Unbelievable Errors defends an error theory about all normative judgements: not just moral judgements, but also judgements about reasons for action, judgements about reasons for belief, and instrumental normative judgements. This theory states that normative judgements are beliefs that ascribe normative properties, but that normative properties do not exist. It therefore entails that all normative judgements are false. Bart Streumer also argues, however, that we cannot believe this error theory. This may seem to be a problem for the theory. But he argues that it makes this error theory more likely to be true, since it undermines objections to the theory and it makes it harder to reject the arguments for the theory. He then sketches how certain other philosophical theories can be defended in a similar way. He concludes that to make philosophical progress, we need to make a sharp distinction between a theory's truth and our ability to believe it.

In Unbelievable Errors, Bart Streumer defends an error theory about all normative judgements: not just moral judgements, but also judgements about reasons for action, judgements about reasons for belief, and instrumental normative judgements. This theory says that these judgements are beliefs that ascribe normative properties, but that these properties do not exist. It therefore entails that all normative judgements are false. Streumer also argues, however, that we cannot believe this error theory. This may seem to be a problem for the theory, but he argues that it is not. Instead, he argues, our inability to believe this error theory makes the theory more likely to be true, since it undermines objections to the theory, it makes it harder to reject the arguments for the theory, and it undermines revisionary alternatives to the theory. Streumer then sketches how certain other philosophical views can be defended in a similar way, and how philosophers should modify their method if there can be true theories that we cannot believe. He concludes that to make philosophical progress, we should sharply distinguish the truth of a theory from our ability to believe it

Jonas Olson presents a critical survey of moral error theory, the view that there are no moral facts and so all moral claims are false. Part I explores the historical context of the debate; Part II assesses J. L. Mackie's famous arguments; Part III defends error theory against challenges and considers its implications for our moral thinking.

The author, a computer science professor diagnosed with terminal cancer, explores his life, the lessons that he has learned, how he has worked to achieve his childhood dreams, and the effect of his diagnosis on him and his family.

This edited volume advances the new subdiscipline of metaepistemology by drawing on the sophisticated frameworks that have been developed in metaethics concerning practical normativity. Chapters examine whether these theories can be applied to epistemic normativity and consider what this may tell us about both epistemic and practical normaitivity.

Current academic philosophy is being challenged from several angles. Subdisciplinary specialisations often make it challenging to articulate philosophy’s relevance for the societal questions of our day.Additionally, the success of the ‘scientific method’ puts pressure on philosophers to articulate their methods and specify how these can be successful. How does philosophical progress come about? What can philosophy contribute to our understanding of today’s world? Moreover, can it also contribute to resolving urgent societal challenges, such as anthropogenic climate change? This edited volume evaluates the place of philosophy in the age of science. It addresses three related sub-themes: philosophical progress, philosophical method and philosophy’s societal relevance. Fourteen authors engage with these sub-themes, focusing on the topics of their philosophical expertise, such as the philosophy of religion, evolutionary ethics and the nature of free will. In doing so, they explore their methods of enquiry, and look at how progress in their research comes about.

Oxford Studies in Metaethics is the only publication devoted exclusively to original philosophical work in the foundations of ethics. It provides an annual selection of much of the best new scholarship being done in the field. Its broad purview includes work being done at the intersections of ethical theory with metaphysics, epistemology, philosophy of language, and philosophy of mind. The essays included in the series provide an excellent basis for understanding recent developments in the field; those who would like to acquaint themselves with the current state of play in metaethics would do well to start here.
