In historical order: theology, philosophy, mathematics, science. Humans need mathematics to understand physics in this way, rather than the source of physics is mathematics; The sources of physics are "existence" and "the existence of objects", so science and mathematics are viewed in parallel, and their sources are philosophy; Theology is a necessary process for human beings, but the destination of philosophy is agnosticism, not theology; Philosophy and theology have the same nature, that is, the response to the "ultimate cause". Although the theological answer is very emotional, philosophy seems to use reason to push to the answer that cannot be found, and the essential starting direction is still the same; Therefore, science and mathematics are parallel, and philosophy and theology are parallel. So the order of history is theology, philosophy, mathematics and science.
