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."
