Publications

He published two books of philosophical studies through the Muirhead Library of Philosophy: "Enigmas of Agency," Allen & Unwin, London, 1972, and "Perception, Emotion & Action," Blackwells, Oxford, 1977.

Unlike most epistemologists, Thalberg published articles that defended the Platonic tripartite analysis of knowledge (justified true belief, a.k.a. "JTB") against the more popular view that Gettier counterexamples refuted the JTB account. Specifically, Thalberg argued that justification is not transmissible through valid deduction.
