 Some theorists say that posthumous harm occurs when posthumous events change the value of a person’s life for the worse. Dorothy Grover (1989) suggests that posthumous events may affect the “quality” of a person's life, say by changing the value of her accomplishments. David Velleman (1991) argues along similar lines, claiming that later events may affect the meaning of earlier events, and the latter bears on the value of a person’s life.
