I don’t believe in mental illness, per se, even though it’s a common diagnosis in my family. Sometimes symptoms are caused by character or spiritual problems; often by physical or chemical problems. But it’s a mistake to consider it a disease that some people (i.e. other people) have. I see it as an extreme version of problems that all of us have. All of us can be irrational at times. Most of us can control it. But none of us think clearly or feel accurately all the time. We are mistaken if we take our own minds too seriously. Insanity is more common in ourselves than we think, and less common in others than we suppose.
