For example, a public servant who is passionate about his work may experience a great deal of positive emotion and meaning over the course of his career, but his relationships may suffer if he over- works. A selfless Mother-Theresa type may have meaning, accomplishment and fulfilling relationships, but experience little joy. These examples point to a third concern: it is not clear whether Seligman’s conceptualization of well-being is shared among cultures. Third, there is no empirical evidence that constructs such as meaning or love can be measured more objectively than happiness. If happiness is “all in one’s head”, as Seligman asserts, then so are some of the four pillars. Terms such as flourishing and well-being are useful shorthand, but calling the four pillars a theory is premature. Size Matters: Second Growth Forest (2008) by Eamon MacMahon.
