistemology. I am especially interested in epistemic norms, the nature of doxastic agency and virtue, the nature of belief, self-knowledge, and the role of ideology and propaganda on belief. See for example,

    • “Social Foundations for Epistemic Normativity” in Belief, Agency, and Knowledge, Oxford University Press (2022).
    • “Epistemic Normativity and Doxastic Agency” Noûs 52 (2018).
    • “Ought to Believe” Journal of Philosophy 105 (2008).


  • Ethics. I am especially interested in the discursive role of ethical statements, the meaning of ‘ought’, the nature of rules and norms, the moral psychology of action, and the possibility of normative knowledge. See for example,


  • Philosophy of Language. I am especially interested in the theory of meaning, theories of truth, the interaction between semantics and metasemantics, the meaning of deontic modals and imperatives, and applied speech-act theory. See for example,

Knowledge exchange

I am leading the Responsible Debate Project for the Young Academy of Scotland, who published a Charter for Responsible Debate, which you can view and sign in support here:  We have hosted numerous public events, including workshops at The Royal Society of Edinburgh, the Edinburgh Fringe Festival, and the Scottish Parliament.

With the Young Academy of Scotland, I published a report Charter for Responsible Debate: Discussing contentious issues with common purpose (edited with Alice König, John O'Connor & Peter McColl) which contains two pieces I helped to write:

  • “Participatory Democracy and Responsible Debate,” which you can read in blog form here
  • “Social Media and Responsible Debate” (with Peter McColl), which you can read in blog form here

I was a member of the Royal Society of Edinburgh’s Post-Covid Futures Commission in 2020-21, contributing to the working group on Public Debate & Participation, for whom I wrote a few pieces on expertise and democracy in public policy.  

I developed the Wireless Philosophy video “Obligations to Obey the Law” (2018) and “Civil Disobedience” (2020).

I wrote “Politics in Scotland” (with Alice König and Sarah Virgo) 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 2017) on the basis of this course.

Past project grants

In 2020-22, I was a British Academy Mid-Career Fellow, working on a project called "Thinking for Ourselves: Freedom in Believing and Social Norms for Belief." This project aimed 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 was to complete a book articulating and motivating a novel philosophical theory of doxastic agency 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.

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).
