哲学从总体上教导人们善于认识和处理自己同外部世界的关系。在人与外部世界的关系上，不同的哲学派别有着各自不同的观点。由于旧唯物主义和唯心主义不了解实践，所以他们在人与外部世界的关系上各执一端，割裂了人与外部世界的统一关系。马克思主义哲学正确地解决了人与外部世界的关系，在哲学领域内实现了革命，其关键在于科学实践观的创立。 Philosophy as a whole teaches people to be good at understanding and dealing with their relationship with the outside world. In the relationship between man and the outside world, different philosophical schools have their own different views. Because old materialism and idealism did not understand practice, they both held their own position in the relations between man and the outside world and cut off the unification of man and the outside world. Marxist philosophy has correctly solved the relationship between man and the outside world and has revolutionized the field of philosophy. The key lies in the establishment of the concept of scientific practice.
