Interventionist Explanation and the Problem of Single Variable Boundary Constraints

According to Interventionism , explanations cite invariant relations which hold among multiple variables. Interventionism incorrectly implies, however, that many common scientific explanations—which cite single-variable boundary constraints—are not actually explanatory. So I propose a different account of explanation, similar in spirit to Interventionism , which gets those cases of scientific explanation right.     

Libertarianism,the Rollback Argument,and the Objective Probability of Free Choices

It is widely assumed that candidates for free, undetermined choices must have objective probabilities prior to their performance. Indeed although this premise figures prominently in a widely discussed argument against libertarianism, few libertarians have called it into question. In this article, I will investigate whether libertarians ought to reject it. I will conclude that doing so should not be tempting to event‐causal libertarians or most agent‐causal ones, because the added costs outweigh the benefits.
