Question

Specifically why is the structural significance of liminality important, and why is liminality important? TIA

Answer 1

When everything is normal in society, we are operating according to the rules of our established social structure.

When something changes and society enters a state of uncertainty, anything can happen because the rules don't necessarily apply anymore.  

This uncertain state is liminality and, because anything can happen, it is a state of anti-structure.  The old rules may not apply and, even when they might, their application may seem arbitrary and might not work well.

Anti-structure is rectified when society passes through a process of negotiation or re-education that somehow brings the actual state of society in line with the values/rules that are operating by allowing people to invent new ways of doing things that meet the new needs of a society.

So the structural significance of liminality lays in the human potential to change cultures profoundly and rapidly when uncertainty or instability arises in the cultural system.
