 This position may appear to be open to the regress concerns presented in Galen Strawson’s argument above. But Kane thinks a regress is avoided in cases in which a person’s character-forming choices are undetermined. Since these undetermined choices will have no sufficient causes, there is no relevant prior cause for which the agent must be responsible, so there is no regress problem (Kane 2007: 15–16; see Pereboom 2001: 47–50 for criticism of Kane on this point.)
