Hybrid theories of well-being combine elements of two or more kinds of theory. The most familiar kinds of hybrid combine a subjective requirement (e.g. that a constituent of well-being is enjoyed or desired) with an objective requirement (e.g. that it is also good). This entry discusses a number of such views, but then generalises the discussion in two ways. First, by considering hybrids that combine two or more subjective requirements, or two or more objective requirements, and second, by considering views according to which each component amplifies the value of the other(s), rather than being a necessary condition for the value of the other(s). The upshot is that the category of hybrid theories of well-being is much larger than is usually realised, and contains many views that have not yet been explored.
