ⓘ Encyclopedic knowledge

To have encyclopedic knowledge is to have "vast and complete" knowledge about a large number of diverse subjects. A person having such knowledge is called a human encyclopedia or a walking encyclopedia.

It is no longer considered realistic, or feasible, for any one person to be truthfully described as having encyclopedic knowledge. The concept has been subsumed into the discourses on the production of knowledge and artificial intelligence. Instead, we are now preoccupied with knowledge bases distributed as software or web services.

The concept of encyclopedic knowledge was once attributed to exceptionally well-read or knowledgeable persons such as Plato, Aristotle, Hildegard von Bingen, Leonardo da Vinci, Immanuel Kant, or G. W. F. Hegel. Tom Rockmore described Hegel, for example, as a polymath and "a modern Aristotle, perhaps the last person to know everything of value that was known during his lifetime." Such persons are generally described as such based on their deep cognitive grasp of multiple and diverse fields of inquiry - an intellectually exceptional subset of philosophers who might also be differentiated from the multi-talented, the genius, or the "Renaissance man."


1. References in popular culture

The idea of encyclopedic knowledge has made many appearances in popular culture, being especially widespread in detective fiction. In 1887, Sir Arthur Conan Doyle introduced his fictional master sleuth, Sherlock Holmes, who applied his keen deductive acumen and prodigious range of knowledge to solve his cases. Encyclopedia Brown is a series of books by Donald J. Sobol featuring the adventures of boy detective Leroy Brown, nicknamed "Encyclopedia" for his intelligence and range of knowledge that was first published in 1963.

One of the most celebrated is the fictional Hitchhikers Guide to the Galaxy by the late Douglas Adams which began its evolution through numerous mediums as a British radio program in 1978. In 2004, NPR contributor A.J. Jacobs published The Know-It-All, about his experience reading the entire Encyclopædia Britannica from start to finish.


2. Domain-specific

While deep encyclopedic knowledge across numerous fields of inquiry by a single person is no longer feasible, encyclopedic knowledge within a field of inquiry or topic has great historical precedent and is still often ascribed to individuals. For example, it has been said of Raphael Lemkin that "his knowledge of the logic behind the Nazi war machine was encyclopedic."

In 1900, Alexander Graham Bell, who set out to read the entire Encyclopædia Britannica himself, served as the second president of the National Geographic Society and declared the Society should cover "the world and all that is in it." While this goal sounds all-encompassing, it is in fact a statement towards comprehensive geographic knowledge, meaning the scope of the National Geographic Societys enterprise should attempt to be terrestrially unbounded.

In an era of specialization, be it academic or functional or epistemological, obtaining domain-specific encyclopedic knowledge as an expert is typically celebrated and often rewarded by institutions in modern society.



Edward Said, in his seminal postcolonial work, Orientalism, examines the encyclopedic endeavor in great detail, revealing it to be an historically hegemonic enterprise. Orientalists "unremitting ambition was to master all of a world, not some easily delimited part of it such as an author or a collection of texts."

Tim Chambers, an early Wikipedian who proposed the name "Wikipedia", has a page of historical interest in the Wikimedia archives entitled "The Value of Encyclopedic Knowledge" in which he describes a new model for growing encyclopedic knowledge "powered by numerous scholars around the world." The idea of encyclopedic knowledge being re-constellated as a community of knowledge is central to the theory of Connectivism as established by George Siemens and Stephen Downes.
