This is something I came up with some time ago to summarize a good deal of what
Thomas Szasz, a great libertarian and hero of mine, has been saying for half a century.
If neuroscientists discovered that mass murderers and people who claim to be Jesus had different brain chemistries from other people,
most everyone would accept this as evidence that they suffered from a mental illness/brain
disorder (MI/BD) and that this disorder
caused their behavior.
If neuroscientists discovered that homosexuals had different brain chemistries from heterosexuals,
far fewer people would accept this as evidence that they suffered from a MI/BD and that this disorder
caused their behavior.
If neuroscientists discovered that nuns had different brain chemistries from everyone else,
very few people would accept this as evidence that they suffered from a MI/BD and that this disorder
caused their behavior.
If neuroscientists discovered that married men had different brain chemistries from bachelors,
no one would accept this as evidence that they suffered from a MI/BD and that this disorder
caused their behavior.
Clearly, a difference in brain chemistry
per se is not enough to make people believe that someone has a MI/BD. It takes more. Why, then, would a difference in one case be taken as evidence of MI/BD, while a difference in another case would
not be? The obvious answer is that people, including psychiatrists, are willing to attribute behavior to mental illness/brain disorder to the extent that they disapprove of that behavior, and are
unwilling to do so to the extent they approve of, or at least are willing to tolerate, that behavior. (Psychiatry once held that homosexuality was a mental illness. That position was changed, but not on the basis of scientific findings. Science had nothing to do with the initial position either.)
In other words, the psychiatric worldview rests, not on science or medicine, as its practitioners would have us believe, but on ethics, politics, and religion. That would be objectionable only intellectually if that were as far as it went. Unfortunately, it goes further, since the practitioners and the legal system they helped shape are empowered:
• First, to involuntarily “hospitalize” and drug people “diagnosed” as mentally ill and thought possibly to be dangerous to themselves or others, and
• Second, to excuse certain people of responsibility for their actions (for example, via the insanity defense).
Postscript: I'm often asked which one of Thomas Szasz's two dozen books I'd recommend to someone unfamiliar with his work. I suggest
Insanity: The Idea and Its Consequences. This highly readable book covers most of his views on psychiatry, mental illness, and the Therapeutic State, with responses to his critics along the way. Of course, after that, you'll want to read the rest.
