Marcuse It seems Here's work is slightly controversial, so I'm not sure how much merit it has.
Sure thing. I'm not sure that it's really useful to obsess over the correct use of terminology in this case though. Determining whether this or that specific problem is caused by nature or nurture is a different question than "how are people born with such and such an illness" and we really don't need to know the specific problem, so I'm okay using a largely intuitive interpretation of the terminology where we don't need to know the specifics of the problem.
That's probably because my position on nature/nurture is that the answer is "both". I see it like categorising people like this:
Nature: Upper case letter
Nurture: lower case letter
So the first person(ality type) on my list would be Aa, and a person who was Ba would have a different underlying personality but similar upbringing. Of course that's still a massive oversimplification, but it makes more sense to me that we view people as starting from a particular point and then influenced further by other things, which can make them act in certain ways. Someone who's not inclined towards a certain behaviour can be directed towards it by experience (whether that's negative like abuse, or positive like training) and someone who is inclined towards a behaviour can be directed away from it by experience.
