Żywot krótki wiele nauk potrzebuje '. Nie straci rozumu, kto go nie ma' . Mądry obiecuje, głupi się raduje.' Miłość o rozum nie pyta'. Mądremu niewiele trzeba mówić.' Mądrej głowy włosy się nie trzymają.' Mądrzy szczęście z sobą noszą.' Mądry nie powie, czego wprzód nie zważy.' Mądry na wszystkie strony się ogląda.' Mądra myszka w łapki nie wpadnie.' Ludzie, nauczając, uczą się. ' Lepszy czasem chłopski rozum bywa niż panskie nauki.' Jaki rozum, taka rada. Ile kto ma cierpliowści, tyle mądrości. ' Im puściej w głowie, tym szumniej w mowie. I mądry głupi, gdy go nędza złupi. I mądry głupieje, gdy pałkę zaleje. Gdzie szczęście panuje, tam rozum szwankuje'. Gdzie rozumu nie masz, tam i rządu. Gdzie rozumu więcej, tam i złość. Gdy włos siwieje, to rozum dojrzeje. .Czego rozum nie może, to często czas leczy'. Co u mądrych w myśli, to u głupich w ustach'. Co rozum, to zdanie. BUCHMANN. KSIĘGA PRZYSŁÓW. Przysłowia są mądrością narodów. Torun, 2009.
I know "Knowledge is power". I also know a more modern one which might be relevant in your case: "when you don't know something, just ask Google" haha.
During the Covid-19 pandemic I have been guided by words of Sir William Osler. Perhaps the greatest physician of modern medicine who ended his career as Professor of Medicine in Oxford.
He who studies medicine without books sails an uncharted sea, but he who studies medicine without patients does not go to sea at all. William Osler
The value of experience is not in seeing much but in seeing wisely.
William Osler
Listen to your patient; He’s telling you the diagnosis.
William Osler
One of the first duties of the physician is to educate the masses not to take medicine. William Osler
Donald Rumsfeld stated: "Reports that say that something hasn't happened are always interesting to me, because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know."
Sir David Brailsford (British Cycling performance director) stated:
“If you broke down everything you could think of that goes into riding a bike, and then improved it by one percent, you will get a significant increase when you put them all together”
This principle can be applied to performance management for almost anything
Re your quote from Donald Rumsfeld, what about unknown unknowns, which is the largest class/type of knowledge. Or do you think that we have milked the universe dry of any of its mysteries?
Donald Rumsfeld stated: Reports that say that something hasn't happened are always interesting to me, because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns — the ones we don't know we don't know. And if one looks throughout the history of our country and other free countries, it is the latter category that tend to be the difficult ones.
"Scientific progress is like an ancient road through the desert - dotted with crumbling skeletons of abandoned theories that seem to live forever when they arise." Arthur Koestler
This is a nice science related aphorism by Galileo : In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.
"There is a presumption of the truth of the view held by many people, and by rejecting it, we should indicate some real or possible reason for his reign..." - John Stuart Mill,
(1) A robot may not injure a human being, or, through inaction, allow a human being to come to harm. (2) A robot must obey the orders given it by human beings except where such orders would conflict with the first law. (3) A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
Aphorisms by theme: Science. Science has not yet taught us if madness is or is not the sublimity of the intelligence. There are no solved problems; there are only problems that are more or less solved. It is through science that we prove, but through intuition that we discover.
"The book is a gentle and sweet sage, empty life fills with light, and empty heart with emotion, love gives wings, and puts pressure on the hardships, introduces life into the dead of home and gives meaning to life." Kornel Makuszyński
"The value of a telephone is what two people have to say to each other." Oscar Wilde
The content of this aphorism has already partially become outdated. Current phones, i.e. mainly smartphones, are already less and less used for conversations while the use of various applications offering various information services available via the Internet is increasing. Dariusz Prokopowicz
"When people bring perfection to each other, they will finally tell each other what they think about themselves, from soul to soul." Stanisław Jerzy Lec
"People are like a river: water is the same in all of them, but a river can be narrow, fast, wide, calm, clean, dark, cloudy, warm. It is the same with people." Lev Tolstoy
The experience of the world does not consist in the quantity of things that have been seen, but in the quantity of things whose reflection has been fruitful.
"The clock only conventionally measures the passage of time that flows according the calendar of The Solar System in which we live and according to the physical processes that occur in it. In other worlds, constellations, planetary systems time can flow quite differently." Dariusz Prokopowicz - ResearchGate (2020, July 18).
