Defending Bayes

Summary

First in 5-part series defending Bayesian epistemology within QBU against Deutsch/Hall objections. Core argument: Bayes’ theorem rigorously applicable in QBU—Measures (objective quantum probabilities) serve as analogs to classical probabilities; conditional Measures well-defined via Pattern Identifiers. Deutsch/Hall critique: Bayesianism misrepresents science (probabilistic confirmation vs explanatory innovation); credence has no role. Response: Two knowledge categories: (1) Explanatory (scientific theories, non-probabilistic, accepted via criticism), (2) Empirical/predictive (specific facts/outcomes within frameworks, legitimate credence domain). Conclusion: Bayes is “best and only coherent method” for aligning subjective Credence with objective Measure—complements, doesn’t compete with, explanatory knowledge.
