Philosophy and concrete science interact. The prosperity and stereotype of a certain science has an impact on philosophy, and its achievements, methods or public opinion images penetrate into philosophy, guiding the thinking mode and goals of philosophy. But this is not always without problems. This paper discusses mathematics, a discipline that runs through the history of philosophy and has a far-reaching influence on philosophy. To be exact, it discusses the prosperity and dissolution of mathematics' exemplary role in philosophy, which is often based on the question of truth.

Generally speaking, mathematics has always been regarded as the embodiment of thoroughness, reliability and effectiveness. This makes mathematics occupy a special position in human learning. The self-evident concept, abstract reasoning and definite conclusion of mathematics have won the most lasting admiration of philosophy. If philosophical truth is to stand, it must reach the level of mathematical truth. This kind of consciousness almost dominates the mainstream form of western philosophy.

Of course, when philosophy imitates mathematics, it is not necessary to completely quantify the content, because the subject matter of philosophy obviously cannot be handled so mechanically. What philosophy should get from mathematics is the establishment of self-evident initial concepts and convincing logical methods.

An ideal scheme is: grand and complex philosophical themes, together with unconvincing logic, constitute a judgment system. For it, all asserted truths are true, and all possible truths are also included.
