the riddle of society 

From pg 165 of Margaret Archer’s Realist Social Theory:

What is it that depends on human intentionality but never conforms to anyone’s intentions? 

What is it that relies upon people’s concepts but which they never fully know? 

What is it that depends upon human activity but never corresponds to the actions of even the most powerful? 

What is it that has no form without us, yet which forms us as we seek its transformation? 

What is it that never satisfies the precise designs of anyone yet because of this always motivates its reconstitution?
