““In investigating the lumpings that have shaped societies past and present, we should, I believe, be charitable toward those who merely inherited the classifications that were dominant in their own times. But we should be less patient with those, like Calhoun and Sanger, who pressed to enforce their preferred categories, to encode them in law and make them permanent. Such people are immensely dangerous, and for the health of our public world we need to become alert to the compelling power of lumping: having seen the ways lumping helps us manage information overload and create group solidarity, we should become aware of the temptations it poses to us—to all of us.””
