Dr Alexander Geddes

BA KCL, BPhil Oxf, PhD UCL


For the 2023-24 academic year, I will be a Departmental Lecturer in Philosophy of Mind, at St Hilda's and the Faculty of Philosophy. Previously, I have held positions at Exeter College, Oxford; King's College London; the University of Southampton; the Centre for Philosophical Psychology, University of Antwerp; and The Queen's College, Oxford. For my education, I studied Philosophy at University College London (PhD), Oriel College, Oxford (BPhil), and King's College London (BA).

My primary research project examines connections between the nature of human beings and the nature of the human mind. But my interests are wide-ranging, and I have written on various issues in Metaphysics, Philosophy of Mind, Metaphilosophy, Epistemology and the Philosophy of Biology.

For Prelims, I teach Introduction to Logic and General Philosophy. For Finals, I currently offer tutorials in Philosophy of Mind, Knowledge & Reality, Philosophy of Cognitive Science and Philosophy of Logic & Language. This year, I will also be providing undergraduate lectures in Philosophy of Mind, and teaching a graduate class on Self and Mind.

I am currently developing a research project with two complementary strands. In the first strand, I argue that there are various important ways in which an account of our nature must be prior to an account of the nature of our minds, and that recognising this priority has the potential to resolve a number of intractable debates within the philosophy of personal identity. In the second, I raise and address various challenges that face any serious attempt to develop an account of our nature that has the envisaged priority. The former draws on ideas that grew out of my doctoral research, concerning the preservation, realisation and unity of the human mind. The latter draws on work I began as a Research Fellow on the ERC-funded BUMP (Better Understanding the Metaphysics of Pregnancy) project, concerning debates within the Philosophy of Biology about the nature of organisms.

Alongside work for the project above, I also have papers in progress on suspending judgment and on the significance of fission cases for accounts of persisting objects. And in the past, I have published work on judgments about thought experiments; on consciousness and self-consciousness; on the metaphysics of the past; on the mereology of pregnancy; and on the self and the unity of consciousness.
