Renaissance is an ideological and cultural movement, which brought about scientific and artistic revolution and opened the curtain of modern European history. The Renaissance movement is an ideological emancipation movement that greatly promoted the progress of human society and a bourgeois movement against feudalism and theological world outlook. It has promoted the development of modern scientific undertakings such as culture, art and navigation, promoted the development of capitalism, impacted theology, emancipated the mind, and promoted the development of social productive forces and the improvement of production technology. Renaissance had a certain influence on the progress of human society, literature and art. Key words: Renaissance humanism, primitive capital accumulation and ideological emancipation. Engels once spoke highly of the Renaissance. He said: "This is the greatest and most progressive change that mankind has never experienced. It is an era when giants are needed and produced-giants in thinking ability, enthusiasm and personality, versatility and erudition." Renaissance is an era when giants were born, and many scientific and artistic giants appeared. In science, there are Copernicus, Bruno and Galileo. They put forward different views from traditional ideas and opened up a new era of science. In literature, there are "three outstanding writers": Dante, Petrarch and Boccaccio, who pursue knowledge and criticize old religious ideas. There are three outstanding artists in the art world: Leonardo da Vinci, Michelangelo and Raphael. The humanistic spirit of Renaissance is the expression of social progress, which promoted the transition of human society from feudal society to capitalist society. It liberated the human mind, broke Europe's understanding of the world, society and people for centuries, broke through the inherent religious concept, promoted the religious reform and liberated people's minds. Renaissance revealed man and his greatness, affirmed his value and creativity, and put forward that man should be liberated and his personality should be free. Paying attention to people's value requires giving full play to people's intelligence and creative potential, opposing a passive attitude towards life, and advocating the spirit of being proactive and adventurous. Attaching importance to the worldly life and despising the illusory myth about the afterlife or heaven has uncovered the cloak of religion, made people look at the world more rationally and dialectically, and highlighted the people-oriented thought. Renaissance is the ideological weapon of bourgeois anti-feudal and anti-theological world outlook; It opened the way for the later Enlightenment. The Renaissance broke the situation that religious mysticism dominated the whole country, powerfully promoted and influenced the religious reform movement, and provided important help to it. It broke the unified situation of scholasticism, cleared the way for future ideological progress, made various secular philosophies rise, denied feudal privileges and divine right, broke superstition, liberated thoughts, and restored the value of rationality, dignity and thinking. Renaissance, as an ideological emancipation movement to promote the emerging bourgeois culture, laid a solid foundation for the budding development of early capitalism in the process of communication, and also accumulated original wealth for the early bourgeoisie. The Renaissance promoted the development of the maritime industry, thus laying the foundation for opening up new navigation channels and plundering the original capital by sailing around the world. There has been a revolutionary leap in navigation technology, and explorers from Portugal, Spain and Italy have started a series of long-distance navigation activities. The geographical discoveries of Columbus and Magellan provide strong evidence for the theory of the earth circle. Based on the original capital, it further promoted the rise of Portugal, Spain, the Netherlands and other big countries. The Renaissance opened up another road to the East for Europeans-the ocean, which made the wealth of the East, especially silk, spices and cotton, flow into the European market in large quantities, greatly improved the living standards of Europeans, swept away the haze of medieval Europe, and expanded the scope of economic trade and economic growth in Europe. Renaissance had a wide and profound influence on natural science, philosophy, education and even lifestyle at that time, and promoted the development of human society at that time to a certain extent. The in-depth development of the Renaissance has revolutionized people's understanding of various phenomena in nature, which also provided conditions for the vigorous rise of modern natural science. During this period, there have been many great leap forward developments in geography, architecture, physiology, medicine, mathematics and astronomy, such as the development of algebra, Galileo's three laws and Heliocentrism's proposal. This rational thinking strengthened by the scientific and technological revolution has also built a bridge for the transition of human thought from humanism to rationalism. 