"Some crass optimists attempt to justify procreation in the face of the risks by pointing to the option of suicide. Their argument is that if the person brought into existence finds the quality of his or her life to be unacceptably low there is a way of opting out of existence. These really are shallow words that belie the depth of suffering that precedes and precipitates suicide. The life drive is immensely powerful even when people are enduring unspeakable suffering. This is one reason why suicide is by no means an easy option. Another is that suicide causes great distress to the family and friends of the person who takes his or her own life. . . . One cannot be glib about that."
