Teams and roles for Nick Shackel
Emeritus Professor
Overview
Central questions in philosophy are concerned with rationality and with paradoxes. I like to work in both these areas.
I have worked extensively on the nature of the obligation to be rational in action and belief. Moral, cultural, political and religious commitments give rise to a highly diverse variety of apparent obligations about what to do and believe. My work in this area is directed at analysing how rationality's authority relates to these obligations.
My work on paradoxes has taken me into working on their manifestations in formal theories of rationality, in epistemolgy and in metaphysics.

Research
Research interests
Rationality and the relation of rationality and normativity. My work here includes practical reason and also the relation of rational belief and the ethics of belief.
The application of formal methods to philosophical questions. My work here includes papers on metaphysics, epistemology and paradox.
Biography
I did my doctorate at the University of Nottingham, giving a Humean answer to the question of why we ought to be rational. I have lectured at the Universities of Nottingham, Warwick and Aberdeen and immediately prior to taking up my position at Cardiff was a research fellow in the faculty of philosophy at Oxford.
Supervisions
I am interested in supervising research in the following areas:
Rationality and the normativity of rationality.
Formal theories of rationality and epistemology.
Formal methods and problems in metaphysics.
Paradoxes.
