1. The central idea
In ordinary use, knowledge is what a person knows: dependable facts, relationships, methods, or familiarity that can guide thought or action.
In epistemology, the central case is propositional knowledge: knowing that a claim is true—for example, “With net force fixed, doubling mass halves acceleration.” A classical proposal analysed this as justified true belief: the claim is true, the person believes it, and they have adequate reasons. This is useful but incomplete: Gettier-style cases show that a belief can be true and justified through luck, yet still fail to count as knowledge. There is no single universally accepted final analysis.
For this workspace, use the following practical definition:
Knowledge is relatively dependable, appropriately supported content or competence that a person can retain, retrieve, and use to guide accurate reasoning or action in a specified context.
“Relatively dependable” matters. Most empirical knowledge is revisable when better evidence, better measurement, or changed conditions appear. Knowledge is therefore not the same as certainty.
Term-by-term reality mapping: a commute decision
Illustrative situation: A commuter needs to get from home to work on a weekday morning. They have repeatedly found that, when the rail service is operating normally, Route A is usually the most predictable option. Before leaving, they check the official transit app for delays and choose another route if Route A has a disruption.
This is a deliberately conditional example. It does not claim that any transport route is always fastest; the relevant route, time, destination, and service status must be specified.
| Term in the definition | Reality mapping in this situation | What would be missing without it? |
|---|---|---|
| Specified context | Weekday morning; the journey is home-to-work; rail service is operating normally. | “Route A is always fastest” wrongly ignores time, destination, traffic, and disruptions. |
| Relatively dependable | Across comparable trips, Route A has usually been predictable, although not without exceptions. | One unusually quick trip could be luck rather than a dependable pattern. |
| Appropriately supported | The commuter has comparable past journeys, the official service notice, and current app information. | “A friend says it is quick” is information or a reason to investigate, but not yet enough support by itself. |
| Retain | The commuter still remembers the route pattern and the need to check for delays on a later day. | Information that was seen once but is completely forgotten is not presently available as the commuter’s usable knowledge. |
| Retrieve | When leaving home under time pressure, the commuter recalls to check the app. | A fact that cannot be recalled when relevant cannot guide the decision at that moment. |
| Use | After seeing a disruption, the commuter compares alternatives and changes route. | Merely repeating “check the app” without applying the result leaves the content inert. |
| Guide more accurate reasoning | “Route A is normally predictable, but the current delay is a reason to expect a different outcome today.” | Treating a usual pattern as an exceptionless rule is inaccurate reasoning. |
| Guide action | The commuter leaves earlier or selects another route, increasing the chance of arriving on time. | Knowing what would be sensible does not guarantee doing it; fatigue, habits, or self-regulation can still block action. |
| Content | “Under these conditions, Route A is usually the more predictable option.” This is a claim that can be assessed as more or less accurate. | Someone may operate an app without being able to state the relevant claim or its conditions. |
| Competence | The commuter can interpret the app, compare routes, recognise a disruption, and execute a revised plan. | Remembering that an app exists does not establish the ability to use it effectively. |
The example contains both propositional knowledge (knowing that Route A is usually predictable under stated conditions) and knowledge-how (knowing how to check, compare, and adapt a route plan). They support each other, but are not identical.
A learning example using the same terms
Claim: “For material that must be retained after several days, retrieval practice is usually more useful than repeated rereading.”
| Term | Reality mapping |
|---|---|
| Specified context | The target is delayed recall after several days, not merely feeling familiar immediately after study. |
| Relatively dependable | The method is expected to help in many relevant study conditions, not to guarantee improvement for every learner, subject, or implementation. |
| Appropriately supported | Support can include sound comparative evidence and a personal comparison using matched material, immediate tests, delayed tests, error records, and time measures. |
| Retain and retrieve | On a later study session, the learner remembers the distinction and brings it to mind before choosing a method. |
| Use for reasoning | The learner infers that rereading may create familiarity without necessarily improving delayed recall. |
| Use for action | The learner replaces part of a rereading session with recall attempts, checking, and spaced retesting. |
| Content | The conditional claim about retrieval practice and delayed retention. |
| Competence | The ability to design a recall test, record errors, and schedule a later retest. |
The line between knowledge and certainty remains important: a well-supported, condition-sensitive claim can be usable knowledge even when it remains open to revision.
2. Two different ways to classify knowledge
The word type can mean at least two things. Do not mix these axes.
- Philosophical form: What is the object or mode of knowing?
- Learning function: What role does the knowledge play while learning or performing?
The same piece of knowledge may occupy more than one learning category. For example, knowing how to solve an equation includes factual symbols, conceptual relations, and a procedure.
3. Types by philosophical form
| Type | Core question | Example | Boundary |
|---|---|---|---|
| Propositional knowledge (knowing that) | What true claim does the person know? | “Hong Kong is on China’s southern coast.” | A memorised sentence may be a belief or information held by the learner; it counts as knowledge only if it is true and appropriately supported. |
| Knowledge-how / practical knowledge (knowing how) | Can the person perform a method or activity? | “Know how to format a table in Markdown” or “know how to ride a bicycle.” | Being able to recite instructions is not necessarily being able to perform the skill. Philosophers disagree about whether knowledge-how is fully reducible to propositional knowledge. |
| Knowledge by acquaintance / familiarity | Is the person directly familiar with a person, place, object, or experience? | “Know Stan,” “know this street,” or “know the taste of mango.” | Knowing facts about a city is not the same as having visited and being familiar with it. |
“Knowing where,” “knowing when,” and “knowing who” often function grammatically as special cases of knowing a true answer to a question. For example, knowing where the library is can be expressed as knowing the proposition “The library is at X.”
