Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

Can quite different values be rationally weighed against one another? Can the value of one thing always be ranked as greater than, equal to, or less than the value of something else? If the answer to these questions is no, then in what areas do we find commensurability and comparability unavailable? And what are the implications for moral and legal decision making? This book struggles with these questions, and arrives at distinctly different answers.".

Benatar argues that it is better never to have been born because of the harms always associated with human existence. Non-existence entails no harm, along with no experience of the absence of any benefits that existence might offer. Therefore, he maintains that procreation is morally irresponsible, along with the use of reproductive technology to have children. Women should seek termination if they become pregnant and it would be better for potential future generations if humans become extinct as soon as humanely (...) possible. These views are challenged by the argument that while decisions not to procreate may be rational on the grounds of the harm that might occur, it may equally rational to gamble under certain circumstances that future children would be better-off experiencing the harms and benefits of life rather than never having the opportunity of experiencing anything. To the degree that Benatar’s arguments preclude the potential rationality of any such gamble, their moral relevance to concrete issues concerning human reproduction is weakened. However, he is right to emphasise the importance of foreseen harm when decisions are made to attempt to have children. (shrink)
