Which Dewey Decimal classification is associated with Philosophy?

The correct classification for Philosophy in the Dewey Decimal system is found within the 100's category. This classification encompasses various subjects that deal with fundamental questions regarding existence, knowledge, values, reason, and language. Subcategories include specific branches of philosophy such as metaphysics, ethics, and logic, which are all integral to understanding philosophical discourse.

The choice of the 100's category is significant because it distinguishes philosophical works from other fields of knowledge, placing them among the foundational disciplines that explore human thought and inquiry. Philosophy often overlaps with subjects in other classifications, such as religion or social sciences, but its core tenets and exploration of abstract concepts are firmly rooted in this numerical range.

In contrast, the other classifications mentioned correspond to different domains: 000's covers general knowledge and computer science, 200's pertains to religion, and 500's focuses on natural sciences and mathematics. Thus, recognizing that philosophical studies fall within the 100's aligns with the overarching structure of the Dewey Decimal Classification, which organizes knowledge in a systematic way.
