A miscellany of other issues in moral philosophy involve the concept of welfare.
The concept of equality is naturally analyzed in terms of welfare: a population
manifests equality to the extent that its members are equally well off. There are
questions about death, such as, Is death bad for the one dies? There are population
puzzles, such as, How many people should there be? One answer is, However many
will maximize total welfare; another is, However many will maximize average welfare.
Applied ethics contains many questions whose answers presuppose views about what
welfare is, such as questions about euthanasia, severely impaired infants, animal rights,
world poverty, and human cloning. Any question in ethics that turns, at least in part, on
questions of benefit and harm, or on what makes life worth living, involves the concept
of welfare.
