In this chapter an exposition of Wiggins’s distinctive account of personal identity is presented. His ‘Human Being Theory’ is interpreted by some as ‘neo-Lockean’ and as ‘animalist’, but these readings will be resisted. According to his account, we are fundamentally both persons and human beings. To substantiate this reading, three interlocking arguments are drawn out: the Strawsonian argument, the Semantic Argument, and the Argument from Interpretation.
