What comes to mind when you hear the word “metaphysics”? The truth is, while metaphysics is among the oldest strands of philosophical thought—an inquiry into the very nature of reality—metaphysics is also on the cutting edge of today’s scientific discoveries. Now you can take a journey through the limits of today’s knowledge in Exploring Metaphysics. Professor David Kyle Johnson identifies our fundamental assumptions about the world—and then proceeds to challenge those assumptions point by point. You’ll be surprised to learn what relativity, quantum mechanics, and neuroscience imply about human free will and that time travel is not as crazy as it sounds.
Exploring Metaphysics
Explore the cutting edge of scientific and philosophical understanding with this fascinating course that delves into philosophy, theology, neuroscience, artificial intelligence, relativity, quantum mechanics, and more.

Excellent Course and Teacher
Despite the majority of 4 and 5 star reviews, before procuring any lectures from The Great Courses, I always read the 'one star' reviews to gain perspective from those who regretted their purchase. Perhaps I'm mistaken but I suspect the bulk of one star reviews written by theists, unwilling to consider any philosophy perceived to threaten their religious dogma.
I bought the course anyway and glad I did.
The study of reality is of great interest to me and I rate this course and professor Excellent.
If you prefer to avoid a challenge to your religious beliefs, run from this course but if you are on a genuine search for metaphysical truth, this is a great place to start I highly recommend Exploring Metaphysics.

Very interesting
I do have an issue with his reasoning. Using his reasoning I should draw an irrational conclusion from the below thought exercise:
A car is driving down the street, a child runs in front of the car the car does not break, therefore there must be no driver
This is obviously false reasoning as there could be many reasons. The breaks are broken extra

Exploring Metahistory
Once upon a time there lived simple folks who wondered about grass coming up every spring, cows being born and dying and why they had dreams at night. So, the wisest men among the simple folks band together and started looking at things diligently and talking about things in orderly fashion. And the simple folks rejoiced because now they could understand and they gave the wise men food, clothing and respect and called them philosophers. Behold, there were some wicked men among the wise men who were not wise only smart. And they invented new words and put words together in unexpected ways so as to confuse the simple folks. And the wicked men had begotten this course. And the simple folks were perplexed and blamed themselves for not understanding.

Highly Engaging
I have several of Dr. Johnson's courses and enjoy them all. He is an excellent instructors who makes somewhat difficult material easily accessible. The illustrations and examples that he provides increase interest and clarity and find myself wanting to learn more from him when each concludes. These lectures are a wonderful asset to my collection and I highly recommend his professor.

Terrific scope
I would give this more than a 5 star rating if that were possible. It covers many, many aspects of the subject, all of them rather thoroughly. I particularly liked his work on quantum mechanics, which doesn't usually get into metaphysics courses. I also was intrigued by his rampant enthusiasm for sweet potato french fries, which I had never heard ot. I'll have to find some!

The title matches product conduct
The course is an excellent survey of metaphysics. The presenter's pace, tone and occasional digressions added to my enjoyment of the course. If you take the time to read each chapter summary before listening and read a few of his additional reading suggestions your learning experience will be enhanced.

