||The topic of well-being (welfare, self-interest, the good life) concerns how well an individual is doing or faring and, more broadly, how well one's life goes for her. Things that positively impact your well-being are good for you, benefit you, are in your self-interest, or have prudential value for you; things that negatively impact your well-being are bad for you, harm you, or have prudential disvalue for you. The philosophical literature on well-being is primarily devoted to assessing theories of well-being, which purport to identify what ultimately makes us better or worse off. The distinction between subjective and objective theories marks a notable divide in the literature. Proponents of subjective theories--e.g. desire-fulfillment and, arguably, hedonistic theories--maintain that something is good (or bad) for you only if you have, or under idealized conditions would have, some specified favorable (or unfavorable) attitude toward it. Proponents of objective theories, such as objective list and perfectionist theories, deny this.
