Classifying Fields Of Knowledge

This is a classification scheme for knowledge that I came up with. I’m explaining it here because I reference it a few times in my other webpages, mainly because the terminology is convenient to use. The idea is that fields of knowledge can be organized depending on whether the non-existence of the Universe, the Earth, humans, or oneself would cause the knowledge itself to become useless.

The idea behind this schema is that it’s a way to organize fields of knowledge with regards to what that knowledge is relevant to. My individual-centric knowledge wouldn’t be relevant to anything if I never existed, the human-centric sciences wouldn’t have any relevance if humans never existed (although many of them would still be relevant to hypothetical intelligent life on another planet), and Earth-centric knowledge would lose its relevance/usefulness if the Earth stopped existing. However, Universal Sciences remain relevant throughout the entire universe, regardless of whether humans or Earth exist or not at all. I make a lot of references to these terms when I write about my theory of epistemology (still in development).

In epistemology, I’ve formulated a similar structure for thinking about knowledge:

• Individual-centric Knowledge (knowledge that is only relevant to an individual, e.g. their personal identity, life history, ancestral lineage, their own experiences, etc),
• Human-centric Knowledge/Sciences (social skills, anthropology, economics, media arts, world history, linguistics, sexology, technology, epistemology, etc),
• Earth-centric Knowledge/Sciences (geology, biology, geography, knowledge of the observable universe and Earth’s solar system, etc), and
• Universal Sciences (Mathematics, Physics, Chemistry, Astronomy, Planetary Geology & Biology, Metaphysics)

To an extent, this reminds me of this modified xkcd comicstrip #0435 “Fields Arranged by Purity”:

Knowledge can be divided up in this way, although there are specialized fields within the more abstract ones. For example, geology is a specialization of physics, psychology is a specialization of biology. We can define types of order: metaphysical presuppositional, physical, biological, psychological, cultural, social. Each requires its own concepts and theories. Arguably, every field of knowledge requires its own concepts after a certain level of complexity is reached, and those may not be reducible to its parent field’s concepts, lest the field of knowledge be too overwhelming and incognizable. Then there is also personal knowledge, which for each of us is primary. Like your own life story, for example.

The more abstract fields have implications for the more specialized fields, but not vice versa. For example, biology has implications for psychology and sociology, but biology can’t be understood through psychology and sociology alone.

Higher Than Universal: Knowledge that would still be relevant in a hypothetically Different Universe.

• Philosophy
• Mathematics
• Computer Science

Universal Sciences: Sciences that have universal application and relevance to every location within the Universe.

• Philosophy
• Mathematics
• Physics
• Chemistry
• Astronomy
• Planetary Geology & Biology

Earth-Centric Sciences: Sciences that have relevance to us only because they are centered around the Earth.

• Knowledge Of The Observable Universe & Our Solar System
• Earth Sciences
• Geology
• Geography
• Biology

Human-Centric Sciences: Sciences that have relevance to us only because they are centered around humans, but could have some relevance to another intelligent alien civilization.

Individual-Centric Knowledge is defined as knowledge that only has relevance to a handful of individuals and no one else.

• Culture & Society & Language
• Familial Lineage
• Life History
• Interpersonal Connections
• Intrapersonal Knowledge
• Place Of Residence & Surroundings
• Property & Finances & Belongings
• Occupational Work & Skills
• Hobbies

• Chemistry - Periodic Table
• Astronomy - Hertzsprung-Russel Diagram
• Geography - World Map
• Geology - Rock Cycle Diagram / World Map of Tectonic Plates
• Statistics - Normal Curve Distribution
• Human Anatomy - Human Body Diagram
• Neurology - Human Brain Model
• Quantum Mechanics - Rutherford–Bohr Atomic Model
• Economics - Supply & Demand Curve / Production-Possibilities-Frontier / et cetera
• History - Timelines
• Linguistics - International Phonetic Alphabet Chart
• Music - Western Chromatic Scale

I’m probably missing some fields and charts, but these are the major ones that I knew about, when making this list.
