Robin: Archaeologists can study the artifacts left by ancient cultures to determine whether they were nomadic or sedentary.
Robin's 1st Claim
Archaeologists can study the artifacts left by ancient cultures to determine whether they were nomadic or sedentary. Is K saying that archaeologists can't derive whether a culture was nomadic or sedentary by its artifacts?
Yes, it does seem like Kendall is pushing back on this idea. He's saying that the artifacts a culture used were a function of availability, not of lifestyle (nomadic vs. sedentary).
Robin's 2nd Claim
If artifacts were made to last, rather than to be quickly discarded, then the culture was likely sedentary. Is K saying that finding durable artifacts doesn't mean that the culture was probably sedentary?
Hmm, not quite? It feels more like Kendall would disagree with an opposite version of that. He would say if durable, probably sedentary" but think that "if discardable, probably nomadic" is too much of a leap.
Goal
Fundamentally, they're arguing about whether you can / can't derive a pretty solid inference about nomadic vs. sedentary lifestyle based on the artifacts left behind by a culture.
