“Time softens all griefs, they say, and it is useless to dwell on lives that might have been. We are granted only one life, and one is enough. Whom do such regrets profit? What do they achieve, except to bring us unhappiness?”

“I don't have any regrets, really, except that one. I wanted to write about you, about us, really. Do you know what I mean? I wanted to write about everything, the life we're having and the lives we might have had. I wanted to write about all the ways we might have died.”

“Hell begins on the day when God grants us a clear vision of all that we might have achieved, of all the gifts which we have wasted, of all that we might have done which we did not do”

“Einmal ist keinmal, says Tomas to himself. What happens but once, says the German adage, might as well not have happened at all. If we have only one life to live, we might as well not have lived at all.”

“Bringing people into existence as well as failing to bring people into existence can be regretted. However, only bringing people into existence can be regretted for the sake of the person whose existence was contingent on our decision. This is not because those who are not brought into existence are indeterminate. Instead it is because they never exist. We can regret, for the sake of an indeterminate but existent person that a benefit was not bestowed on him or her, but we cannot regret, for the sake of somebody who never exists and thus cannot thereby be deprived, a good that this never existent person never experiences. One might grieve about not having had children, but not because the children that one could have had have been deprived of existence. Remorse about not having children is remorse for ourselves—sorrow about having missed childbearing and child-rearing experiences. However, we do regret having brought into existence a child with an unhappy life, and we regret it for the child’s sake, even if also for our own sakes. The reason why we do not lament our failure to bring somebody into existence is because absent pleasures are not bad.”

“Hell is the day when God grants us a clear vision of all that we might have achieved, of all the gifts which we have wasted, of all that we might have done which we did not do...For me that conception of hell lies in two words: Too late!”
