The great achievement of the meritocracy is that it has widened opportunities to those who were formerly oppressed. But diversity is a midpoint, not an endpoint. Just as a mind has to be opened so that it can close on something, an organization has to be diverse so that different perspectives can serve some end. Diversity for its own sake, without a common telos, is infinitely centrifugal, and leads to social fragmentation.
Our missing telos is probably our most fundamental problem. I don’t know how to find telos in a regime where “separation of church and state” makes any idea tainted if it’s acquainted with religion, and where the right of the individual to invent his own telos is enshrined in Supreme Court precedent.
