What is Knowledge?

Students explore the traditional definition of knowledge as justified true belief and examine Gettier problems. They will evaluate the criteria required to claim that one truly 'knows' something.

TL;DR:This topic introduces the foundational JTB (Justified True Belief) model, which has served as the standard definition of knowledge since Plato. Students examine the three necessary and sufficient conditions for knowledge: a person must believe the proposition, the proposition must be true, and there must be sufficient justification. This is a critical starting point in the H2 Knowledge and Inquiry syllabus as it establishes the vocabulary for all subsequent epistemological discussions.

About This Topic

This topic introduces the foundational JTB (Justified True Belief) model, which has served as the standard definition of knowledge since Plato. Students examine the three necessary and sufficient conditions for knowledge: a person must believe the proposition, the proposition must be true, and there must be sufficient justification. This is a critical starting point in the H2 Knowledge and Inquiry syllabus as it establishes the vocabulary for all subsequent epistemological discussions.

Students will also encounter the famous Gettier problems, which challenge the sufficiency of JTB by presenting cases of 'epistemic luck.' In the Singapore context, where students are often high achievers focused on 'correct' answers, this topic is vital for shifting their mindset toward critical evaluation of the nature of certainty. This topic comes alive when students can physically model the patterns of justification through collaborative problem solving and thought experiments.

Key Questions

1. What distinguishes knowledge from mere belief?
2. Is justification always necessary for knowledge?
3. How do Gettier cases challenge traditional epistemology?

Watch Out for These Misconceptions

Common Misconception

Believing something very strongly makes it true.

What to Teach Instead

Truth is an external condition independent of the intensity of belief. Peer discussion helps students see that two people can believe opposite things with equal conviction, yet both cannot be true simultaneously.

Common Misconception

Justification must be 100% certain to count as knowledge.

What to Teach Instead

Most epistemologists accept 'fallibilism,' where justification can be strong without being infallible. Active modeling of different levels of evidence helps students understand the threshold for 'sufficient' justification.

Active Learning Ideas

Inquiry Circle

The Gettier Case Workshop

Small groups are given different 'Gettier-style' scenarios and must identify why the subject has a justified true belief that fails to count as knowledge. They then present their findings to the class to find common themes in these failures.

Formal Debate

Is Truth Objective?

Students are split into teams to debate whether truth is an absolute property of a proposition or if it is relative to cultural or personal frameworks. This helps them distinguish between 'truth' and 'belief' in the JTB triad.

Think-Pair-Share

Justification Scales

Students independently list three things they 'know' and then pair up to rank the strength of their justifications. They must decide at what point a justification becomes 'sufficient' for the claim to be called knowledge.

Frequently Asked Questions

What is the tripartite definition of knowledge?

It is the traditional view that knowledge consists of three components: Justification, Truth, and Belief (JTB). For a subject to know a proposition, they must believe it, it must be true, and they must have a good reason for believing it. This framework helps students categorize different types of claims they encounter in their studies.

Why are Gettier problems important for JC students?

Gettier problems show that luck can sometimes lead to a justified true belief. For JC students, this encourages a deeper level of critical thinking beyond just memorizing facts. It teaches them to look for 'hidden' flaws in reasoning and to appreciate the complexity of defining what we truly know.

How can active learning help students understand JTB?

Active learning strategies like thought experiments and peer critiques allow students to test the JTB conditions in real-time. Instead of just reading about Gettier cases, students who construct their own scenarios learn to identify the exact point where justification breaks down. This hands-on application makes abstract philosophical concepts more concrete and memorable.

Does KI require students to find a 'perfect' definition of knowledge?

No, the goal is not to find a single perfect answer but to understand the ongoing debate. The SEAB syllabus rewards students who can evaluate the strengths and weaknesses of various definitions. Engaging in structured debates helps students practice this evaluative skill by forcing them to defend and critique different epistemological positions.
