The author of “The Defeated Mind” is the famous Spanish writer, philosopher and psychologist José Antonio Marina, winner of many prestigious awards, including the National Prize for the best popular science book. All his works are dedicated to man - his strengths and weaknesses, opportunities and place in society. For Marina, the study of the human mind is the key to understanding a whole range of problems that individuals face in the modern world. What mistakes does our mind most often make? Why do we sometimes behave downright stupidly? If there is a scientific theory of mind, then stupidity deserves no less deep study. The word “stupidity” has not become a scientific term; the word too often turns into an insult. According to Marina, if the science of stupidity were taught in schools and universities, it would bring enormous social benefit. After all, stupidity is the disease of our time, and it is extremely contagious. Marina examines the most effective methods of combating stupidity and provides a number of specific tips that will allow, if not completely defeat this eternal enemy of humanity, then, in any case, successfully resist it.* * *There are smart and stupid people, smart and stupid families, smart and stupid societies. Why, in some circumstances, even a person with a highly developed intellect behaves inexplicably stupid? Why does the mind not always manage to control our behavior and we make cruel mistakes? These and many other questions are answered in “The Defeated Mind” by the famous Spanish philosopher, psychologist and writer H.A. Marina.
