The Dogma of Science
Greer has written often how the Establishment in the various fields of Science have been co-opped by financial concerns of corporate money and grants. Industrial money buys results to say what advertising departments want, no matter what the research says. In addition, government regulators have been bought off with the revolving door of corporate lobbyist jobs. So instead of cheap no longer under patent medicinal cures being recommended, we must all take the latest questionable chemical vaccines that just coincidentally make pharmaceutical companies trillions.
One thing not mentioned as well, is the dogma of established scientific "Truth™". Reputations within the education, medical and scientific community are made or broken by the research papers which are allowed to be published. If you do research which contradicts the accepted beliefs, or do a study which casts doubt on the recommendations of famous people within science, the Powers which control what is told to the public will squash you like a bug.
Even if this act causes public harm or death.
This article (long but a good read anyway) talks about one such instance at the start of the recent Pandemic.
"The 60-Year-Old Scientific Screwup That Helped Covid Kill - All pandemic long, scientists brawled over how the virus spreads. Droplets! No, aerosols! At the heart of the fight was a teensy error with huge consequences.
There will be more illnesses in the Long Descent, some merely inconvenient, some lethal and dangerous. We need to be informed and able to understand how to protect ourselves despite the dogma of science and what we're being told by people with agendas.
