I'd admit that I'm still reading the article, but they are situations and questions that I've ran over and over again myself.
As technology and society progresses, the definition of "socially acceptable" becomes more and more exact, more limited in scope. We can already see the trends towards being politically correct extending to the workplace and home life. It's hard to say if this is a cycle of ebb/flow of freedom within the scope of the socially acceptable. One could argue that the freedoms of the 60/70's expanded the definition from the strict roles of the 40/50's, while today, we seem to be slowly going back to stricter definitions. However, I don't think anybody could really argue that we are less civil than we were 1000 years ago.
Thus, what was considered to be personality traits 1000 years ago are considered social diseases now. As medical knowledge and technology improved, we find better ways to improve these diseases, but at what cost? Who's to say that we'll eventually all be medicated to think like a few select templates? What "Brave New World" would we be entering? But, for now, I'm thinking too long-term.
What about the cure? If one is indeed depressed, would the drug remove traces of "useful depression"? I think the whole argument of the article is whether "useful depression" even exists. Would it be wrong to be depressed and angry at an injustice, and then be motivated to change it? For a un-medicated individual who is truly depressed, the motivation point would probably never come, but for a medicated individual, would the depressed point ever come?
I've thought about finding out ways to change my personality, but I always come up to the question of whether such flaws in my character are considered "socially unacceptable". Are they flaws, or have they passed into the realm of a "disease"? Of course, my personal views do not fall within the scope of human nature, so I cannot say for sure. Maybe I'm trying to find easy ways to correct "socially acceptable" flaws that could be corrected by fixing by changing certain parts of my life.
Would removing such flaws also remove the good-qualities of those flaws? Like the article said, even in somebody who is bi-polar, the manic periods could drive productivity. You try to even out somebody who is bi-polar, and while the work is consistant, the work is not outstanding. Wouldn't that remove periods of inspiration?
Would I be a duller person, if I removed the extremes of my personality? What about my enjoyment of music: is it wrong to feel joy or elation to certain sounds or notes? Would I be less productive because I no longer feel motivated to try challenging tasks or inspired to code?
Honestly, I think the focus of the article was too small. Forget just depression; what about all mental illnesses? After all, with so many people trying to "cure" mental illness, what are we taking away? Taking my example of bi-polarness with his question, should we try to find all sources of bi-polarity and remove the disease like we do with TB or malaria?
The edge between personality and social disease is a very, very thin and ever-changing line. Trying to eraticate a "social disease" could have unpredictable results.
Rosalina: But you didn't.
Robert: But I DON'T.
Rosalina: You sure that's right?
Robert: I was going to HAVE told you they'd come?
Rosalina: No.
Robert: The subjunctive?
Rosalina: That's not the subjunctive.
Robert: I don't think the syntax has been invented yet.
Rosalina: It would have had to have had been.
Robert: Had to have...had...been? That can't be right.
