I've long had the idea that the factors that are most important in determining what we believe, how we live, and what we accomplish are matters of accident. That is, we did not choose where to be born, who our parents would be, or what we would look like. Yet those factors play an enormous role in almost everything about is. W/regard to issues of cosmopolitanism, the most obvious point is that how we identify ourselves in terms of nationality, cultural subgroups, and religion are all pretty much a function of where we were born.
