Many philosophical questions have not yet found an accurate answer, but we cannot say that philosophical questions are questions that can never be answered. There are many questions that have no answers, such as ancient mysteries, theological issues, UFO issues, and many other mysterious phenomena, but these are not philosophical issues. On the contrary, philosophical issues can have answers. For example, the standard of truth, with the development of philosophy of science and technology, has gradually formed a lot of consensus.

There will be mistakes in theories, people will be led astray, and even disasters, but we cannot completely abandon theories and we cannot give up the efforts to improve theory. The unity of believe and doubt, and the unity of pragmatism and ideal is a scientific attitude toward theory.

When we encounter pains and difficulties in life, we need help from science, but scientists have found that they must resort to philosophy. Otherwise, scientific theories cannot be justified. The important conclusion in science is called the theorem, but how do you prove various conclusions and theorems? Many of the theorems seem to be clearly correct, but they are later overturned. For example, how many parallel lines can be made through a point outside a straight line. There is only one in Euclidean geometry, and there are countless lines in non-Euclidean geometry. Originally, everyone thought that the material is immortal, and later found that positive and negative particles can disappear together; we used to believe that particles are real, and later Quantum mechanics says that the appearance of particles is a probability. Then will all theories be overturned in the future? Are there any unchanging truths? In the end, what is truth and how to prove the truth? Scientists must ask philosophers for advice about these questions.

What kind of theory can provide people with faith? All philosophical theories and religious theories can provide people with beliefs, but if a theory is not thorough, it cannot be justified by itself,
