When critics of modernity say that we should stop classifying, they themselves are classifying. I heard one postmodern preacher say that we should stop putting things in boxes – that is classifying things as christian, secular, etc. But in doing so, he himself is classifying people.
It is in man’s nature to organize and classify. Taxonomy is in man’s very nature. Look at what postmodern’s do when they enter into the folksonomic activities. They are classifying.
Theologically, God’s first command to man was to name all of the animals He has created. Here man classifies and provides names for the animals. It is part of discovery. We find something, then we name it.
