Confusing
It seemed to me that the lectures consisted of long lists of oppositions to various claims and in some instances, those oppositions were adopted, in others rejected. The professor spent more time defending his own views rather than teach the basics of the philosophy of knowledge. He never defined clearly exactly what each of his claims were nor did he show the reasoning behind these claims, and why they were valid, or invalid in any straight forward reasoning. Most of his positions were "proven" in circuitous arguments and counterarguments. This course demonstrates how philosophy professors argue among one another more so than it teaches the student about the basics of the philosophy of knowledge; what it is; what constitutes justified knowledge; and what practices are needed to obtain it. The professor sounded defensive. The lectures felt as if the professor has a number of grievances he needed to let out. In spite of these criticisms, I was able to tease out the main points of his lectures and by following up with readings from other sources I learned for myself what the course should have taught but didn't.

Mediocre -- Ironic given the intended content
To rephrase the 1st line of the course summary "These lectures are intended as an introduction to the philosophical analysis of knowledge" based on actual course content "These lectures are an introduction to the philosophical analysis of knowledge by an examination of the professor's opinions on this subject." Given that presentations of differing viewpoints on various details of this topic always end with a presentation by the professor as to what he believes to be true I never had the impression that I was getting a good presentation of the various viewpoints; i.e. essentially it seemed very plausible that I was only being presented with enough of an outline for a viewpoint so as to allow for the professor to argue what his belief. I NEVER had the impression that I was being presented with the various approaches to the topic details such that I could then formulate my own opinions. And personally I mostly found the professor's presentation of their opinion to be unconvincing; this would be e true in something like Lecture 22: Pragmatic and Moral Encroachment.
Another angle from which I found the course to be mediocre and totally unfulfilling as a learning experience is that often I found the setup context for a lecture to be astonishingly weak. For example in Lecture 21: Testimony in the Media a significant amount of time in the lecture is devoted to 'fact checking' done by some media sources "... a practice that is only about 150 years old ..." -- so it then would appear that a discussion of the strengths and weaknesses, possibility or impossibility, of obtaining knowledge by the social context of testimony thru the 'media' is a something that could only happen since 1850 despite the fact that 'media' certainly predates 1850. My point being that a discussion of obtaining knowledge thru the social context of the media really is only tangentially related to a discussion of fact checking practices (as modernly defined). Building presentations on such weak foundations, poor contexts, gives zero confidence in the quality of the material.

Disappointing
It feels like professor Shieber is reading from an ill written book rather than teaching from his profound knowledge of the subject. Use of dense and tangled sentences makes it for a confusing student experience. Also overuse of concrete examples, especially from behavioral sciences, and drawing conclusive conclusions from them is perhaps not the best way to teach this course in epistemology.

