Possibly THE biggest problem in the world is that people have been taught(yes our educational system contributes to this) to prioritize theory over Reality. So if you look at Ukraine now, the fact is that there is a section of the country(Dombas) that is divided between Russia-leaning and Ukraine-leaning. That is the Reality(somewhat like Northern Ireland which has had its share of difficulties but could be a model for the solution, however).That is the Reality. The theory is about the sovereignty of states and the right of states to join NATO. This can only be perceived as unfair and threatening by Russia! But who cares?! We have theory on our side,right?! At that point, war becomes inevitable. Whenever we prioritize theory over Reality, we get suffering and misery. That is a law of Nature as much as the physics of gravity and momentum.
Another stunning example occurs in medicine- as we can see by the Covid treatment fiasco. The theory is “the randomized, placebo-controlled, large-scale (i.e very expensive) multi-centered study published in a prestigious peer-reviewed journal.” That is the biggest mouthful of theory ever invented lol. The reality is that there were many small-scale studies published in less well-known journals and numerous clinical reports and series from observant, perspicacious doctors that showed that early intervention with cheap ,repurposed drugs could be used to successfully treat Covid and limit hospitalizations and death! That was the Reality! The CDC, the FDA, the NIH, the WHO would hear nothing of it! The consequence was excessive deaths in the hundreds of thousands in the U.S.A and millions worldwide! A significant difference ,no doubt. But who needs Reality when you have a comfortable theory at the bedside?!God help us and protect us from the merchants of Theory, who ultimately are the Merchants of Death!
