The subject refers to the person engaged in practical activities,
Object refers to the sum of the active objects of the subject,
Intermediary refers to various forms of tools, means or methods to contact subject and object.
For example, if you write a paper with a computer, you are the subject, the paper is the object, and the computer is the intermediary.
The concepts of subjectivity and objectivity emphasize a way of thinking and what angle and attitude to take to study or think about problems. Philosophically, it mainly appears in two places, and others are extensions of these two concepts.
1, when learning idealism, idealism is divided into subjective and objective, and idealism is divided into subjective idealism and objective idealism.
2. When studying the world, we divide the so-called world into subjective world and objective world.
Simply put, subjectivity is human consciousness, and objectivity is everything except human consciousness, including people's creative trance.
