A culture can be destroyed without taking out civilization though. It happens all of the time. Comparing it to a foundation is absolutely terrible.
You're objecting to my use of the word foundation for some reason and all I'm getting out of it is why even bother.
But here goes anyway as you may have heard words have multiple meanings and not everyone uses them the same way.
I'm referring to the second meaning of foundation: an underlying basis or principle.
Culture -> society -> civilization
These three things are built on each other.
When one changes all the others are affected without necessarily being destroyed but yes if one is destroyed the others will suffer too.
You're also probably referring to an alternate definition of civilization as in all of humanity whereas if you ask Siri the definition of civilization is literally what I've written so like why all the hate bub?
"The society, culture and way of life in a particular area" i.e inside a corporation.
Mess with the culture and it has outward ripples to the entire way of life duh
You can’t have culture without a society and culture is heavily impacted by civilization as well.
“Culture -> society -> civilization” is too rudimentary to be useful and it’s just plain wrong in many cases. Changes in technology (e.g. smartphones) or massive events (e.g. pandemics) flow backwards through the chain eventually forcing the culture to change to adapt (social distancing, etiquette for texting at the table, etc).
