Jonas Olson is Reader in Practical Philosophy at Stockholm University. He received his PhD from Uppsala University in 2005. In 2005-2008 he was a Fellow at Brasenose College and Departmental Lecturer in Moral Philosophy at the University of Oxford. He has held visiting positions at the University of Otago, CEPPA (Centre for Ethics, Philosophy, and Public Affairs) at the University of St Andrews, and at Université de Montréal. Olson works mainly in metaethics, value theory, and history of moral philosophy. He is co-editor with Iwao Hirose of The Oxford Handbook of Value Theory (OUP USA, forthcoming) and he has published several articles in peer-reviewed collections and journals, such as Australasian Journal of Philosophy, Ethical Theory and Moral Practice, Hume Studies, Mind, Oxford Studies in Metaethics, Philosophical Quarterly, Philosophy and Phenomenological esearch, Ratio, and Utilitas.

For the most part, Olson is a lucid writer and it is refreshing to see a philosopher write candidly about the limitations of even his own arguments... the book will likely generate fruitful discussion for years to come. In particular, metaethicists will want to consider Olson's case for moral error theory in chs 5 through 9. Hume scholars might want to consider ch. 2, and those interested in metaepistemology may benefit from reading ch. 8.
