it has been used to try to clarify the relationship between
theory and evidence. Many insights in the philosophy of science
involving confirmation, falsification, the relation between
science and pseudosience, and other topics can be made more
precise, and sometimes extended or corrected, by using Bayes’
Theorem. These pages will introduce the theorem and its use in
the philosophy of science. Begin by having a look at the
theorem, displayed below. Then we’ll look at the notation and
terminology involved. n this formula, T stands f
