While many have criticized the current enthusiasm for judging the past by the standards of the present (and condemning those past leaders who did not meet them), few have noted how many currently dominant beliefs are totally disconnected from reality and have a profoundly destructive impact. I propose to discuss two of them here: ideas about the nature of mental illness which have produced what Charles Krauthammer called “an army of broken souls foraging and freezing in the streets” and the conviction that our planet is in existential danger from human-induced climate change. The latter has led to a wholly unwarranted, hugely expensive crusade to eliminate fossil fuels. The chief effect has been to strengthen the leverage of those countries, many of them enemies of the West, that continue to produce these fuels, which remain essential to the functioning of industrial societies.
In the 1960s, a mad idea was born, the notion that there is no such thing as mental illness. Incredibly, it would become the foundation for public policy. The idea sprang independently from two maverick psychiatrists at opposite ideological poles, on the right U.S. psychiatrist Thomas Szasz, an unsparing libertarian, and on the left the British Ronald Laing. Szasz disposed of mental illness by verbal sleight of hand: “Mental illnesses do not exist; indeed they cannot exist because the mind is not a bodily part or bodily organ.” (Never mind that the brain is the bodily organ that malfunctions in mental illness.) Psychiatry is “a form of quackery because it offers cures for which there are no diseases.” Laing treated schizophrenia, the most disabling mental illness, as a “voyage of discovery”; “we find that a person who is labeled insane is often the sanest member of his or her family.”
