Asymmetry (population Ethics)
The Asymmetry, also known as the Procreation Asymmetry, is the idea in population ethics that there is a moral or evaluative asymmetry between bringing into existence individuals with good or bad lives. It was first discussed by Jan Narveson in 1967, and Jeff McMahan coined the term 'the Asymmetry' in 1981. McMahan formulates the Asymmetry as follows: "while the fact that a person's life would be worse than no life at all ... constitutes a strong moral reason for not bringing him into existence, the fact that a person's life would be worth living provides no (or only a relatively weak) moral reason for bringing him into existence."

Holtug's formulation says that "while it detracts from the value of an outcome to add individuals whose lives are of overall negative value, it does not increase the value of an outcome to add individuals whose lives are o ...

Moral philosopher Derek Parfit brought population ethics to the attention of the academic community as a modern branch of moral philosophy in his seminal work ''Reasons and Persons'' in 1984. Discussions of population ethics are thus a relatively recent development in the history of philosophy. Formulating a satisfactory theory of population ethics is regarded as "notoriously difficult". While scholars have proposed and debated many different population ethical theories, no consensus in the academic community has emerged. Gustaf Arrhenius, Pr ...
