Step 1: Understanding the Concept:
The question refers to Auguste Comte's "Hierarchy of Sciences," which arranges scientific disciplines based on increasing complexity and decreasing generality. The science that "comes first" is the most basic and general one upon which all others are built.
Step 2: Detailed Explanation:
Comte's hierarchy of the six fundamental sciences is as follows:
1. Mathematics (The most general and basic)
2. Astronomy
3. Physics
4. Chemistry
5. Biology
6. Sociology (The most complex and specific)
Each science in the list depends on the principles of the ones that come before it. Therefore, Mathematics is the foundational science that comes first in his hierarchy.
Step 3: Final Answer:
Mathematics comes first in Auguste Comte's hierarchical principle of sciences.
