Knowledge: Understanding Truth and Belief
When people talk about knowledge, they don't always mean the same thing. They might be talking about:
Different Kinds of Knowledge:
- Knowing how to do something (skills, like riding a bike)
- Being acquainted with someone or something (recognizing a face)
- Knowing that something is true (facts and truths)
Philosophers are mainly interested in this third type—philosophical knowledge, or knowing facts.
What Does Philosophy Say About Knowledge?
Epistemology (eh-pis-TOH-loh-jee) is the branch of philosophy that studies knowledge. Philosophers studying knowledge ask questions like:
> How do we come to know things?
> What is knowledge, exactly?
> Can we actually really know anything?
The Problem of Knowledge
Philosophers have identified several difficult questions about knowledge:
1. How Do We Know?
How do our senses give us knowledge? Are our senses reliable? How does memory preserve knowledge?
2. Can We Ever Be Certain?
Philosophers have different views:
- Skeptics: Question whether we can ever know anything with certainty
- Dogmatists: Believe we can know things with absolute certainty
- Evidentialists: Think we can know things when we have good evidence
3. What Is Required for Knowledge?
What must be true for someone to truly know something?
- Must they believe it?
- Must it be true?
- Must they have good reasons?
- Can they be wrong and still count as knowing?
The Classic Definition (Plato - 4th Century BCE)
Knowledge is justified true belief. This means:
- 1. You must believe it
- 2. It must be true
- 3. You must have good reasons (justification)
The Gettier Problem
In the 1960s, philosopher Edmund Gettier showed this definition isn't perfect by creating famous counterexamples—the "Gettier problem." Sometimes, people have justified true belief without actually having "real knowledge."
Key Kinds of Knowledge:
A Priori vs. A Posteriori:
- A priori knowledge: You can know this without experience, just by thinking (like "1+1=2")
- A posteriori knowledge: You need to experience something to learn this (like "water boils at 100°C")
Scientific Knowledge:
- Scientists propose theories and test them
- Strong evidence can lead to well-confirmed knowledge
- But even scientific knowledge is sometimes revised
Intuitive Knowledge:
- Some things we "just know" without much reasoning
- Like recognizing a face or feeling pain
- Philosophy asks: Is this really knowledge? Or is it something else?
Moral Knowledge:
- Do we know right from wrong?
- What is beauty or justice?
- Can we know these things without scientific proof?
Everyday vs. Philosophical Knowledge:
Everyday meaning: "I know how to play basketball" (skill/knowledge)
Philosophical meaning: "I know that 2+2=4" (justified true belief)
Why This Matters:
- Understanding knowledge helps us know what we can trust
- Recognizing what we don't know is as important as knowing what we do
- Questions about truth and belief affect science, religion, and everyday life
Questions Philosophers Ask:
- Can computers ever really "know" anything?
- How does language help or limit knowledge?
- What is the relationship between knowledge and belief?
- Can we trust our memories?
- Are there universal truths across all cultures?
Key Insight:
Philosophy shows us that "knowing" isn't automatic. It requires careful questioning, evidence, and reflection. The more we examine what knowledge really is, the more we appreciate how important it is to know what we can truly say we understand.
