You and I are members of a culture. Likely we are members of different cultures. Mine—one of mine, anyway—is South by Southwestern folded up into a Jesuitical Irishness tempered with first-generation punk rock. Yours may be Puritan, or Huguenot, or heavy metal. Whatever it is, it holds deep meaning—for culture, in the classic anthropological definition, is the sum of a set of beliefs and practices that go into making you and me part of the world, and sometimes very different worlds.
