Why is it philosophical to say that science is philosophical?

From the content, it can be seen that Rigaku belongs to the school of philosophy.

In a nutshell, the main issues discussed in science are: Ontology.

The problem is the original problem of the world. On this issue, the theorists, although different, all denied the existence of a personal God and the other world. Jang Zai.

He put forward the philosophy of qi ontology, believing that the qi of the void is the origin of all things. Ercheng established the ontological philosophy of "heaven is reason", believing that conceptual reason is the origin of the world. Zhu Xi.

He put forward the doctrine that reason is the "foundation" and qi is the "tool". The problem of the theory of the mind, that is, the relationship between human nature and the heart, sex, and emotion. Zhang Zai put forward the theory of the nature of heaven and earth, the nature of temperament and the temperament of the heart, and believed that the nature of heaven and earth is the first in the air of the void. Cheng Hao.

He put forward the proposition that the heart is heaven and that sex has no inside and outside, and unified the heart, sex, and heaven. Cheng Yi.

then put forward the proposition that sex is reason, and say that sex is a metaphysical reason. Zhu Xi believes that the essence of the mind is sexuality, which is in the process of being undeveloped; The function of the heart is affection, which is the sum of what has been made; Sex and affection are the relationship between the body and the body, and the heart is the "master". Epistemological problems, i.e., epistemic problems and epistemic methods.

Zhang Zai first proposed two kinds of knowledge, "knowledge of seeing and hearing" and "knowledge of virtue", and advocated the study of exhaustive reason, which became a common discussion issue among physicists. Ercheng put forward the epistemic theory of "learning from things"; Zhu Xi proposed a systematic approach of "that is, the principle of material exhaustion"; Lu Jiuyuan emphasized "reflection"; Wang Shouren.

He put forward the theory of "to conscience", and believed that the knowledge of things is to the conscience of my heart to things and things, so as to complete the line of understanding from the inside out.

It has a philosophical character: it belongs to a systematic and theorized worldview. The main task is to understand the world and transform the world, and to understand the world is to understand the world and to have its understanding of the origin of the world, and to transform the world refers to its practices in governing the country and controlling people's thoughts, and so on.

It's like philosophy in itself.

How to define science, a collective term for mathematics and natural sciences.

In terms of scientific research, natural science, social science, and thinking science are the three major categories.

Philosophy, on the other hand, is neither a natural science, nor a social science, nor a science of thinking, but a separate category.

But there is also a general view that puts philosophy and the social sciences together.

Philosophy belongs to the social sciences and is partial to the liberal arts.

It's the liberal arts, and the fourth book on the politics of the liberal arts is to study philosophy.
