I'm currently developing a theory of complex, non-deductive reasoning that does justice to our inferential practices, unifies practical and theoretical reasoning, integrates decision theory, and shows that reasoning is truth-conducive (in one way or another, the books A2-A5 contribute to this effort).
Areas of expertise: reasoning, argumentation theory, general philosophy of science (esp. inference, confirmation, theory change, prediction, science and values, science and democracy), philosophy of climate science, philosophy of economics, social epistemology, applied ethics, Descartes
Areas of interest (non-exclusive): meta-ethics, action theory, pragmatism, formal epistemology, political philosophy, rational hermeneutics
Philosophical theses I've been arguing for include:
- The paradoxes of confirmation can be resolved by factoring in the specific dialectic context within which scientific inferences are drawn.
- Poppers method of corroboration can be veritistically vindicated.
- Doxastic diversity and argumentative criticism enable collective truth approximation (Mill's thesis).
- Discriminating between trustworthy sources according to perceived expertise is not necessarily truth-conducive.
- Scientific policy advice ought to live up the ideal of value free science (pace the argument from inductive risks).
- There exist situations of deep uncertainty where decisions ought to be based on mere possibilistic predictions, which come along with their own methodology (pace decision-theoretic probabilism, EUM, risk analysis and CBA).
In my research, I rely both on informal and formal methods (e.g. computer simulation), and I make extensive use of case studies, especially from economics and climate science, and from policy debates.
I'm also developing argumentation technologies, and am involved in the Argunet Team.
