 According to this version of naturalism, meaning in life varies from person to person, depending on each one’s variable pro-attitudes. Common instances are views that one’s life is more meaningful, the more one gets what one happens to want strongly, achieves one’s highly ranked goals, or does what one believes to be really important (Trisel 2002; Hooker 2008). One influential subjectivist has recently maintained that the relevant mental state is caring or loving, so that life is meaningful just to the extent that one cares about or loves something (Frankfurt 1988, 80–94, 2004). Another recent proposal is that meaningfulness consists of “an active engagement and affirmation that vivifies the person who has freely created or accepted and now promotes and nurtures the projects of her highest concern” (Belliotti 2019, 183).
