Epistemology Course
This Epistemology Course gives you a rigorous, systematic command of how knowledge works — from classical justification theories to cutting-edge debates about AI, misinformation, and epistemic injustice. You will engage with the arguments that have shaped philosophy for centuries and develop the analytical tools to evaluate them critically. If you think carefully about what you know and why, this course is built for you.
What you will learn:
You will master the core theories of knowledge and justification, including foundationalism, coherentism, and reliabilism, and learn exactly why the Gettier problem forced philosophers to rethink the standard definition of knowledge. You will examine the major sources of knowledge — perception, reason, memory, testimony, and intuition — and assess the reliability of each. The course covers skeptical challenges from Descartes to contemporary brain-in-a-vat scenarios, along with the most compelling responses philosophers have developed. You will also explore social and virtue epistemology, epistemic injustice, and the epistemology of science. Finally, you will apply these frameworks to urgent contemporary issues including misinformation, digital environments, and AI-generated information.

Chapter 1HideHide detailsSee detailsWhat Is Epistemology?
What Is Epistemology?
Lesson 1 • Defining Knowledge and Belief
Distinguishes knowledge from mere belief and opinion using classical criteria. Anchors the chapter by establishing the primary object of epistemological inquiry.
Lesson 2 • Core Questions of Epistemology
Maps the fundamental questions: What can we know? How do we know it? What are knowledge's limits? Frames the intellectual agenda for the entire course.
Lesson 3 • Historical Origins and Key Figures
Traces epistemology from ancient Greek inquiry through early modern philosophy. Provides historical context that explains why current debates take their present form.
Lesson 4 • Epistemology Within Philosophy
Positions epistemology relative to metaphysics, logic, and ethics. Shows students how epistemological commitments shape other philosophical domains.
Chapter 2HideHide detailsSee detailsSources of Knowledge
Sources of Knowledge
Lesson 1 • Memory as an Epistemic Source
Investigates memory's role in preserving and transmitting knowledge over time. Addresses reliability concerns and the reconstructive nature of memory.
Lesson 2 • Intuition and Introspection
Assesses intuition and introspective access as contested epistemic sources. Connects to debates about self-knowledge and philosophical methodology.
Lesson 3 • Testimony and Social Knowledge
Explores how knowledge is transmitted through the reports of others. Introduces reductionist and anti-reductionist positions on testimonial justification.
Lesson 4 • Reason and A Priori Knowledge
Examines knowledge independent of sensory experience, including mathematics and logic. Contrasts rationalist and empiricist accounts of a priori justification.
Lesson 5 • Perception and Sensory Experience
Analyzes how sensory experience generates beliefs and under what conditions those beliefs count as knowledge. Introduces the reliability problem central to later chapters.
Chapter 3HideHide detailsSee detailsTheories of Justification
Theories of Justification
Lesson 1 • Reliabilism and Process Theories
Presents reliabilism as an externalist account linking justification to reliable cognitive processes. Introduces process reliabilism and the generality problem.
Lesson 2 • Internalism vs. Externalism
Directly contrasts internalist and externalist conceptions of justification. Prepares students to evaluate which framework best handles real epistemic cases.
Lesson 3 • Coherentism
Analyzes the view that justification arises from coherence among a system of beliefs. Addresses the isolation objection and compares coherentism with foundationalism.
Lesson 4 • Foundationalism
Examines the claim that justified beliefs rest on a foundation of basic, non-inferentially justified beliefs. Evaluates classical and modest versions of the view.
Lesson 5 • The Structure of Justification
Introduces the regress problem and explains why it motivates competing structural theories. Establishes the conceptual framework for evaluating all justification theories.
Chapter 4HideHide detailsSee detailsThe Gettier Problem and Its Aftermath
The Gettier Problem and Its Aftermath
Lesson 1 • Knowledge-First and Contextualist Responses
Introduces Williamson's knowledge-first approach and contextualist strategies as radical alternatives. Previews themes developed in later chapters.
