Abstract

Peter Graham has recently given a dilemma purportedly showing the compatibility of libertarianism about free will and the anti-skeptical epistemology of testimony. In the first part of this paper I criticize his dilemma: the first horn either involves a false premise or makes the dilemma invalid. The second horn relies without argument on an implausible assumption about testimonial knowledge, and even if granted, nothing on this horn shows libertarianism does not entail skepticism about testimonial justification. I then argue for the incompatibility of (i) a view entailed by Open Theism, viz., that there are no true counterfactuals of freedom, (ii) a popular form of process reliabilism about justification and knowledge, and (iii) a weak anti-skepticism about testimonial justification and knowledge. I conclude that there is a costly tension between certain views about testimony and about free will
