I’ve been seeing a disturbing tendency among atheists to compare religious belief to mental illness. Sometimes this comparison is made explicit, as in this article. Other times, however, the comparison is more implicit–for instance, when words like “crazy” and “delusional” are used to describe religious people or their beliefs (hi Dawkins).
These comparisons are inaccurate and offensive to both religious people and people with mental illnesses.
First of all, being religious is a choice. Being mentally ill is not. While it’s a bit arguable whether or not faith itself is a choice–I certainly can’t make myself believe in god, but perhaps others can–the existence and success of religious proselytism proves that choice is at least part of the equation. Only a completely ignorant person, on the other hand, would attempt to proselytize mental health (although it obviously does happen).
Regardless of whether or not you can choose to believe in god, you definitely get to choose whether and to what extent you observe a religion (unless you’re a child, but that’s different). People with schizophrenia don’t get to choose which hallucinations they have and how often. People with OCD don’t get to choose their compulsions. People with phobias don’t get to choose which phobias they have or how they manifest themselves.
Second, suggesting that religious people are mentally ill is sanctimonious and offensive. It insinuates that they are incapable of consciously and purposefully choosing to be religious, and that their religious beliefs are just as meaningless as a symptom of mental illness. It reminds me of when I used to bring up concerns with friends who would respond, “Oh, that’s not such a big deal, you just feel that way ’cause you’re depressed.”
As I mentioned, being religious is a choice. For most people, it’s a choice made with one’s own best interests in mind. Comparing that to a schizophrenic delusion is a wee bit condescending.
(Of course, delusions that are religious in nature do exist. Some people with schizophrenia believe that they are possessed by religious spirits of some kind, that they have spoken to god, or that they are the messiah. However, this is vastly different from the way most religious folks experience their faith, and is obviously a symptom of mental illness.)
Although I’m an atheist who kinda sorta wishes religion didn’t exist, the fact is that it does, and I refuse to believe that all of the billions of religious people in the world are just mentally ill. No, they’re onto something. It’s just not something that I’m interested in myself.
Finally, these comparisons trivialize the suffering that people with mental illnesses experience. The distinction between mental health and mental illness is not that mentally healthy people do not believe in supernatural things and mentally ill people do. The difference is that (most) mental illnesses interfere with the person’s functioning and make them feel, well, bad.
Religion, for all its flaws, often does the opposite–it provides people with community, teaches them to behave morally and charitably, and helps them cope with illness, death, and other challenges in life. (A caveat: I’m talking about religion at its best, not at its worst, and these same effects can be found elsewhere.)
So when you imply that the definition of mental illness is believing in things without evidence, you miss a lot about what it’s like to be mentally ill. Namely, you ignore the emotional pain, cognitive distortions, thwarted goals, ruined relationships, physical fatigue, and all the other things that are part of the experience of mental illness.
There are many interesting, intelligent, and non-offensive ways for atheists to argue against destructive religious ideas (for instance, here’s an example I read today). Calling religious people mentally ill is not one of those ways. Let’s put that kind of useless rhetoric back on the shelf where it belongs.
