Truth:
? Truth is usually defined as being consistent with facts or reality. However, no definition of truth is generally accepted by scholars. Many different definitions of truth have been widely discussed. Many topics related to the definition of truth are also unable to acquire knowledge.
Truth is an unavoidable concept for philosophers when facing the meaning and problems of life. Many philosophers claim to represent the truth, but they may have nothing in common or even be tit for tat. In daily life, many people also claim that their opinions are truth. Seeking truth may be one of human nature, but consciously distinguishing between true and false begins with parmenides's distinction between "the way of truth" and "the way of opinion": "Truth is regarded as eternal", which is also the most popular description of truth. Aristotle thought about truth for the first time, and almost all modern theories of truth can be traced back to him. Metaphysics recorded his famous saying: "what is not said is what is not said, which is false;" Indeed, what is said is not said.
Truth semantics theory
The semantic theory of truth holds that for a given language, any acceptable definition of truth should follow all examples of the following patterns:
Logician and philosopher Taskey developed the theory of formal language. Here, he constrains this theory in the following way: a language cannot contain truth predicates on itself, in other words, the expression of "truth" can only be applied to statements in other languages. The latter language he talked about is called object language (then, object language may contain truth predicates applied to statements in other languages). The reason for this restriction is that languages that contain truth predicates will contain paradoxes. Therefore, Taskey believes that semantic theory cannot be applied to any natural language, such as English, because they contain truth predicates themselves. Davidson regards this theory as the basis of his truth conditional semantics, and connects it with thorough explanation in the form of integration.
Some things naturally become truth through the experience of predecessors, and those truths can really help us a lot and help us solve many problems. So the reason why truth can form truth is also very reasonable.
