On the advantages and disadvantages of science and technology

The development of science and technology has brought a lot of convenience and troubles to our people's lives. We should correctly understand the advantages and disadvantages brought by science and technology. Learn from me the composition of advantages and disadvantages of science and technology!

1 advantages and disadvantages of science and technology

Have you ever thought that technology makes people numb and cold-blooded, makes people disrespect everything, and makes people think that they are the masters of the world? In fact, this film also tells us that human beings have conquered the natural society, but they don't respect it. If human beings don't even respect technology and destroy the human society they created, then we "can't be replaced by other species", because nature will follow the biological law of survival of the fittest and re-choose its master. The question is how to avoid it. Dong Zeng wrote in "On Contradiction" that "rationality is reliable because it comes from sensibility", which clearly tells us that people's attitude towards science and technology should take rationality as the standard and sensibility as the principle, so that science and technology can truly serve people, instead of making science and technology the master of people and making people an accessory of science and technology and a part of machines. In fact, it lies in people, how to make good use of sensibility as a mediator of reason.

In the Enlightenment era, there was the Enlightenment (1early 8th century 1798), which brought benefits to people. Together with the rationalism movement, it promoted people's ideological progress and completely broke away from religious superstition. During this period, there was an enlightenment in culture and earth-shaking changes in industry. However, the production progress of large industries has also brought disadvantages to people. His parents will say how naive and romantic it is for you to go to the Origin of Species. His parents can completely lie to his children and tell them the truth, which will not help him, but will destroy his creativity. Therefore, excessive rationality itself is unscientific, because there must be contradictions in things, and the relationship between rationality and sensibility must be unity of opposites.

Contemporary political science research includes perceptual political philosophy and rational political science. Since19th century, political science has started a scientific process. Especially after 1950s, influenced by "behaviorism", scientific politics became a fashion of political research, which paid attention to the precision and quantification of research forms and means, so it paid attention to quantitative research and abandoned qualitative research. Excessive rationality regards politics as statistics of numbers, and the result is the same. What is submerged in the long river of history and does not promote social development will naturally be eliminated.

On the advantages and disadvantages of science and technology II

Faraday, Darwin, Mendel, Bian Que and Li Shizhen all devoted their lives to science. The opposing debater has always stressed that the disadvantages outweigh the advantages. If the disadvantages outweigh the advantages, why should adults let them learn from these scientists?

You are wrong. Our days today are all earned by hard-working scientists with their wisdom and even their lives. Because of Faraday, our life is full of all kinds of electrical appliances; Because of Darwin, because of Mendel, we can know ourselves better and know ourselves; Because of Bian Que, because of Hua Tuo and because of Li Shizhen, our lives can be guaranteed. Didn't they buy everything around us? Life is so comfortable, life is so pleasant and life is so wonderful. Our average life expectancy is 30 years higher than that in ancient times, and we don't even have to go out to visit relatives and friends. Isn't this all the benefits of scientific development?

Don't argue with another debater. Technology has changed history. We don't need to question whether the development of science and technology is beneficial or harmful, because it is beneficial! Without the development of science and technology, our life would be unimaginable, and our days would be dark. It was the development of science and technology that saved us, and it was science that saved us from the fiery age of water. We should respect him with awe. How can we say that the development of science and technology is full of drawbacks?

Friends of the debate, you always list the disadvantages of technology. The development of science and technology seems to have only brought disaster to mankind. Then why do we still emphasize that science and technology are the primary productive forces? Why should mankind continue to develop science and technology?

You say that it is wrong for human beings to insist on developing science? From the medical point of view: the emergence of various modern technologies and laser surgery has saved many people's lives; Astronomy: the invention of artificial earth satellites and spacecraft, such as meteorological satellites, can accurately predict future weather changes and provide convenience for human production and life; In terms of human life, various electrical appliances make people's lives very comfortable, such as air conditioning, which is warm in winter and cool in summer. How can you say that human beings are wrong?

Without technology, we might still be in primitive society, so what's the use of the environment?

Now people are protecting the environment while learning science and technology. How can it be said that learning science and technology will definitely destroy the environment?

This does not mean that the disadvantages outweigh the advantages. This is only an individual phenomenon, but they do not use science and technology correctly, which does not deny the benefits that science and technology bring to mankind.

You said that the development of science and technology brought air pollution, you said that the development of science and technology produced white garbage, and you said that the development of science and technology caused the warming of the temperature. Everything can't be perfect. The brighter the place, the darker the shadow behind it. But on this basis, you can come to the conclusion that the disadvantages of scientific and technological development outweigh the advantages? Different times lead to different problems. Except air pollution, all provinces and cities have put forward prevention plans. White garbage, unified treatment; Automobile exhaust causes the temperature to warm, and scientists have also developed solar-powered cars. Look at now, solar water heaters, solar air conditioners and solar cells have gradually entered thousands of households. Isn't this the development of technology?

