QUOTE : new kind of realm was gradually formed. This, the human world, is materially rooted in the natural world but is quite different from it. It is populated by individuals who are not just organisms, as is evident in that they inhabit an acknowledged, shared public sphere, structured and underpinned by an infinity of abstractions, generalizations, customs, practices, norms, laws, institutions, facts, and artefacts unknown to even the most “social” of animals.
