How do you guys think this relates to Cognitive Therapy? What I mean is: My father was a therapist and a big advocate of the idea that people can be happy regardless of their circumstances and that emotion comes primarily from what someone thinks. There's a lot of truth in that, and it seems clear that Cognitive Therapy is an important treatment for depression. However, he sometimes seemed to de-emphasize the importance of circumstances. For example, he was opposed to the idea that moving to a different part of the country could make someone happier. However, doesn't that ignore that fact that different places have different rates of depression and suicide?