Although there are disadvantages, it is irrelevant compared with the scientific and technological development concept of benefiting mankind and protecting home. As long as there are drawbacks, scientists will try to solve them. We can't stop eating because of choking, and the pace of scientific and technological development will not stop for a moment. There is nothing wrong with the development of science and technology, that is, to benefit greatly. This is the only answer to this argument! Just because science and technology have been advancing and science has been developing, cunning sophistry, generalization and unreasonable entanglement can't change this truth. If you say that the development of science and technology does more harm than good, can you come to class without a car, gel pen, ballpoint pen and pen within a week? Can you stop watching TV, listening to the news, reading newspapers, reading books and surfing the Internet for a week? Can the developed hybrid rice not be eaten for a week? No spaghetti? Don't drink? I can't.

No, science and technology is a weapon for human beings to overcome and transform nature and an important force to promote the development of social productive forces. Every development of science and technology is a leap in the history of human civilization and an epoch-making victory for human beings to conquer nature and self. In the early days of primitive society and slave society, it was precisely because of the casting of bronzes and the use of ironware that social wealth doubled and caused changes in social form. In the industrial revolution in the18th century, it was precisely because of the wide application of steam engine technology that the industrial revolution entered a new stage, thus doubling the wealth of the capitalist world. After the Second World War, it was precisely because of the influence of the third scientific and technological revolution, which mainly focused on electrical appliances, that it greatly promoted the economic recovery of post-war capitalist countries and the substantial economic growth of socialist countries, and promoted the rapid increase of social wealth and the fundamental improvement of people's lives. So the advantages of scientific and technological development are obvious.

On the Advantages and Disadvantages of Science and Technology (3)

Modern science and technology are changing the face of the world at an unprecedented speed and affecting people's lives. Food, clothing, housing and transportation are the most basic pursuits of human beings for thousands of years. With the development of modern science and technology, people's wishes are gradually realized, and people's lives are also beating the notes of science and technology.

Life expectancy has become "long"

1900, the average life expectancy in the world was only 45 years, but today this number is increasing to 66 years. The United Nations population agency has set the age limit for the elderly as "over 85 years old". The substantial extension of human life span benefited from the rapid development of medicine and the remarkable improvement of living standards in the 20th century.

Babies will be vaccinated with BCG soon after birth, and this vaccine has been tested in human body since 192 1, which eliminates the shadow of tuberculosis. Penicillin, hepatitis B vaccine, pacemakers, contraceptives, organ transplantation, artificial organs, microsurgery, ECG detection, ultrasonic diagnosis, magnetic resonance imaging and tomography (CT), which seem to be very common today, are all great achievements in medicine in the 20th century. The genetically modified cattle and sheep tested by China scientists in Shanghai have made mankind see the dawn of "animal pharmaceutical factory". The advent of test-tube babies and cloned sheep has made the fire of human life burn more and more brightly.

After the complete sequence of human genome is obtained, the decoding of human genetic code will enter a new stage of information extraction. Major disease genes will be discovered, and some life-threatening diseases will hopefully be cured.

The world is getting smaller.

2 1 century, information technology will develop from microelectronics to high integration, low power consumption and low cost, computers will develop in the direction of ultra-high speed, miniaturization, parallel processing and intelligence, and communication technology will develop in the direction of optical fiber, digitalization, integration and networking. The development of information technology will fundamentally change the basic way for human beings to engage in business activities, communication, entertainment, study and even work.

With the development of science and technology, human beings have broken through the limitations of time and space, and the earth has become a village for human beings. From highway to railway, from water transport to air transport, the progress of transportation has completely changed people's travel mode. 1903, the Wright brothers made their first flight with a plane made of wood, wires and cloth. Although the flight time is only 12 second, it is an epoch-making event. Today, the ever-changing aircraft manufacturing technology has enabled people to fly to any corner of the earth within 24 hours.

In the past hundred years, with the development of radio and network technology, information has been inserted into the wings of the speed of light. From telephone to telegraph, from radio to television, from mobile communication to fax machine, just like the "clairvoyance" and "clairvoyance" in ancient legends of China, it makes the communication between human beings more convenient. When you sit in front of your computer at home and click the mouse, your friends who are far away will receive your e-card in an instant. In Shangluo Mountain, Shaanxi Province, where Li Zicheng used to station troops to raise horses, farmers now do business all over the world through the Internet.

When human beings break through the space limitation, they also begin to break through the time limitation. With the invention of tape recorders, video cameras, video recorders, CD players and digital audio-visual equipment, we can leave our voices and smiles to future generations, and we can also hear and see the elegance of our ancestors.

Labor has become "light"

Science and technology have liberated all mankind, and the rapid development of science and technology has liberated more and more people from heavy manual labor.

The electronic computer is one of the greatest inventions of the 20th century. From the calculation of human brain to the calculation of computer, mankind has created the miracle that "human brain creates computer, and computer promotes human brain". In the 10 years after the first computer was put into operation, its calculation amount is estimated to exceed the sum of all the calculations in the history of human brain. Now, the problem of computer Chinese character input has been fundamentally solved, and countless people in China can roam freely on computers and the Internet with Chinese characters.

The great contribution of science and technology to social and economic development has increasingly proved that science and technology are the primary productive forces. It is estimated that the contribution rate of knowledge centered on science and technology to economic growth was 5% ~ 20% at the beginning of the 20th century, but at present this proportion has risen to about 80% in some developed countries.
