Grok

Template:Short description Template:Italic title Template:Use dmy dates Grok (Template:IPAc-en) is a neologism coined by the American writer Robert A. Heinlein for his 1961 science fiction novel Stranger in a Strange Land. While the Oxford English Dictionary summarizes the meaning of grok as "to understand intuitively or by empathy, to establish rapport with" and "to empathize or communicate sympathetically (with); also, to experience enjoyment", Heinlein's concept of a human who comes to Earth in early adulthood after being born on the planet Mars is far more nuanced, with critic Istvan Csicsery-Ronay Jr. observing that "the book's major theme can be seen as an extended definition of the term." The concept of grok garnered significant critical scrutiny in the years after the book's initial publication. The term and aspects of the underlying concept have become part of communities such as computer science.

Descriptions in Stranger in a Strange Land

Critic David E. Wright Sr. points out that in the 1991 "uncut" edition of Stranger, the word grok "was used first without any explicit definition on page 22" and continued to be used without being explicitly defined until page 253 (emphasis in original). He notes that this first intentional definition is simply "to drink", but that this is only a metaphor "much as English 'I see' often means the same as 'I understand'". Critics have bridged this absence of explicit definition by citing passages from Stranger that illustrate the term. A selection of these passages follows:

Grok means "to understand", of course, but Dr. Mahmoud, who might be termed the leading Terran expert on Martians, explains that it also means, "to drink" and "a hundred other English words, words which we think of as antithetical concepts. 'Grok' means all of these. It means 'fear', it means 'love', it means 'hate' — proper hate, for by the Martian 'map' you cannot hate anything unless you grok it, understand it so thoroughly that you merge with it and it merges with you — then you can hate it. By hating yourself. But this implies that you love it, too, and cherish it and would not have it otherwise. Then you can hate — and (I think) Martian hate is an emotion so black that the nearest human equivalent could only be called mild distaste.

Grok means "identically equal". The human cliché "This hurts me worse than it does you" has a distinctly Martian flavor. The Martian seems to know instinctively what we learned painfully from modern physics, that observer acts with observed through the process of observation. Grok means to understand so thoroughly that the observer becomes a part of the observed — to merge, blend, intermarry, lose identity in group experience. It means almost everything that we mean by religion, philosophy, and science and it means as little to us as color does to a blind man.

The Martian Race had encountered the people of the fifth planet, grokked them completely, and had taken action; asteroid ruins were all that remained, save that the Martians continued to praise and cherish the people they had destroyed.

All that groks is God.

Etymology

Robert A. Heinlein originally coined the term grok in his 1961 novel Stranger in a Strange Land as a Martian word that could not be defined in Earthling terms, but can be associated with various literal meanings such as "water", "to drink", "to relate", "life", or "to live", and had a much more profound figurative meaning that is hard for terrestrial culture to understand because of its assumption of a singular reality.

According to the book, drinking water is a central focus on Mars, where it is scarce. Martians use the merging of their bodies with water as a simple example or symbol of how two entities can combine to create a new reality greater than the sum of its parts. The water becomes part of the drinker, and the drinker part of the water. Both grok each other. Things that once had separate realities become entangled in the same experiences, goals, history, and purpose. Within the book, the statement of divine immanence verbalized among the main characters, "thou art God", is logically derived from the concept inherent in the term grok.

Heinlein describes Martian words as "guttural" and "jarring". Martian speech is described as sounding "like a bullfrog fighting a cat". Accordingly, grok is generally pronounced as a guttural gr terminated by a sharp k with very little or no vowel sound (a narrow IPA transcription might be ). William Tenn suggests Heinlein in creating the word might have been influenced by Tenn's very similar concept of griggo, introduced in Tenn's 1949 story Venus and the Seven Sexes. In his later afterword to the story, Tenn says Heinlein considered such influence "very possible".

Adoption and modern usage

In computer programmer culture

Uses of the word in the decades after the 1960s are more concentrated in computer culture, such as an InfoWorld columnist in 1984 imagining a computer saying, "There isn't any software! Only different internal states of hardware. It's all hardware! It's a shame programmers don't grok that better."

The Jargon File, which describes itself as "The Hacker's Dictionary" and has been published under that name three times, puts grok in a programming context:

The entry existed in the very earliest forms of the Jargon File in the early 1980s.

The 2005 book Perl Best Practices defines grok as understanding a portion of computer code in a profound way. It goes on to suggest that to re-grok code is to reload the intricacies of that portion of code into one's memory after some time has passed and all the details of it are no longer remembered. In that sense, to grok means to load everything into memory for immediate use. It is analogous to the way a processor caches memory for short term use, but the only implication by this reference was that it was something a human (or perhaps a Martian) would do.

Examples of usage

A typical tech usage from the Linux Bible characterizes the Unix software development philosophy as "one that can make your life a lot simpler once you grok the idea".

The 1994 book Cyberia covers its use in this subculture extensively:

• The main web page for cURL, an open source tool and programming library, describes the function of cURL as "cURL groks URLs".
• The keystroke logging software used by the NSA for its remote intelligence gathering operations is named GROK.
• One of the most powerful parsing filters used in Elasticsearch software's logstash component is named grok.
• A reference book by Carey Bunks on the use of the GNU Image Manipulation Program is titled Grokking the GIMP.
• The generative artificial intelligence chatbot developed by xAI is named Grok.

In counterculture

• Tom Wolfe, in his 1968 book The Electric Kool-Aid Acid Test, describes a character's thoughts during an acid trip: "He looks down, two bare legs, a torso rising up at him and like he is just noticing them for the first timeTemplate:Nbs... he has never seen any of this flesh before, this stranger. He groks over thatTemplate:Nbs..."

• In his counterculture Volkswagen repair manual, How to Keep Your Volkswagen Alive: A Manual of Step-by-Step Procedures for the Compleat Idiot (1969), dropout aerospace engineer John Muir instructs prospective used VW buyers to "grok the car" before buying.

• The word was used numerous times by Robert Anton Wilson in his works The Illuminatus! Trilogy and Schrödinger's Cat Trilogy. For instance, in The Eye in the Pyramid, volume one of Illuminatus:

I caught the references to Aristotle, the old man of the tribe with his unfortunate epistemological paresis, and also to that feisty little lady I always imagine is really the lost Anastasia, but I still didn’t grok. “What do you mean?” I asked (...)

• And in The Trick Top Hat, volume two of Schrödinger's Cat:

Williams went on. "You've got to think of time ripples, as well as space ripples, to grok the quantum world. ..."
