Dr David Macarthur

IAS Fellow at University College, Durham University (January - March 2016)



David Macarthur is Associate Professor in Philosophy at the University of Sydney, Australia. His research is mostly in the areas of contemporary pragmatism, skepticism, liberal naturalism, the continuing relevance of Wittgenstein’s thought in resisting scientistic attacks on ordinary life, and the philosophy of art (especially architecture, film and photography). Following a short career in medicine, including a stint as in Internist in an Emergency Room, Dr Macarthur completed a PhD at Harvard on the topic of external world skepticism under the supervision of Stanley Cavell, Hilary Putnam and Warren Goldfarb. He then taught for a year at Tufts University (USA) before taking up a post-doctoral research fellowship at Macquarie University (Australia) where, in collaboration with Professor Mario De Caro (Roma Tre), he played a leading role in the development of the humanist idea of a liberal naturalism as a more promising philosophical option than either of the traditional alternatives of scientific naturalism (in any of its varieties) or supernaturalism (e.g. theism). The idea of liberal naturalism is gaining increasing attention as evidenced, e.g., by an entry in the prestigious The Cambridge Dictionary of Philosophy (ed. Robert Audi).

Dr Macarthur has published widely in leading philosophical journals and books and has co-edited three books with Professor Mario De Caro (Roma Tré): Naturalism in Question (Harvard University Press, 2004); Naturalism and Normativity (Columbia University Press, 2010); and Philosophy in an Age of Science: Recent Writings of Hilary Putnam (Harvard University Press, 2012). He is currently editing Pragmatism as a Way of Life: On the Lasting Legacy of James and Dewey by Hilary & Ruth-Anna Putnam (Harvard University Press). Together with Professor Stephen Hetherington he is also editing a collection titled Living Skepticism (Brill). At Sydney University he has won two International Collaboration Research Awards (Warren Goldfarb 2008; Charles Travis 2013). He has held two visiting appointments in the Philosophy Departments at Tel Aviv University and University of Paris 8.

Whilst at the IAS Dr Macarthur will collaborate with Professor Andy Hamilton and other members of the Philosophy Department to explore two rationally respectable ways of acquiring beliefs about empirical matters that are not well thought of in terms of the traditional idea of (scientific) evidence. The first case concerns being able to discern the character and genuineness of another’s gestures and non-verbal expressions of feeling and emotion. Here one relies on “imponderable evidence” (Wittgenstein), a form of non-scientific evidence. The second case concerns acquiring beliefs (or knowledge) by way of testimony where the reason for the belief (or knowledge) one acquires is not a matter of evidence but, rather, of accepting another’s word, trusting them. This project thus draws attention to cases of subjective evidence and non-evidential reasons for belief that tend to be largely overlooked in the philosophical literature which reflects a widespread tendency to focus exclusive attention on natural science as the pre-eminent model for acquiring knowledge and justified belief. Attending to these non-standard cases is an exploration of “second-personal space”, the interpersonal realm of I–thou relationships characterizable in pragmatic normative terms of responsibilities and commitments to others as well as of others to oneself.


Public Lecture - Can there be Intuitive Evidence?

23rd February 2016, 17:30 to 18:30, Senate Suite, University College


In contemporary culture we invariably think that our beliefs and our knowledge should be solely based on objective evidence: the sort of evidence that science studies and produces; the sort that is, as the OED puts it, “available”, meaning that it is accessible to anyone under the right circumstances. In this talk Dr David Macarthur's aim will be to argue that we have allowed this scientific conception of objective evidence to obscure another important category of evidence from view. He will call it intuitive evidence. This kind of evidence is subjective, non-scientific, and not universally accessible but only available to those who have the requisite ‘eye’ (or ‘ear’ or ‘nose’) for it.
