What's the difference between objective existence and actual existence?

The objective reality is the actual existence. In different fields, the proposition of "objective existence" has different provisions. In the different scope of ontology and epistemology, the meaning and content of "objective existence" are very different. Therefore, only by dialectically understanding the proposition of "objective existence" can we truly and scientifically grasp all its meanings and reasonably explain and explain various related issues. (1) In the field of ontology, according to Marxist philosophy, "objective existence" refers to objective things that exist independently of human consciousness. Marxist philosophy summarizes "objective existence" within the scope of ontology with material category. Lenin pointed out: "Matter is a philosophical category that marks the objective reality and is perceived by people through feeling. It exists independently of our feelings and is copied, photographed and reflected by our feelings. " (Selected Works of Lenin, Volume 2, page 128) The opposite category of consciousness is the reflection of objective existence by the human brain. Marx pointed out: "Conceptual things are nothing more than material things transplanted into people's minds and transformed in people's minds." (Selected Works of Marx and Engels, Volume 2, page 2 17) It can be seen that in the field of ontology, what exists objectively can only be material phenomena. The viewpoints of "nature is objective", "social existence and development are objective" and "the world around people is objective" in the textbook of "Ideology and Politics" in senior two use the proposition of "objective existence" in the ontological sense. As a reflection of objective existence, the phenomenon of subjective consciousness is not "objective existence" itself, whether it is the consciousness of the whole human being or the thoughts and concepts of a single person. The relationship between consciousness and matter, thinking and existence is the basic problem of philosophy. Different answers to the first aspect of the basic question of philosophy are the only criterion to distinguish materialism from idealism. Materialism holds that the origin of the world is matter, matter is primary, consciousness is the reflection of the human brain on matter, matter is secondary, and matter determines consciousness. In other words, only matter exists objectively and is the origin of the world. If consciousness is regarded as "objective existence", it will deviate from the fundamental viewpoint of materialism and lead to idealism. Zhu, an ancient thinker in China, believed that "reason lies in advance". Before the formation of the universe, there was an absolute and independent "reason", which evolved into various things and phenomena. Hegel, a German philosopher, believes that the essence of the world is "absolute spirit" and that nature and human society are the products and manifestations of the self-development of "absolute spirit" to a certain stage. Idealism reverses the relationship between matter and consciousness, which is fundamentally wrong in theory and extremely harmful in practice. In practical work, the relationship between matter and consciousness is objective and subjective. In order to effectively transform the objective world in practice and make practice successful, we must deal with the relationship between subjective and objective, persist in proceeding from reality, make the subjective conform to the objective and the thought conform to the reality. The so-called reality is an objective fact. We should decide our principles, policies, plans, working methods and other subjective things according to objective facts. On the contrary, if we don't try to be consistent between subjectivity and objectivity in our work, but start from subjectivity and cut objectivity with subjectivity, it will inevitably violate the objective law and lead to the failure of practice. Obviously, in the field of ontology, on the question of what is the origin of the world, there is a clear boundary between objective material phenomena and subjective consciousness phenomena, which cannot be confused. In this range, of course, other people's ideas are not objective, but a reflection of objective existence and subjective. (2) In the field of epistemology, "objective existence" not only refers to the material world as a whole, but also has special provisions. Dialectical materialism epistemology first thinks that knowledge is the reflection of the objective material world. This is the general principle of materialist reflection theory and answers the basic line and starting point of materialist epistemology. At the same time, dialectical materialism epistemology especially emphasizes the decisive role of practice in cognition, and lays knowledge on the basis of practice. This is the fundamental difference between dialectical materialism epistemology and old materialism epistemology.
