This chapter discusses the justificationist theory of meaning and then presents the second feature of the metaphysics that follows from this theory: reality is cumulative. It argues that on a justificationist view, there is no legitimate notion of truth for inaccessible propositions other than their having been established as true. It is not merely that few statements about what will hold good at some future time can be established before that time; it is also that other statements may be established long after the time to which they relate, which had not previously been established. The facts that accumulate include ones about what held good before they came to be facts.