01: Philosophy and Transformative Experiences
What do philosophical “theories of knowledge” have to do with everyday life? If you believe the field of epistemology is esoteric and abstract, you’ll be surprised by how fundamental it is to everyday life. In this opening lecture, reflect on how we make “transformative” experiences—and why common sense might lead us astray.
29 min
02: Knowledge, Truth, and Belief
Philosophers have been ruminating on the nature of knowledge for thousands of years. Using Plato as your guide, investigate the relationship between “knowledge,” “truth,” and “belief.” Professor Shieber brings in contemporary psychology and what we know about child development to show how we come to know what we know.
28 min
03: Foundationalism: Descartes’s Evil Demon
We’re all familiar with Descartes’s cogito, ergo sum, or “I think, therefore I am.” Delve into this powerful analysis of reality to discover what Descartes meant. As you’ll learn, he was trying to develop an infallible explanation for his knowledge of the world, which led him deep inside his own mind.
28 min
04: The Coherence Theory of Knowledge
Turn from Descartes’s theory of infallible knowledge to fallible yet still internal theories of reality. The most prominent theory is coherentism, a framework for understanding the world in terms of logical cohesion and consistency. While this theory has much to offer, you’ll also wrestle with several key challenges.
31 min
05: Externalist Theories of Knowledge
Not all theories of knowledge rely on internal justification. Here, you will explore several 20th-century approaches to knowledge that don’t require that justification is internally accessible. Consider how to gauge beliefs in terms of external consistency, accuracy, reliability, and validity.
29 min
06: Problems with Self-Knowledge
Given all this talk of beliefs and external reality, surely it’s safe to say we at least understand ourselves, right? Traditional, Cartesian epistemology may consider self-knowledge the foundation of all other knowledge, but as current research in psychology, biology, and neuroscience shows, our self-knowledge is far from complete or even accurate.
29 min
07: Does Sense Perception Support Knowledge?
One of the most significant sources of knowledge comes from sense perception—what we see, hear, smell, and experience of the world. Yet our common-sense way of thinking about sense perception is misleading at best. In this first of two lectures on perception, unpack the role of our senses in justifying beliefs about the world.
30 min
08: Perception: Foundationalism and Externalism
Continue your study of sense perception with a look at what it implies about the internalist and externalist theories you have studied so far. After examining several problems with internalist foundationalism, Professor Shieber explores how cognitive psychology supports an externalist view of knowledge.
28 min
09: The Importance of Memory for Knowledge
Memory plays a crucial role in knowledge because all of our perceptions are impermanent and fleeting. Here, you will examine the nature of memory. Are memories stored experiences in the mind, or are they past events themselves? And does memory merely preserve belief, or can you gain new knowledge from your memories?
28 min
10: Confabulations and False Memories
One of the most intriguing aspects of memory is just how fallible it is as a guide to reality. In this lecture, you will turn to how memory fits into the internalist and externalist theories of knowledge. False memories, confabulations, source theories, and forgotten evidence show just how tricky memory really is.
28 min
11: The Extended Mind
We are quickly approaching a future of augmented reality, simulated consciousness, brain implants, and more. These brain enhancements raise a number of philosophical questions: What counts as your mind? And is an enhanced brain a better brain? Consider the role of smart phones and photographs in preserving memory.
28 min
12: Do We Have Innate Knowledge?
Step back to one of the Enlightenment’s most captivating debates: Do we know the world through our own minds (as Descartes argued) or through empirical evidence (as Locke and Hume argued)? After unpacking this debate, see how Kant came to the rescue to distinguish between a priori and a posteriori knowledge.
29 min
13: How Deduction Contributes to Knowledge
Much of our belief system stems from things we have not experienced directly; rather, we infer much of our knowledge through the processes of logical reasoning. Here, tackle the role of deduction, in which inference stems from the logical relationship of a series of steps. Consider syllogisms, “if-then” arguments, and other deductive procedures.
29 min
14: Hume’s Attack on Induction
Deduction and induction are the two types of logical inference. In this first of two explorations of induction, you will examine the reliability and usefulness of induction. You’ll start with David Hume’s challenge to induction to see whether it can be used to generate knowledge at all. And even if knowledge comes from inductive inference, are humans any good at it?
28 min
15: The Raven Paradox and New Riddle of Induction
Continue your tour of induction by looking at a few logical puzzles. There are no easy answers to the raven paradox or the new riddle of induction, but picking apart these challenges can offer valuable lessons about inductive inference. Revisit Hume’s attack, and reflect on how Bayes’s theorem of probability applies to inductive reasoning.
28 min
16: Know-How versus Propositional Knowledge
So far, this course has tackled “propositional knowledge”—or knowledge that X is true. But knowledge-that isn’t the only kind of knowledge. Although philosophers didn’t think much about knowledge-how (know-how) until recently, it has much to teach us—especially about internalist and externalist theories of knowledge.
30 min
17: Knowledge Derived from Testimony
Sensory perception, memory, self-awareness, and logical inference are all personal sources of knowledge, but much of our knowledge comes from consulting others’ expertise. Discover the breadth of knowledge that comes from testimony, and find out what perils exist in relying on the word of others.
28 min
18: Social Psychology and Source Monitoring
To evaluate knowledge that comes from testimony, you might think we analyze the trustworthiness of the source and weigh our beliefs accordingly. But as social psychology tells us and you will see here, we are very bad at spotting liars, and we tend to accept testimony without consciously monitoring the source of the information.
29 min
19: Testimony through Social Networks
Social networks play a powerful role in how we acquire knowledge from others. Here, explore the nature of our social networks—how many close friends we tend to have, and how many people are in our wider social network—and then see how our networks provide us information, and how reliable the information is.
28 min
20: The Reliability of Scientific Testimony
Previously, you discovered the “social externalist” theory of testimony. Examples from the scientific world provide evidence for this view of ensuring accurate testimony. Reflect on several scientific achievements made possible by “socially distributed cognitive processes”—processes where the sum is greater than the individual players.
29 min
21: Testimony in the Media
The media is a great example of a socially distributed process—but how do we know the information is reliable and accurate? Go inside the world of media fact-checking and how our media consumption impacts our knowledge. Consider the challenge of ensuring accuracy in the age of “click-bait.”
28 min
22: Pragmatic and Moral Encroachment
Much of this course has focused on the truth-likelihood of knowledge, without focusing on the particular interests of the knower. In this lecture, survey two key challenges to this approach: First, do your practical interests impact whether you have knowledge? Second, do your moral concerns impact whether you have knowledge?
27 min
23: Radical Skepticism: The Brain in a Vat
Return to the beginning, in which you studied Descartes’s radical skepticism. While there are many problems with Descartes’s theory of knowledge, his fundamental skepticism is tough to reckon with. How do we know we are not just a brain in a vat, à la The Matrix? Delve into several arguments against this scenario.
28 min
24: The Future of Epistemology
Epistemology is an old field, but in the 21st century there has been an explosion of new ideas, approaches, and applications. Conclude the course with a look at the future of the field, including “formal epistemology,” “epistemic injustice,” and the potential integration of externalist, foundationalist, and coherentist approaches to knowledge.
