" We like to think that we think for ourselves, but it is not that simple. We think like the people we most admire and need. Everyone belongs to a community that reinforces the plausibility of some beliefs and discourages others. Berger notes that many have concluded from this fact that, because we are all locked into our historical and cultural locations, it is impossible to judge the rightness or wrongness of competing beliefs. "
