Are all theories or truths that have not been verified by themselves false?

Too absolute. If it's a discriminatory question, it's definitely wrong.

Philosophically speaking, truth requires practice, but practice is conditioned by conditions, and the correctness of practice is related to people's subjective cognitive ability. To use a simple analogy, many truth theories cannot be practiced by a person, but after being practiced by others, you have used them through understanding, and you must not say that you are wrong because you have not practiced them yourself. Timeliness is your own practice, but due to your own limited understanding, even wrong, affected by the degree of development of science and technology at that time, or special conditions, the truth can be said to be relative, and cannot be absolute.

So truth and theory are developing.

It can only be that it is not accurate to you, how can it be said that it is wrong. In fact, it is you who will do wrong in this way, not the error of the truth, it is natural and cannot be left to you.

Summary. Because what has been proven by practice is an adjective.

Why can't a theory that has been proven scientific in practice be the criterion for testing the truth of understanding?

Because what has been proven by practice is an adjective.

You see clearly. The real subject is the theory.

That is, consciousness.

And practice is the only criterion for testing truth.

It's been tested in practice.

Rationale can not be a test of the other.

What about the criteria for knowing truth?

To put it bluntly, truth is consciousness after subjective judgment.

Practice is what he is an objective substance. You just need to remember clearly that practice is the only criterion for testing the truth, and it is the only one, and it is not a good way to see the collapse of sentences when doing questions.

There is no absolute truth, its object is constantly changing over time, and truth is conditionally concrete

"Practice is the only criterion for testing truth? "Clarification.

Truth is the value of the end, and practices are procedures – these procedures, when carried out, are constantly modified by artificiality, so reality cannot be called truth! This is the phenomenon that needs to be discerned in opinions. Because it is only a modification factor in the process, and can only represent a theory or logical inference, it is an act of advertising or invitation to make an offer, and it is not necessarily a ...... that is promised and implementedTherefore, an opinion that is not supported by the end of things or things can never be called truth!!

This is also the strongest factual phenomenon that has been praised as "practice is the only criterion for testing truth" in reality, but cannot be verified, and we cultural people need to distinguish it.

In line with the topic, so far, human understanding of the moon is still intuitive, vivid, and shallow, because from the perspective of the subject of cognition, people's understanding of objective things is limited by the specific level of practice; From the point of view of the object of cognition, there is a process of exposing and revealing the essence of complex things.

It is wrong to say that the process of human cognition is a wave-like forward or spiraling process, not a circular movement;

The whole process of people's search for truth is not always accompanied by mistakes.

Therefore, a is selected for this question

The reason why practice can be used as the test criterion of truth is determined by the nature of truth and the characteristics of practice.

First of all, from the point of view of the nature of truth, truth is the correct reflection of objective things and the laws of their development, and his nature lies in the correspondence between subjectivity and objectivity. Therefore, as the criterion for testing truth, we cannot look for it in the subjective realm, nor can we look for it in the realm of theory, and ideology and theory itself cannot become the criterion for testing whether or not we conform to objective reality.

Secondly, from the perspective of the characteristics of practice, practice is an objective material activity for people to transform the world, and it has the characteristics of direct reality. Practice has the property of linking ideas with objective reality. Therefore, it is practice, and only practice, that can accomplish the task of testing the truth.

(1) Truth is a philosophical category that marks the conformity of subjectivity and objectivity, and is the correct reflection of objective things and their laws. The most basic attribute of truth is objectivity. (2) Due to people's different positions, viewpoints and methods, each person's knowledge composition, cognitive ability and level of understanding are different, and they will have different understandings of the same definite object, but there can only be one correct understanding, that is, there can only be one truth.

Therefore, there is only one truth that is true for the same objective thing. (3) Any truth is the concrete historical unity of subjectivity and objectivity, theory and practice, and truth must be constantly enriched, developed, and perfected along with the changes in historical conditions. Otherwise, truth will be transformed into falsehood.

Therefore, it is a mistake to think that truth is immutable.

Can objective things tell what is right or wrong? Objective things are objective. It doesn't matter if it's right or wrong.

The only criterion for testing the correctness of understanding. It is only in practice that subjective perception and practical results can be compared. If the result of practice meets the requirements of the original understanding, the understanding is correct.

Otherwise, it is wrong.

Fallacies, that is, erroneous understandings, arise because the subjective does not form a true reflection of objective things on the basis of practice. Failure to insist on proceeding from reality in everything and seeking truth from facts.

The absoluteness of truth mainly indicates that things can be and can be finally known, including the objectivity of arrangement, the knowability of the world, and the development of truth. The absoluteness of truth refers to the fact that a certain stage of knowledge is limited, and is a link in the eternal development of truth. Contains the breadth, depth, and process of understanding.

1. Mutual transformation and mutual penetration, there is absolute in the relative, and the absolute is in the relative. 2 Dialectical transformation, any truth develops from relative to absolute eternity.
