Theory of Science by A. Comte

Comte believed that all sciences consist of both theoretical and applied knowledge. Theoretical knowledge is divided into general fields (e.g., physics, biology) and detailed fields (e.g., botany, zoology, mineralogy). Hierarchy of Sciences: Comte proposed a hierarchy of main scientific fields based on complexity and theoretical tools: Mathematics: The most general science. Astronomy, Physics, Chemistry, Biology: Ordered by decreasing complexity. Sociology: The most complex science, dealing with human societies. Each science builds upon the previous ones. Interconnectedness: To study chemistry methodically, one must understand physics, as chemical phenomena are more intricate than physical phenomena. Sciences classified earlier are foundational and more advanced than those presented later.