01: How to Explore Metaphysics
Delve into the world of metaphysics, the study of the fundamental nature of reality. This opening lecture introduces you to the realm of unanswered questions and the limits of scientific understanding. While there will be few definitive answers, the goal will be to understand some of the most important questions we can ask as human beings.
32 min
02: The Mystery of the Mind and the Soul
How does the brain produce the mind? This question, which philosophers call the “hard problem of consciousness,” is at the heart of the philosophy of mind. Begin this unit with a look at how brain activity translates into mental activity—consciousness—and what role, if any, the soul plays in all of this.
29 min
03: Identity Theory—Token and Type
Survey several ways philosophers have attempted to explain the mind through material means. Two kinds of identity theory offer solutions to the problem of consciousness, yet each has difficulty accounting for the seeming distinction between mental activities and the brains that produce them.
25 min
04: Functionalism and Artificial Intelligence
This lecture continues to explore identity theory and takes you to the intersection of science and metaphysics. If our brains are functional—in other words, they operate like a computer program—could computers one day possess consciousness? And if we one day construct “minded” androids, what should our relationship with them be?
29 min
05: Alternative Theories of Mind
Wrap up your study of the mind with three final theories. Consider whether minds exist at all, reexamine the relationship between physical and mental properties, and explore whether the mind has any causal power at all.
26 min
06: The Problem of Personal Identity
Start the next unit by defining the problem of personal identity over time. Imagine yourself at eight years old and how much you’ve changed since then. Are you still one and the same person? What makes that identity consistent? Revisit the idea of the soul as housing for a person’s “essence.”
27 min
07: Mind, Memory, and Psychological Continuity
If the soul hypothesis for personal identity isn’t satisfying, turn to memories and psychological continuity. Would your “self” be preserved if your memories and psychology were transported from one body to another? In this lecture, you’ll be surprised by just how many of our intuitions about personal identity seem to conflict.
28 min
08: Same Body, Same Brain, and Closest Continuer
Examine some of the physical requirements for maintaining personal identity. Comas, cryogenic freezing, organ transplants, and Star Trek transporters are just some of the many ways our physical identities could be disrupted. Then see how combining the psychological and physical characteristics led Robert Nozick to construct the “closest continuer” view of identity.
30 min
09: The No-Self Theory and Time Worms
Ponder two final theories of the self—the possibility that the “self” doesn’t actually exist as a discrete object, and the notion that the “self” exists in four dimensions. Then turn to a host of problems that arise from considering the self across time.
29 min
10: The Nature of Truth and Time
In the last lecture, you saw that the “self” might exist in four dimensions across time, which raises questions about the very nature of time. Here, you’ll explore the problem of human freedom and divine foreknowledge. Then you’ll learn about logical propositions and truthmakers, and see what logic implies about free will and the future.
27 min
11: Libertarian Free Will
Take a closer look at human freedom, beginning with “libertarian free will,” which requires the possibility of not choosing as one will. Then discover several challenges to human free will: physical determinism, the random indeterminate nature of the quantum world, and the way our brains make decisions.
28 min
12: Compatibilistic Freedom
Is it possible that, even if we lack libertarian free will, we are still free in another way? Interrogate the theory of compatibilism, which says that as long as your actions flow out of your wants and desires, then you are acting freely. After exploring the source of our desires, turn to the moral and legal ramifications of a world without free will.
28 min
13: Causation, Possible Worlds, and Propositions
Before shifting from the nature of the self to the nature of reality, take a step back to reflect on causation. What does it mean to say one thing “causes” another? Your exploration takes you into the world of modal statements, truthmakers, possible worlds, propositions, and universals.
29 min
14: God—Definition and Paradox
Professor Johnson begins his inquiry into the nature of God with definitions: God as an omnipotent, omniscient, and omnibenevolent being. Consider how this definition may generate paradoxes, including conflicts between perfect power and goodness, perfect knowledge and free will, and the impossibility of being perfectly just and perfectly merciful.
29 min
15: God—The Argument from Existence
The first of three primary arguments in favor of God’s existence is a purely conceptual, deductive argument. The medieval Benedictine monk Anselm argued that, logically, God must exist in order to fulfill our conception of a perfect being. This argument and its objections have raised numerous questions about the nature of existence and the limits of reason.
27 min
16: God—The Argument from Cause
The second argument views God as the original uncaused cause at the beginning of the universe. Here you’ll see that this argument, too, has its flaws that range from the indeterminate—uncaused—nature of the quantum world to the much simpler argument that the universe is simply unexplained.
27 min
17: God—The Argument from Design
The final argument for God’s existence views God as a cosmic watchmaker who set the world into motion in such a way that life could emerge. Professor Johnson lays out this theory and explores some of its many challenges, including the idea that the universe is not all that fine-tuned and that there may be more than one way to build a universe.
28 min
18: From Spinning Buckets to Special Relativity
Transition from the nature of God to the nature of reality. After investigating whether space and time are actual substances or merely relational, Professor Johnson delves into special relativity and explains the counterintuitive implications that the constant speed of light has for speed, motion, length, and time.
29 min
19: From General Relativity to Space-Time
Professor Johnson continues his analysis of relativity, this time taking gravity and acceleration into account. See what astrophysicists mean by the curvature of space-time and what it implies about gravity and the very fabric of the universe. Finally, reflect on what space-time implies for human free will.
29 min
20: Black Holes, Wormholes, and Time Travel
Revisit the intersection between science and metaphysics. General relativity suggests the universe is a giant block of space-time, so does that mean time travel is possible? Examine the feasibility of traveling to the past or the future, and consider the paradoxes that might result.
29 min
21: Quantum Mechanics and Wave—Particle Duality
Enter the wild world of quantum mechanics. After an overview about probability, your study of atomic theory begins with the randomness of radioactive decay, which is undetermined and uncaused. Then shift your attention to the dual nature of light as both a wave and a series of particles.
30 min
22: Quantum Mechanics, Spin, and Spooky Action
Continue your study of the quantum world with a look at Heisenberg’s uncertainty principle, which implies a particle’s properties—such as location, momentum, and spin—are indeterminate until someone measures them. This phenomenon has several strange, inexplicable implications—like Schrödinger’s cat.
31 min
23: Quantum Mechanics, God, and the Multiverse
Find out how scientists have attempted to answer the questions raised by quantum mechanics. One possibility is that there are multiple universes that exist simultaneously in a fifth dimension. You’ll discover that this theory goes a long way toward explaining reality without violating the laws of physics.
30 min
24: Do We Live in a Computer Simulation?
There are still many unknowns about the nature of reality. In this last lecture, you’ll be startled to find out just how likely it is that we live in some sort of computer-simulated world. Professor Johnson walks you through the argument and its implications before summing up what you’ve learned—and what questions still exist.
