 This kind of objectivity does not make probability a feature of the world or a theoretical construct based on facts of nature. Such stronger forms of objectivity underlie, for instance, a true proto-frequentist understanding of  probability.[43]  If probability means “what frequently happens”, probability will often derive from objective features of the world. If frequent occurrence of x is only an indicator for the affirmability of sentences about x, medieval proto-frequentist probability is not strongly objective in this way. Nevertheless, at least the medieval semantic notion of probability seems to be objective in the strong sense. A proposition, the predicate of which mostly inheres in its subject, is at least in some cases objectively probable on ontological grounds from a scholastic point of view. Facts of nature determine the degree to which predicates inhere in a subject, so that it becomes objectively probable that a mother loves her child.
