Bayesianism and Challenges to Confirmation Theory

Bayesians believe that they have solved a significant problem in philosophy of science، which is the identification of the logic which governs evidences. The problem has special importance to philosophy of science، because what eventually distinguishes science from myth is that we have good evidence for the content of science. The core ideas of all versions of Bayesian confirmation theory are that the beliefs are confirmed to a probability measure، and incorporating new evidence is done through conditionalization using Bayes’ rule. Bayesians believe that qualitative approaches to confirmation theory are hopeless; an adequate account of the way evidences support hypotheses and theories must be quantitative، and a quantitative account implicates utilizing the probability calculus. The aim of this paper is to investigate the challenges to confirmation theory by means of the standard Bayesian approach.
