Osherson (Finding Our Fathers), a psychotherapist and self-described "perplexed Jew," tackles the psychology of the "disconnected, discontented and uncounted" Jews whom he says comprise the bulk of American Jewry today. Rather than assuming assimilation means that Judaism is dying, he argues that faith plays a critical role in the process of shaping adult identity—even for those who appear to be far from tradition. Understanding the "undertow"—the childhood-based emotions, conflicts and fears that color attitudes toward religion—can help "build some bridges between the tradition and the discontent," forging both a revitalized community and a stronger sense of self. Osherson urges against measuring Jewish connection by external behavioral markers such as synagogue membership or the ability to read Hebrew, noting instead that many Jews view their Judaism as a "work in progress" that can change with life events like the birth of a child or the death of a parent. Osherson does not rest his case with a psychological discussion; he presents practical solutions for living in an assimilated world and draws his illustrations for finding joy in Judaism from the vibrant lives of real people. Readers may not agree with all of Osherson's assertions—viewing intermarriage as a potential source of strength, for example—but those who follow the thoughtful process he encourages could discover fresh insights for change.
