“Our understanding of the world is largely determined by our ability
to organize information. Where do you live? What do you do? Who are
you? Our answers reveal the systems of classification that form the
very foundations of our understanding. We live in towns within states
within countries. We work in departments in companies in industries.
We are parents, children, and siblings, each an integral part of a
family tree.” p.22
