us + them | binary oppositions

It is a feature of culture that binary oppositions come to seem 'natural' to members of a culture. Many pairings of concepts (such as male-female and mind-body) are familiar within a culture and may seem commonsensical distinctions for everyday communicational purposes even if they may be regarded as 'false dichotomies' in critical contexts.

Rudyard Kipling satarised the apparently universal tendency to divide the people we know directly or indirectly as us and them. 

All nice people, like us are We

And everyone else is They:

But if you cross over the sea, 

Instead of over the way

You may end by (think of it)

Looking on We

As only a sort of They!

Rudyard Kipling

'We are They'
