Do we need an alternative ‘relational approach’ to saviour siblings?

Michelle Taylor-Sands rejects the argument ‘commonly used to justify selective reproduction, that it is better to be born than not’. The supposed inadequacy of this position is one of the things that pushes her towards an alternative ‘relational’ approach. Here, I consider briefly her three main objections: 1. The Non-Identity Problem does not apply to all the risks associated with the preimplantation genetic diagnosis (PGD) process. 2. The ‘life not worth living’ standard applied in wrongful life cases is not suitable for selective reproduction. 3. The reasoning described above has ‘morally objectionable’ implications.
