Given the unfortunate (but arguably necessary) divorce of psychology from philosophy more than a century ago, books like Meaning in Life and Why It Matters, which allow for dialogue between these disciplines, are a much-needed and much-welcomed development. . . . Wolf's essay is a psychologically sophisticated philosophical argument on the structure, reality, and importance of meaningfulness in life. Its psychological sophistication lies not in her mastery of any particular empirical literature but rather in her attentiveness to normal, everyday intuitions and feelings. --Russell D.
