[I]n the post-modern world, when identity can be merely symbolic and momentary, identity becomes a poor substitute for lived experience, for practice. Measuring people’s feelings might have been an important corrective for sociologists whose survey instruments measured identity purely in relation to ritual practices and friendship patterns. But people’s feelings do not get us very far. The vast majority of North American Jews have positive feelings about their Jewishness. But that does not mean that Jewishness plays an important or even meaningful role in their lives.
