 To illustrate MacCallum’s point, let us return to the example of the smoker driving to the tobacconists. In describing this person as either free or unfree, we shall be making assumptions about each of MacCallum’s three variables. If we say that the driver is free, what we shall probably mean is that an agent, consisting in the driver’s empirical self, is free from external (physical or legal) obstacles to do whatever he or she might want to do. If, on the other hand, we say that the driver is unfree, what we shall probably mean is that an agent, consisting in a higher or rational self, is made unfree by internal, psychological constraints to carry out some rational, authentic or virtuous plan. Notice that in both claims there is a negative element and a positive element: each claim about freedom assumes both that freedom is freedom from something (i.e., preventing conditions) and that it is freedom to do or become something. The dichotomy between ‘freedom from’ and ‘freedom to’ is therefore a false one, and it is misleading to say that those who see the driver as free employ a negative concept and those who see the driver as unfree employ a positive one. What these two camps differ over is the way in which one should interpret each of the three variables in the triadic freedom-relation. More precisely, we can see that what they differ over is the extension to be assigned to each of the variables.
