Vagueness of Free Will

I aim to bring the idea of “degree of free will or freedom” into philosophical debates on free will by rejecting the formulation, ‘we are either free or not’. This idea is based upon my viewpoint of regarding freedom as a realistic phenomena actually occurring. First of all, I focus on the fact that it is vague whether an agent is free or not. This vagueness is interpreted as ontic vagueness, corresponding with the status of freedom as real. However, Evans’s argument regarding ontic vagueness must be considered as, according to his argument, ontic vagueness about identity and objects are impossible. I indicate that this argument assumes the truth-value gap position in borderline cases, hence we can avoid Evans’s argument by adopting truth-value glut position. Of course, the truth-value glut approach has serious difficulties, but I conclude with sketching out a possibility to develop this approach in the free will debate via the introduction of probabilistic valuation.
