I am a Professor of Philosophy at the University of Oxford, where I served as the Wykeham Professor of Logic for over two decades. My academic career has spanned prestigious roles at Edinburgh and Trinity College Dublin, alongside visiting professorships at Yale, MIT, and Princeton. My global impact is recognized through fellowships in the British Academy and the American Academy of Arts and Sciences. I was honored with the 2024 Lauener Prize for my outstanding oeuvre and overall contribution to analytical philosophy. I have shaped contemporary epistemology with my "Knowledge First" approach, most notably in my landmark book Knowledge and its Limits. In the realm of logic, my work Vagueness remains a definitive text on the epistemic limits of language and boundaries. I have also redefined how we view the discipline itself through my influential work, The Philosophy of Philosophy. My contribution to metaphysics is highlighted by Modal Logic as Metaphysics, exploring the nature of necessity and possibility. I have recently released released Overfitting and Heuristics in Philosophy(2024). I have published over 200 articles.
The knowledge-first approach that I've been developing is a radical contrast with the way that most people had been doing epistemology before. In the decades leading up to that, they were mainly focused on belief and building up from belief to maybe true belief and further sorts of states. From my point of view, there's nothing specially good just in itself about acting on your beliefs. Because if your beliefs are completely wrong, then acting on them is maybe a disaster.
If one thinks about imagination from a broadly evolutionary perspective, it is quite an elaborate faculty that humans have, and maybe other animals as well. The way that I'm understanding imagination should lead us to value it even more than we do, and not to think of it as some sort of optional extra that you can use in your free time.
Philosophical paradoxes are very often the result of what are called heuristics by psychologists: simple, quick, easy ways of answering questions or solving problems.
