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 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."

The 2 Axes of the Knowledge Spectrum

A foundational model for understanding the nature of knowledge along two fundamental dimensions. The first axis runs from A Priori Knowledge (knowledge independent of experience—math, logic, conceptual truths) to A Posteriori Knowledge (knowledge dependent on experience—empirical facts, scientific observations). The second axis runs from Propositional Knowledge (knowing that—facts, information) to Procedural Knowledge (knowing how—skills, abilities, practices). These two axes create four basic knowledge types: a priori-propositional (mathematical truths), a priori-procedural (knowing how to reason), a posteriori-propositional (scientific facts), a posteriori-procedural (knowing how to ride a bike). The model reveals that "knowledge" isn't one thing—it's a family of cognitive achievements with different sources and different forms.

The 2 Axes of the Knowledge Spectrum "You say you know it. The 2 Axes ask: know that or know how? Know from reason or from experience? Knowing that 2+2=4 is very different from knowing how to ride a bike. Same word, different kinds. The axes help you see that 'knowledge' covers a lot of territory—and treating all knowledge like math is a category error."
