the Knowledge 

The Knowledge is the in-depth study of London street routes and places of interest that taxicab-drivers must complete to obtain a licence to operate a black cab. It was instigated in 1851, and has changed little since.

It is the world's most demanding training course for taxicab-drivers; and applicants will usually need at least 12 'Appearances' (attempts at the final test), after preparation averaging 34 months, to pass the examination.

Your mate doesn't stand a chance to pass the Knowledge no matter how hard he tries!

on the knowledge 

UK Slang. Mostly used by taxi drivers when referring to the way they drive, using knowledge of the area they have gained, rather than maps or GPS.

"this taxi driver rules, he's on the knowledge"

absorb the knowledge 

(verb) to flip somebody off while saying "absorb the knowledge." Usually said when you disagree with someone or want them to know you're not interested in what they're saying.

Person 1: "hey man can give you give me a ride home?"

Person 2: "how about you absorb the knowledge."

"She knocked on my door asking to get back together. I told her to absorb the knowledge."

"I wish I could tell my boss to absorb the knowledge."

The 4 Axes of the Knowledge Spectrum

An expanded model adding two crucial dimensions to the basic framework. Axis 1: A Priori-A Posteriori (reason vs. experience). Axis 2: Propositional-Procedural (that vs. how). Axis 3: Personal-Communal (knowledge held by individuals vs. knowledge stored in communities). Axis 4: Explicit-Tacit (knowledge you can state vs. knowledge you can't articulate). These four axes create sixteen knowledge types. Scientific knowledge is a posteriori, propositional, communal (scientific community knows), explicit (published). Cultural knowledge is a posteriori, procedural (knowing how to navigate a culture), communal, tacit (you just know how things work). The 4 Axes reveal that debates about knowledge often confuse these dimensions—dismissing tacit knowledge because it's not explicit, or communal knowledge because it's not personal.

The 4 Axes of the Knowledge Spectrum "You say you can't prove what you know. The 4 Axes ask: what kind of knowledge? Tacit knowledge can't be proved—that's its nature. Procedural knowledge is shown, not stated. Communal knowledge is distributed, not owned. The axes help you see that demanding explicit propositional proof for all knowledge is like demanding a fish to climb a tree."

The 6 Axes of the Knowledge Spectrum

A comprehensive model adding dimensions of certainty and access. Axis 1: A Priori-A Posteriori. Axis 2: Propositional-Procedural. Axis 3: Personal-Communal. Axis 4: Explicit-Tacit. Axis 5: Certain-Fallible (knowledge that can't be wrong vs. knowledge that might be mistaken). Axis 6: Direct-Inferential (known directly vs. known through reasoning). These six axes generate sixty-four knowledge positions. Mathematical knowledge is a priori, propositional, personal (when learned), explicit, certain (in ideal), inferential (proved). Perceptual knowledge is a posteriori, propositional, personal, explicit (usually), fallible, direct. The 6 Axes reveal that different kinds of knowledge have different epistemic statuses—certainty isn't the same for all.

The 6 Axes of the Knowledge Spectrum "You demand certainty. The 6 Axes ask: what kind of knowledge? Math can be certain (maybe). Perceptual knowledge can't—that's not its function. Certainty is a feature of some knowledge types, not a requirement for all. The axes help you see that demanding certainty from empirical knowledge is asking for the wrong thing."

The 8 Axes of the Knowledge Spectrum

A detailed model adding dimensions of subject matter and value. Axis 1: A Priori-A Posteriori. Axis 2: Propositional-Procedural. Axis 3: Personal-Communal. Axis 4: Explicit-Tacit. Axis 5: Certain-Fallible. Axis 6: Direct-Inferential. Axis 7: Empirical-Conceptual (knowledge of facts vs. knowledge of concepts/meanings). Axis 8: Instrumental-Intrinsic (knowledge for use vs. knowledge for its own sake). These eight axes create 256 knowledge positions. Scientific knowledge is a posteriori, propositional, communal, explicit, fallible, inferential, empirical, both instrumental and intrinsic. Philosophical knowledge is often a priori, propositional, personal (though debated), explicit, fallible (or certain in some views), inferential, conceptual, intrinsic. The 8 Axes demonstrate that knowledge isn't just about truth—it's about purpose, subject, and value.

The 8 Axes of the Knowledge Spectrum "You say knowledge is just facts. The 8 Axes ask: facts about what? Empirical facts (science) or conceptual facts (philosophy)? Facts for use (engineering) or for understanding (pure math)? The axes show that 'facts' are as varied as knowledge itself. Treating all knowledge as empirical facts for use is like treating all food as protein bars—nutritionally reductive and spiritually empty."
