Abstrakt: "Unsettled Thoughts: A Theory of Degrees of Rationality" by Julia Staffel is a book that explores the concept of degrees of epistemic rationality within a Bayesian framework. The book aims to clarify and justify the claim that Bayesian principles should be seen as an idealized model of rational belief that humans should strive to approximate. It addresses two main questions: what does it mean for a thinker to be closer to ideal epistemic rationality, and why is it better to be closer to ideal rationality? The book presents various measures of distance between credal states to quantify the degree of irrationality and argues that closer approximation to ideal rationality leads to better action guidance and accurate representation of the world. The book also discusses the limitations of using susceptibility to Dutch books as a proxy for action guidance and the need to incorporate both belief in truth and avoidance of error in a theory of degrees of rationality. Overall, "Unsettled Thoughts" offers valuable insights into formal epistemology and provides a foundation for further research in the field. [Extracted from the article]
