“The question of begetting is not simply 'to decide whether or not life is worth bringing into existence', but rather, what it means to make that decision on behalf of another person; to decide whether it can be justified to bring a wholly new and unknown life into existence; and whether it is worth the overwhelming risks that existence might involve. It would be an entirely different matter if it were solely our own risk to take; if it were only our own opinion of life we were considering. The reason why begetting is such a tricky question is precisely that we are risking something, everything, on the life of another person. If this is not somehow a problem for us, then what is?”
