Suppose you could change people's way of thinking about the world at its very roots, by changing the very concepts by means of which they think. Suppose, further, that this would make the world a better place; that would be quite something. Knowledge and Conceptual Engineering is a comprehensive and systematic study of the nature and normativity of conceptual engineering. This book comprehensively deals with all the central questions in the field: the very possibility of conceptua...

Knowledge-first epistemology places knowledge at the normative core of epistemological affairs: on this approach, central epistemic phenomena are to be analyzed in terms of knowledge. This Element offers a defence of an integrated, naturalistic knowledge-first account of justified belief, reasons, evidence and defeat, permissible assertion and action, and the epistemic normativity of practical and theoretical reasoning. On this account, the epistemic is an independent normative domain orga...

We have increasingly sophisticated ways of acquiring and communicating knowledge, but efforts to spread this knowledge often encounter resistance to evidence. The phenomenon of resistance to evidence, while subject to thorough investigation in social psychology, is acutely under-theorised in the philosophical literature. Mona Simion's book is concerned with positive epistemology: it argues that we have epistemic obligations to update and form beliefs on available and undefeated evidence. I...

Shifty Speech and Independent Thought is a manifesto for epistemic independence: the independence of good thinking from practical considerations. Mona Simion defends the independence of thought from the most prominent threat that has surfaced in the last twenty years of epistemological theorizing: the phenomenon of shiftiness of proper assertoric speech with practical context. This study does four things: firstly, it shows that, against orthodoxy, the argument from practical shift...

Assertion is the central vehicle for the sharing of knowledge. Whether knowledge is shared successfully often depends on the quality of assertions: good assertions lead to successful knowledge sharing, while bad ones don't. In Sharing Knowledge, Christoph Kelp and Mona Simion investigate the relation between knowledge sharing and assertion, and develop an account of what it is to assert well. More specifically, they argue that the function of assertion is to share knowledge with others. It...

Traditionally, the notion of defeat has been central to epistemology, practical reasoning, and ethics. Within epistemology, it is standardly assumed that a subject who knows that p, or justifiably believes that p, can lose this knowledge or justified belief by acquiring a so-called 'defeater', whether that is evidence that not-p, evidence that the process that produced her belief is unreliable, or evidence that she has likely misevaluated her own evidence. Within...
