Evidence seminars. These tend to focus on the epistemology and methodology of current science, mathematics and medicine. These normally take place weekly. Please contact Jon Williamson if you would like to attend.

This workshop will explore practical consequences of recent philosophical work on health. Talks will be accessible to the general public. The workshop is organised by the Health Methodology Group of the Centre for Reasoning at the University of Kent. This group works on the foundations of evidence-based medicine and values-based healthcare, as well as concepts of health and disease and problems to do with medicine and the law.

Jon Williamson, Kent
This symposium will provide a gentle introduction to inductive logic, including the Carnapian tradition and Bayesian approaches. We will outline some recent developments in the Carnapian tradition and explore in some depth an exciting new challenge for the Bayesian approaches: the entropy limit conjecture.
5 February 2019: Symposium on Health Methodology, University of Kent, 3-5.30pm, Room TBC. To attend please contact Jon Williamson.
Daniel Auker-Howlett: “Evaluating Evaluating evidence of mechanisms in medicine”
David Corfield: “How to understand ‘placebo’ and ‘psychosomatic'”
Virginia Ghiara: “New quality assessment tools for the NHS”
Michael Wilde: “Mechanistic evidence in medical consensus conferences”
This symposium will explore present some new work of the Health Methodology Group of the Centre for Reasoning at the University of Kent. This group works on the foundations of evidence-based medicine and values-based healthcare, as well as concepts of health and disease and problems to do with medicine and the law.

In order to better understand some phenomenon, a scientist will sometimes build a model of the phenomenon. For example, to better understand some biomedical phenomenon, a scientist might try to build a model of the mechanism responsible for the phenomenon. Some philosophers also build models. For example, some epistemologists have appealed to formal models in an attempt to understand the nature of rational degrees of belief. How is this model-building activity supposed to aid understanding, given that the models are often highly idealized? And is this model-building activity even legitimate in philosophy? In this symposium, a group of philosophers will try to answer these questions by discussing the role of models in science and philosophy.

24 March 2017: Symposium on the Principal Principle, GS8, University of Kent, 2-4pm.
Jon Williamson (University of Kent): The principal principle implies the principle of indifference
Christian Wallmann (University of Kent): On the unviability of the principal principle
Richard Pettigrew (University of Bristol): The principal principle does not imply the principle of indifference
Background. Recently, Hawthorne, Landes, Wallmann and Williamson argued in a joint paper that the principal principle implies the principle of indifference. Jon Williamson will present and defend their alrgument. Richard Pettigrew argues that 1) Hawthorne et al’s argument does not apply to Levi’s principal principle and that 2) Hawthorne et al’s argument presupposes the principle of indifference and is therefore circular. Christian Wallmann argues that the principal principle is itself unviable and that therefore Hawthorne et al’s argument does not support the principle of indifference.
20 March 2017: Symposium on objective Bayesianism, KS1, University of Kent, 3-5pm.
Fabrizio Leisen (University of Kent, Statistics)
Cristiano Villa (University of Kent, Statistics)
Jon Williamson (University of Kent, Philosophy)
Background. This interdisciplinary symposium is dedicated to objective Bayesianism—the thesis that in absence of any information there are still rational constraints on prior probability distributions. The symposium introduces objective Bayesianism and discusses its philosophical and statistical foundations. It then examines a particular prior distribution that is supposed to satisfy the tenets of objective Bayesianism. Finally, this prior is applied to a skewed t-model and an important invariance property is established within this model.
