Some of the topics that come under the heading of formal epistemology include:
- Ampliative inference (including inductive logic);
- Game theory and decision theory;
- Algorithmic learning theory (computational epistemology);
- Formal theories of coherence;
- Foundations of probability and statistics;
- Formal approaches to paradoxes of belief and/or action.
Though formally oriented epistemologists have been laboring since the emergence of formal logic (if not earlier), only recently have they been organized under a common disciplinary title. This gain in popularity may be attributed to the organization of yearly Formal Epistemology Workshops by Branden Fitelson and Sahotra Sarkar, starting in 2004, and the recent PHILOG-conferences starting in 2002 (The Network for Philosophical Logic and Its Applications) organized by Vincent F. Hendricks.