4. Types useful in learning
These categories describe the function of what is known. They are practical distinctions, not a claim that every educational theory uses exactly the same taxonomy.
| Learning type | What it contains | Example | Common false substitute |
|---|---|---|---|
| Factual knowledge | Terms, labels, dates, symbols, and discrete details. | F = ma; the meaning of supply; the definition of working memory. | Recognition of a term without recalling its meaning accurately. |
| Conceptual knowledge | Categories, principles, causal relations, structures, and models. | With net force held constant, a = F/m; price depends on both supply and demand. | A list of facts with no relation connecting them. |
| Procedural knowledge | Steps, techniques, algorithms, and methods for doing something. | Rearrange F = ma to solve for a; use retrieval practice with a delayed test. | Explaining the steps while failing to execute them. |
| Conditional / strategic knowledge | When, why, and under what conditions to select or adapt a method. | Use F = ma only after identifying the relevant net force; use spaced retrieval rather than rereading when long-term retention is the goal. | Applying a familiar method automatically in an unsuitable situation. |
| Metacognitive knowledge | Knowledge about one’s own cognition, task demands, strategies, limits, and monitoring. | “I tend to mistake fluent rereading for durable recall; I should test retrieval after a delay.” | A vague feeling of confidence without a checkable diagnosis. |
Conditional/strategic knowledge is sometimes grouped under procedural or metacognitive knowledge. It is separated here because choosing the right method under the right conditions is a frequent learning bottleneck.
5. Similar concepts that must not be collapsed into knowledge
| Concept | What it is | Difference from knowledge | Example |
|---|---|---|---|
| Data | Recorded observations or measurements. | Data need interpretation and quality checks before they support a claim. | 7/10 on a quiz; a temperature reading. |
| Information | Data or statements organised to communicate something. | Information can be false, irrelevant, unverified, or merely received; it is not automatically knowledge. | A social-media post stating a study method works. |
| Belief | A proposition a person accepts as true. | A belief may be false, unsupported, or correct by luck. Knowledge requires more than confidence. | “More study hours always raise grades.” |
| Opinion | A judgment, preference, or evaluative view. | Some opinions are evidence-based; others express values or tastes and are not true/false in the same way. | “This study plan is better for me.” |
| Evidence | Material that bears on whether a claim is true. | Evidence supports or weakens knowledge claims; it is not automatically the claim itself. | Results from matched practice tests. |
| Truth | Whether a proposition matches the relevant facts or reality. | Truth is a property of a claim; knowledge is a person’s epistemic relation to a true, appropriately supported claim. | “The mass doubled” is true or false in a particular experiment. |
| Understanding | A usable grasp of relationships, mechanisms, and reasons. | Understanding typically organises and uses knowledge; knowledge can be fragmented or recalled without a coherent explanatory model. | Explain why fixed force plus greater mass produces lower acceleration. |
| Skill / ability | Reliable capacity to perform a task. | Skill draws on knowledge but also needs practice, coordination, fluency, and feedback. | Solve several force problems accurately without prompts. |
| Wisdom | Sound judgment about ends, values, trade-offs, and action under uncertainty. | Wisdom uses knowledge but asks what should matter and what should be done. | Choosing a sustainable study plan rather than maximising study hours. |
| Mastery | Reliable, independent, flexible performance in a defined domain. | Mastery normally includes relevant knowledge, but adds stability, independence, transfer, and error correction. | Choose and adapt a physics method in unfamiliar problems, then explain the choice. |
6. One example through the whole map
Claim: “More study time always improves grades.”
- Information: Someone says or writes the sentence.
- Belief: A learner accepts the sentence.
- Evidence: Compare matched learners or materials while measuring study method, rest, prior knowledge, and delayed test results.
- Knowledge claim: “Under specified conditions, more effective study time tends to improve later performance.” The claim must remain open to revision if better evidence disagrees.
- Conceptual knowledge: Study time is only one variable among method, concentration, prior knowledge, feedback, and assessment conditions.
- Procedural knowledge: Set up a small comparison with matched material and immediate plus delayed retrieval tests.
- Conditional/strategic knowledge: Use retrieval practice and spacing if long-term retention—not merely immediate familiarity—is the target.
- Understanding: Explain why extra time spent rereading can create fluency without improving delayed recall.
- Mastery: Independently evaluate several new learning claims, choose valid measures, detect confounds, and revise conclusions.
7. A short test for a knowledge claim
For any proposed item of knowledge, ask:
- What exactly is claimed? State it in a sentence.
- What kind is it? Fact, concept/model, procedure, conditional strategy, metacognitive knowledge, or acquaintance?
- What makes it dependable here? Direct observation, reliable source, valid reasoning, repeated performance, or another form of evidence?
- What are its conditions and limits? When would it not apply?
- What would change my mind? Name possible counterevidence or a measurement error.
This test does not solve every philosophical dispute about knowledge. It does prevent treating exposure, confidence, a single source, or one successful attempt as conclusive knowledge.
Current boundary for the learner
This note is an explanation provided by the LLM. It records no independent learner retrieval, comparison, application, or critique of these distinctions yet. The smallest meaningful next action is to classify one everyday statement as data, information, belief, evidence, knowledge claim, understanding, or skill—and state why the neighbouring categories do not fit.
