The concept of information

Hartley came to the very beginning of the concept of information, the field of communication.

Shannon believes that information is the key to the elimination of uncertainty.

Brillouin thinks that information is negative entropy. (entropy is a symbol of disorder), negative entropy is the elimination of uncertainty.

Ontology level: Information is the way things exist or the state of movement.

"Things" refers to human society, thinking activities and all possible objects in nature.

"Means of existence" refers to the internal structure and external relations of things.

"Movement" refers to all changes in meaning, including mechanical, in-house, chemical, biological, thinking and social activities.

"Movement state" refers to the characteristics, situation and law of the change of things in time and space.

The level of epistemology: information is the way or the state of being in which the subject perceives or expresses things.

At the level of epistemology, there is no information without subject, and the existence of information is not premised on the existence of the subject at the level of subjectivity.

The concept of information at the level of epistemology has richer connotation than subject theory, because the subject has the ability of perception, comprehension and purpose.
