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."

The 16 Axes of the Knowledge Spectrum

The ultimate model, adding the final dimensions of scope, certainty, and the epistemic subject. Building on the 12 Axes, we add: Axis 13: Defeasible-Indefeasible (knowledge can be overturned vs. immune to revision). Axis 14: Absolute-Relative (knowledge holds for all vs. relative to framework). Axis 15: Human-Transhuman (knowledge accessible to humans vs. beyond human capacity). Axis 16: Finite-Infinite (knowledge is bounded vs. potentially infinite). These sixteen axes generate 65,536 potential positions—enough to capture every epistemological theory, every conception of knowledge, every debate about what it means to know. The 16 Axes of the Knowledge Spectrum reveal that knowledge is not a simple concept but a multidimensional space of possibilities. The 16 Axes don't tell you which conception of knowledge is correct—they give you a language for understanding what any knowledge claim involves, what it assumes, and how it relates to other kinds of knowing. They are the map of the space of human understanding—the periodic table of epistemology itself.

The 16 Axes of the Knowledge Spectrum "You want to know what knowledge is. The 16 Axes answer: it depends. For a scientist, knowledge is a posteriori, propositional, communal, explicit, fallible, inferential, empirical, instrumental, justified, externalist, social, particular, defeasible, relative, human, finite. For a mathematician, it's a priori, propositional, personal, explicit, certain, inferential, conceptual, intrinsic, justified, internalist, individualist, universal, indefeasible, absolute, human, infinite. For a mystic, it's experiential, procedural/tacit, personal, tacit, certain (to them), direct, both, intrinsic, justified by experience, externalist (experience is reliable), individualist, particular, defeasible (to others), relative, human, finite. Same word, sixteen axes of difference. The axes don't define knowledge—they give you the language to ask what anyone means by it. And that's the most profound knowledge of all."

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 College of Knowledge 

The College of Knowledge is none other than the astounding institute of College of Charleston, which is located in historic downtown Charleston, SC.

While it is a small school, it is in the heart of a gorgeous city full of historic architecture, including many houses and churches, and is a quick drive to many beaches and parks. The College of Charleston is a liberal arts school with a very dynamic student body (just around two-thirds female) and a competitive athletic program.

The College of Knowledge is the best college in the country. Students are fun and exciting, the women are gorgeous, the sports are successful, and you can't beat Charleston, SC.
