Dear Vladimir,
I enjoyed reading your essay very much. You packed so much useful information into it that I think I could read it a number of times and still find something new to like. At the end of the first part, I had a question to ask you, but I think you answered it in the next part with the Grosseteste quote: "...a sensual knowledge is not a knowledge, but the path to it. Because human knowledge is more likely to occur on the relationship of sensual knowledge with understanding." When I read your paragraph beginning with "In physics, "loss of certainty" also took place gradually, over about a hundred years since the beginning of the study of the phenomenon of electromagnetism, the peak is the theory of relativity with its paradoxes..." (with which I couldn't agree more), I thought I'd ask whether you think (as I do) that the mess we're in (aiming for the highest levels of abstraction, etc.), due to the incompleteness of the Einstein-Planck revolution, has had a lot to do with not caring to make sense of the world.
I mean, when a carpenter sets out to build something, if the first cuts are off, or he doesn't put the pieces together just right, the final product tends to be an ugly mess. I think Einstein went wrong by not attempting to make consistent sense of relativity from the get-go (he clearly demonstrated paradoxical implications, but didn't try to resolve them), so the product was something that makes absolutely no sense (time doesn't pass/no objective distinction between past, present, and future/etc.). I may be wrong, but I thought you'd agree with this because of your reaction to my essay, from the next paragraph you wrote on Galilei's "Assayer", by your quotation from Grosseteste, and finally by your conclusion point 5. I think it's that kind of thinking that brought us out of the dark ages to begin with during the Scientific Revolution, and I think the positivist/verificationist thought in the twentieth century sent us right back there.
Good luck and best wishes,
Daryl
