The theory on thing's limits. Part 1: The norm of identifying truth

Abstract

Things refer to the objects and phenomena in reality. Limits refer to the truths and the
processes of approaching them. Then there is the principle of inertia, which is characterized by
continuity, and a necessary condition for reasoning in reality. Therefore, thing, limit and inertia are
the three elements that constitute "The theory on thing's limits". Truth must have absoluteness and
immutability, does not exist in reality, and belongs to the category of metaphysics. The characteristic
of the truths is that they cannot be proved by empirical methods, and can only be gradually
approached by repeated practices. Based on this, this article has established the norm for identifying
truth. It not only has achieved the unity of opposites of all knowledge, but can also according to have
the characteristic of continuity on the change of objective things make bidirectional reasoning under
the premise of mutual restrictions. From the quantitative change in the real space has gone deep into
the qualitative change of ideal realm, it extends the philosophy of materialism to the category of
metaphysics. As a result, the true nature of metaphysics has been restored. That is to say, it has
neither divorced from practices, nor just observed objective things with a one-sided, isolated and
static way of thought. The theory is applicable to all academic categories, and it is to provide an
effective method for testing authoritative theories, clarifying chaos, and deriving new knowledge.
Finally, according to the theory and norm therein, combining with the objective status quo, this
article has briefly analyzed three examples and pointed out the crux of Einstein's special relativity.
