As Einstein said, the end of physics is philosophy, and the end of philosophy is philosophy. Science is a discipline that studies positivism, and science must be completed in the form of theory. As the highest level of theory, philosophy is naturally the end of science. Theology differs from science. Theology has no material basis. The essence of theology is man's irrational belief. Because of its non-positivism, theology lacks science. But in terms of emotional will and belief, theology shows eternal concern for people's hearts. Philosophy is between science and theology. Science provides people with material foundation, theology provides people with eternal spiritual care, and philosophy balances the relationship between science and theology. Whether philosophers, scientists or ordinary people, the end of life is death. As an eternal description of the illusory world, theology is naturally the best destination for people. Theology gives nothing. People go to theology because they have an eternal sustenance when they want to die. So theology is a system of faith, not superstition. It is very important to understand this.
