According to a second theorist, Peter van Inwagen, while a life is indeed an event, it is not the history of something. “‘Russell’s life,’” van Inwagen writes (1990, p. 83), “denotes a purely biological event, an event which took place entirely inside Russell’s skin and which went on for ninety-seven years.” Russell’s life included the oxygenation of his hemoglobin molecules but not the publication of his books.