15 and 16 centuries can be marked by renaissance humanism, 17 century by scientific revolution and 18 century by enlightenment rationalism. This order is not an accidental arrangement, but an inevitable process of historical development: the Renaissance movement turned its attention from God to man, and it was full of passion and rational germination when it held high the banner of humanism centered on people; Scientific research and technological activities have made the germination of rationality have a soil for further development, and scientific and technological achievements have more reflected the light of rationality and verified the correctness of rationality; Without the rational foundation laid by the scientific revolution in17th century, there would be no surge of rationalism in18th century. Enlightenment scholars took the banner of rationality from science, unified rational thought and popularized it to the public. The most direct role of scientific and technological revolution is undoubtedly reflected in the changes in social economy, social life and social relations. In promoting economic development, science and technology have been transformed into productive forces, and they have begun to play the role of primary productive forces, which has doubled, tenfold or even hundredfold the efficiency of labor production and brought enormous economic benefits to society, thus building an increasingly strong material foundation for social progress and development and laying a solid material foundation for the first and second industrial revolutions. In social life, science and technology unveiled the mystery of nature, and guided human beings to explore and conquer the natural world boldly, instead of being keen on the struggle between people, thus simplifying the relationship between people. Science and technology have brought advanced transportation and communication tools, which have brought people in different parts of the world closer together, expanded the scope of people's activities, and thus made social life more colorful. As for social relations, on the one hand, science and technology during the Renaissance were promoted by many factors of social relations. After the century, the feudal relationship of 15 was loosened, the closed and rigid social structure was changed, and the rulers' policies were more flexible. Therefore, people's geographical mobility and occupational mobility are becoming more and more frequent, and more and more laborers are engaged in scientific undertakings and technical activities. On the other hand, the scientific and technological revolution has gradually formed new social relations. People engaged in scientific and technological work also face livelihood, tools, instruments, social and economic problems every day; Their inventions are not isolated, and they must rely on the cooperation and attitude of other scientific and technological personnel and other members of society. This interdependent social relationship is an important symbol of modern society. Science and technology itself has a close and strict division of labor, and all links must have a high degree of cooperation, so there is a dependence on the working relationship. Division of labor and cooperation is one of the main ways of modern society. Therefore, people obtained the cultivation of science and technology, which strongly promoted the development of human society at that time. During the Renaissance, a large number of exquisite works of art and literary masterpieces were created, such as The Divine Comedy, decameron, Tangji River, German, The Last Supper and David. They embody humanism: they advocate individual liberation and oppose asceticism and religious views in the Middle Ages and the Middle Ages; Advocate scientific culture, oppose obscurantism, and get rid of the shackles of the church on people's thoughts; Affirm human rights, oppose theocracy, and abandon all authority and traditional dogma as the basis of theology and scholasticism; Supporting centralization and opposing feudal separatism are the main ideas of humanism. European art, especially painting, has basically completed the development of three lines: a trend born out of medieval art, focusing on lines and beautiful shapes; The second is to introduce a sense of sculpture into the painting, emphasizing the muddy feeling of the body; The third is to pursue atmosphere, that is, to create the illusion of the reproduced object by exerting the changes of light, shadow and color. Of course, these three trends will not go their own way. Sometimes they cross convergence and sometimes they diverge intermittently. Renaissance is the pioneer of the modern world. The modernity of the world is marked by two characteristics: one is the modernization of ideas, and the other is the development of science and technology. The achievements of Renaissance artists in perspective and human anatomy laid the foundation for the discovery of modern science. Similarly, their works have also made important contributions to the emergence of modern ideas. The core concepts of modernity are freedom, progress, individuality and creativity. The story of the Renaissance shows that these thoughts are endowed with vivid forms through art, even if they are not directly derived from art. Although the Renaissance movement has had a very significant impact on history, from a dialectical point of view, it overemphasized the value of people in society and attached too much importance to people's freedom of thought and personal freedom, which led to people's depravity and led to some people's life erosion and lack of faith to some extent. But at present, the influence of Renaissance on human society, humanities, art and science and technology is far greater than its negative influence, leaving great wealth to modern society.
