Fred is lost in the desert and dies. Without knowing this, Sally, his loving wife who is a presentist and thinks there is no afterlife spends weeks searching for Fred in the desert, in uncertainty whether Fred is still alive, despite great hardship and danger to her own life.
Observe that a presentist who disbelieves in an afterlife thinks that the dead are simply nonexistent. So Sally is not only uncertain whether Fred is alive, but she is uncertain whether Fred exists. Yet she acts out of love. Hence:
- It is possible to love someone while being unsure whether he exists.
(Of course, one might also think that this case points to there being something defective in believing in presentism or in doubting an afterlife. )
