ABSTRACT
Substance dualism (dualism, for short) is the view that a human being is a soul (mind)- body composite. For the sake of simplicity and clarity, I will assume that the soul is the person. In the words of C. S. Lewis, “A soul is that which can say I am” (Lewis 2004: 409). Libertarianism is the position that a person is free, at least on some occasions, to make ultimate and irreducible undetermined choices for reasons (purposes).
