The cultivation of universities can make a person have a richer knowledge reserve and become a specialized person in a certain field; The significance of university education also lies in improving individual cognitive level and making them look at the world more rationally; In addition, the guiding education of universities has stimulated the potential of independent and dynamic development of college students; After studying and living in university, intellectuals can better understand and give back to society. According to different majors, universities have set up special training programs for college students. The training plan includes two parts: curriculum and practice. The curriculum includes basic courses, specialized courses and rich elective courses. The practice part is based on curriculum group and comprehensive graduation thesis design, which can increase students' mastery of knowledge and improve their innovative ability. After four to five years of systematic education and training, college graduates can master professional knowledge in a certain field, have excellent professional skills, and have professional ethics and spirit that match their work. Through college education and self-study, college students can not only increase their professional knowledge, but also improve their cognitive level of natural science, social phenomena and people themselves. Cognitive level directly affects a person's purpose, attitude and method of treating things. Kant believes that the scientific knowledge acquired by human beings through "intellectuality" is the understanding of "phenomenon world". And things in the "phenomenon world" are relative and conditional. It is the highest cognitive activity ability of human beings to further "synthesize" and "unify" all kinds of intellectual knowledge into unconditional and absolutely complete knowledge, which is called "rationality". Looking at the world rationally, when facing the same world, can make a person get more information, richer feelings and more truly feel the meaning of life.
