Louis Dupré, a Professor of Philosophy at Yale University, argues that the "spiritual emptiness of our time is a symptom of its religious poverty". He claims that "many people never experience any emptiness: they are too busy to feel much absence of any kind"; they only realize their spiritual emptiness if "painful personal experiences -- the death of a loved one, the collapse of a marriage, the alienation of a child, the failure of a business" shock them into reassessing their sense of meaning.
