Therefore, the condition of judgment is to have two concepts, one is called subject, and the other is called predicate or predicate. The subject-predicate relationship can be divided into two kinds of judgments: analytical judgment and comprehensive judgment.

Analysis and judgment: the meaning of the predicate is contained in the subject, that is to say, the predicate is capable.

Obtained from the analysis of the theme. All of them are direct analysis and do not need empirical verification.

For example, people are rational animals and objects are plastic.

Comprehensive judgment: the meaning of the predicate is not included in the subject, that is to say, the predicate is

Not by analyzing the theme.

For example, the A people are short and Zhang San is a good person. Kant also believes that knowledge is not composed of a single concept, but must be expressed by judgments containing subject and predicate, so judgments must be included in some rules to distinguish them. Judgment must be made through practice, not only by abstraction or imagination. And in the process of our understanding, is judgment innate? In order to solve this kind of problem, he combined "congenital and acquired" and "analysis and comprehensive judgment" to discuss and find out the answer. Therefore, it is considered that the following situations may occur:

Natural analysis and judgment

(All analytical judgments do not need to be verified, so they are congenital analytical judgments. )

Analysis and judgment

Acquired analysis and judgment

(It is already an empirical fact, so there will be no empirical judgment, so it does not exist. )

Transcendental synthesis

(Not from experience, absolutely universal)

synthetic judgment

Acquired comprehensive judgment

(it is derived from experience, so it is more common and exceptions can be found. ) From the above, it can be seen that there is no "acquired analytical judgment" in the judgment of knowledge, and "analytical judgment" can be directly derived from analysis without empirical verification. In other words, all analytical judgments are innate. So the only way to analyze and judge is "innate analysis and judgment". As for the "acquired comprehensive judgment" in the "comprehensive judgment", it is actually experience, so the conclusion it draws will have a relative meaning. Therefore, Kant believes that transcendental judgment is mainly "innate comprehensive judgment", and its existence is possible. He thinks there are three kinds of judgment is consistent:

(1) Mathematical judgment: For example, "The straight line between two points is the shortest distance"

Reason: (1) synthesis: predicate: "the shortest distance" cannot be obtained from the analysis of the subject: "straight line".

(b) Innate: It doesn't come from experience (maybe you can get it from experience), so it is universal.

(2) Physical judgment (natural science judgment) such as: "In all changes of matter, its quantity remains unchanged."

Reason: (as described in (1))

(3) Metaphysical judgment: For example, "The world has its first principles."

Reason: (as described in (1))

Finally, through the above discussion of "transcendental method" of transcendental judgment, Kant turned the traditional research direction of epistemology system to the cognitive structure of subject. Kant believes that human cognitive ability has three parts: sensibility, understanding and rationality. Using the above transcendental methods, the contents of transcendental sensibility theory (about sensibility), transcendental analysis theory (about understanding) and transcendental dialectics theory (about reason) were developed respectively, and the epistemological system of transcendental criticism in his Critique of Pure Reason was constructed.
