Whether thinking and existence are identical, that is, whether thinking can correctly reflect existence.

If you believe that thinking and existence are identical, that is, thinking can correctly reflect existence, it is knowability.

If you think that thinking and existence are not identical, that is, thinking cannot correctly reflect existence, you are agnostic. ?

The opposition between agnosticism and agnosticism: Agnosticism does not recognize the identity of thinking and existence, denies people’s ability to understand the world, and does not believe in science; agnosticism recognizes and insists on the identity of thinking and existence, and believes that the world It can be understood. People have the ability to understand the world and believe in science. Therefore, the identity of thinking and existence is to advocate the theory of knowability.

Extended information:

Thinking is the activity of the thinking subject processing information and consciousness. The thinking subject is a substance that can perform active operations on information (such as collecting, transmitting, storing, extracting, deleting, comparing, screening, judging, arranging, classifying, disguised, transformed, integrated, expressed, etc.). Thinking subjects include both animals (such as humans) formed by natural evolution, and there are also artificial intelligence products that are gradually developed and improved.

The objects of thinking activities are information and consciousness. Information is the phenomenon and appearance of things that can be recognized by the thinking subject. Consciousness is the product of thinking activities. Consciousness is stored, expressed and output in the form of information. The communication of consciousness The essence is information dissemination. Consciousness often becomes the basis for the thinking subject to carry out the next step of thinking.

The words thinking and consciousness here represent different things respectively, but people often regard them as the same concept. This situation can easily cause confusion in people's understanding, so attention needs to be paid to the distinction. The philosophical meaning of existence (reality). In the narrow sense, existence is a philosophical category synonymous with matter relative to thinking; in the broad sense, it is a category synonymous with existence relative to nothingness (seeing existence and non-existence). It is a category of all material phenomena and The sum total of mental phenomena.

In the history of philosophy, the category of existence has been widely used by philosophers of various schools, but has been given different meanings. Medieval Christian theology believed that God was the most real existence, and modern subjective idealist Berkeley believed that existence is to be perceived. The German objective idealist Hegel regarded existence as the simplest determination of the absolute concept.

Modern Western existentialists interpret existence as individual subjective existence. Dialectical materialism believes that although the existence of the world is the premise of the unity of the world, the unity of the world must be abandoned when explaining the unity of the world. This vague formulation of existence insists that the unity of the world lies in its materiality; the relationship between existence and thinking, matter and consciousness is a basic issue in philosophy.
