Map of All Known Knowledge
16 comments
Librarians have systems that can classify every published book. And scientific publishers can classify every paper. Those don't add up to a complete classification of all human knowledge, but it's a substantial fraction of it.
If you skim the high-level book categories at https://en.wikipedia.org/wiki/List_of_Dewey_Decimal_classes, you may conclude this is is beyond a lifetime's work.

Okay I got it . But do we have any best possible classification system or map . That is most complete.
A map which has tried to capture totality of all known human knowledge without leaving anything significant.
I want this so I am not unaware of any field of knowledge. Atleast any significant feild of knowledge
Practically Best possible .
Thank you sir for your response

Mmhmm. A talented cataloger in a research library understands where the 'fuzz' in these systems is - where the margins intersect - and they have a process for helping systematize those classifications in a way that they can socialize with other librarians across the world. (If nobody has ever cataloged a particular book before... your record is probably going into OCLC WorldCat and other people will borrow the output of your thinking process later... making things more and more definitive.)
I once read that if you tried to read every Wikipedia article for 12 hours a day, it would take you about 42 years to finish—assuming no new content gets added along the way.

MIT OpenCourseWare has a series of lectures on AI by Marvin Minsky and in one lecture he describes two projects in need of each other but were drifting apart that aimed to keep a beat on knowledge.
You may want to trace the history of librarianship.

As you suggest I read about librarianship
And I got some maps
But a question comes in mind that which map should I trust For my needs . Which map has that quality.

There is no map. Because knowledge and the relations between concepts are not static. Its a dynamical ever growing system.
There is no limit at all for the expanses of human knowledge. Including that every single individual out of all the billions of people on Earth has some knowledge that nobody else has.
> It is generally understood that all the knowledge humanity currently possesses is finite and organized into distinct areas.
No, this is not generally understood, because it is not true.
You will go insane if you try to classify or map all human knowledge.

Okay . As far I have learned is that everything all humanity knows at any specific point of time is finite and growing rapidly.
Collective human knowledge is finite at any moment and growing and divided into many areas for convenience . We have disciplines such as physics, maths etc.
Yes it is enormous and it seems to Practically extremely difficult to make such a map.
I understood your point

This is a deep question. Many a great mind in history have thought about how to organize all of the world's knowledge systematically.

Honestly, none of the lists are satisfyingly comprehensive. Like a fractal, you can zoom into any one subject, and it branches into more and more specific categories. Wikipedia has various lists and outlines that come closer to what you describe.

Yes, I understand, like you I have the same question and desire for a map of all knowledge. It relates to library science, how to organize all books on all subjects; and in general, the aim of academia, an organized system to learn, research, and teach all subjects. On the dark side, it relates to Seeing Like a State, the quest for dominion over the entire world and everything in it. There is the concept of legibility, the limits of what you can know (see/measure/quantify/understand) and the vast unknown beyond it. So we must accept that the map can never be complete. But we can try!
You'll have to create your own comprehensive outline and classification system. I'd start with an encyclopedic overview.
> Below is a summary of the world's knowledge, in the form of an outline. Each subject in turn links to an outline that summarizes that subject.
https://en.wikipedia.org/wiki/Wikipedia:Contents/Outlines
And all academic subjects.
> Academic disciplines are conventionally divided into the humanities (including philosophy, languages, art and cultural studies), the natural sciences (such as physics, chemistry, and biology); the formal sciences like mathematics and computer science; and the social sciences
https://en.wikipedia.org/wiki/Outline_of_academic_discipline...
Getting closer, but as you can see, there are significant holes. Some of that can be improved by filling in the details. But it becomes clear that there is a cultural bias in these outlines and lists, of what subjects are worthy of study in academia, or what to include in an encyclopedia. Beyond that, for example, there is oral or even non-verbal knowledge and understanding passed from one generation to the next, or from teacher to student, in world cultures large and small, such as musical or religious/mystical traditions.
What's also lacking is a classification system, like the Dewey Decimal or Library of Congress system. Again, you'll have to come up with your own organization, because I'm sure you'll find that none of the existing systems are satisfactory. Here's a good start.

A related question is how to map and classify all digital objects.

Also, one can think about semantic networks and knowledge graphs. The systems of organization described so far assume that everything can be represented in a hierarchical list, a limited form of tree structure. However, in the human brain and in the real world, relationships between concepts and things form graph structures.
What kind of classification system would be able to better represent graphs rather than lists of lists?
I wish you good luck in your quest. One of my favorite intellectuals is Gottfried Wilhelm Leibniz, considered a "polymath" or "Renaissance man", who seeked to systematically organize all of human knowledge. See, for example: Alphabet of human thought; Characteristica universalis; and Calculus ratiocinator. His explorations and concepts were very influential in the invention of computers.

What about private knowledge such as my account password? I think you need to first rigorously define what you mean by "knowledge" and "subject".
Start with the library of congress classification system. It'll get you 90 percent of the way there for 10% of the effort.
(Classification systems are very much an information science topic... and they're pretty damn important. Along those same lines - you'll want to think carefully and critically about what is seen as canonical knowledge, and what's "in" those fields, versus what is perceived as "utter crackpot bullshit" that nobody takes seriously. The fields you've mentioned ALL have a significant amount of bleed at the edges - where does math become mathematical physics and then 'really physics' ... it's just not that easy.)
Fanboy comment: just google Eugene Garfield. Have fun!

I am a high school student, and I have been thinking about the way knowledge is structured. In schools and universities, we study subjects such as mathematics, physics, biology, and many others. This has led me to wonder: exactly how many subjects exist in total? It is generally understood that all the knowledge humanity currently possesses is finite and organized into distinct areas. I am interested in knowing whether there exists a comprehensive list, table, map, or conceptual framework that captures the entire body of known human knowledge without excluding anything. In other words, I am seeking a complete and exhaustive classification of all subjects, such that no area of knowledge is left unaccounted for. I wish to ensure that I am not unaware of any subject.
