The truth can be defined as obeying reality or reality, and in order to make something "reality" it must be open, eternal and independent. If "truth" does not meet these guidelines, it is not "real". Clearly, everything that violates the "truth" boundary is definitely wrong. Truth and error seem to be not a simple black and white situation in many cases, sometimes there may be no reason to decide what is true and what is false. All truth is a matter of opinion. Truth is related to culture, history, language and society. All the truth we know is a subjective truth (ie the truth that depends on the soul).
For example, in physics, Newton's law of gravity can be determined to be nearly 100%, but it can not be said that this is absolutely correct. For example, if you put a pencil it will fall, but what happens will be what happens when released. So we can not really say this law. In order to make this law 100% sure, we need to know that it is impossible in the future. It can not be said that this is fake, but completely incorrect things will not automatically become wrong.
I would like to explain this claim using another example in another knowledge field, art. Taking an illustration of Mona Lisa as an example, some people think that they are actually watching the audience, others think that they are not watching, others think that they are crying in the picture, and smiling Some people imagine. Therefore, all of these audiences are right, as Mona Lisa is not smiling, or Mona Lisa can not blame someone to say that they are crying, or doing nothing. This is actually dependent on the viewer's perception, emotion, and reasoning ability. If a happy audience may find her smile, a bad mood may find that she is crying. Therefore, it depends on the psychology of the person looking at the picture at that time. In this case, inference is mainly emotion
Objectively speaking, there may be universal truths, perhaps subjectively, everyone has their own truth. Personal truth is neither right nor wrong for outsiders. To others, "No, believe this" is very arrogant and impolite. Open discussion is one thing, argument in the narrow sense is another matter
I would like to say that the truth exists outside of us and can be seen by anyone. Unfortunately, the real conclusion against the truth is more complicated, as humans can be stubborn. There are two kinds of truth in society: subjective truth and objective truth. The subjective truth is given to us through our personal experience related to the people around us: in short, this is the truth we proposed. Objective facts are discovered through searching. This is essential to our experience until sufficient evidence is gathered. Subjective truth is not always opposite objective truth, but it is not from other people, it depends on the emphasis of the theme for their view of the world.
In Kierkegaard, objective truth is characterized by extrinsicity and subjective truth is characterized by intrinsicity. Objective thinkers do not find eternal happiness in subjective truth, but they are not interested in subjective truth. Objective thinkers are interested in the definition of existence, but subjective thinkers are interested in the definition of existence. Consideration about the nature of existence may be objective or subjective. The truth can be reflected objectively or subjectively. Kierkegaard believes that an objective thinker discovers the truth by approximation and a subjective thinker uses it to discover the truth. Objective thinkers need to quantify certainty or probability, subjective thinkers finally have to accept uncertainty. According to Kierkegaard, it can not be achieved by estimating trust, or by trying to quantify the review more certainly.