Lesson 2 • The Traditional Definition Revisited
Reviews the justified true belief account before introducing its refutation. Ensures students understand what is at stake before examining counterexamples.
Lesson 3 • Gettier's Original Counterexamples
Presents Gettier's two original cases and explains why they defeat the JTB account. Students practice identifying the structural features that generate Gettier cases.
Lesson 4 • Causal and Reliability Responses
Examines causal theories and reliability-based responses to Gettier. Connects this section to reliabilism introduced in the previous chapter.
Lesson 5 • No-False-Lemma and No-Defeater Responses
Evaluates responses that add conditions blocking false intermediate steps or defeaters. Assesses whether these additions successfully restore the definition.
Chapter 5HideHide detailsSee detailsTruth, Belief, and Knowledge Norms
Truth, Belief, and Knowledge Norms
Lesson 1 • Epistemic Akrasia and Rationality
Investigates cases where agents believe against their own evidence or higher-order judgments. Connects belief norms to broader theories of rationality.
Lesson 2 • Norms of Assertion
Examines the knowledge norm of assertion and competing weaker norms. Bridges epistemology and philosophy of language for practical application.
Lesson 3 • Theories of Truth
Surveys correspondence, coherence, pragmatist, and deflationary theories of truth. Grounds subsequent discussion of truth as a condition on knowledge.
Lesson 4 • Degrees of Belief and Bayesianism
Introduces credences, probability, and Bayesian updating as a formal framework for rational belief. Extends the course beyond binary belief to graded attitudes.
Lesson 5 • Norms of Belief
Analyzes truth, justification, and knowledge norms for belief. Connects normative epistemology to the structural theories covered in Chapter 3.
Chapter 6HideHide detailsSee detailsSkepticism and Its Challenges
Skepticism and Its Challenges
Lesson 1 • Closure, Transmission, and Abductivism
Examines closure-denial strategies and inference-to-the-best-explanation responses to skepticism. Provides students with a toolkit for evaluating anti-skeptical arguments.
Lesson 2 • Forms and History of Skepticism
Surveys ancient Pyrrhonism, Academic skepticism, and Cartesian doubt. Establishes the historical depth and variety of skeptical positions.
Lesson 3 • Moorean and Commonsense Responses
Presents Moore's proof of the external world and commonsense philosophy as anti-skeptical strategies. Evaluates the philosophical force of these responses.
Lesson 4 • Contextualism and Relevant Alternatives
Explains how contextualism and relevant alternatives theory defuse skeptical arguments by relativizing knowledge standards. Connects to Gettier responses from the prior chapter.
Lesson 5 • Skeptical Scenarios and Arguments
Reconstructs the evil demon, brain-in-a-vat, and dream arguments as formal challenges. Students learn to identify the logical structure driving each scenario.
Chapter 7HideHide detailsSee detailsSocial and Virtue Epistemology
Social and Virtue Epistemology
Lesson 1 • Social Epistemology Foundations
Analyzes how social structures, institutions, and practices shape collective knowledge. Introduces the division of cognitive labor and peer disagreement.
Lesson 2 • Virtue Epistemology Foundations
Introduces intellectual virtues as stable character traits that reliably produce knowledge. Distinguishes virtue reliabilism from virtue responsibilism.
Lesson 3 • Epistemic Injustice
Examines Miranda Fricker's concepts of testimonial and hermeneutical injustice. Applies social epistemology to issues of credibility, identity, and marginalization.
Lesson 4 • Testimony, Trust, and Expertise
Deepens the Chapter 2 treatment of testimony by examining trust networks and expert authority. Addresses how laypersons should respond to expert disagreement.

Lesson 5 • Epistemic Relativism and Pluralism
Evaluates claims that knowledge is relative to culture, framework, or perspective. Distinguishes defensible pluralism from self-defeating relativism.
