Rated 3 out of 5 by from This course is very well put together and the presentation is excellent. However, Dr. Kyle leaves us with his opinion as a conclusion to each section. If you agree with him, you will believe that there is no God, there is no soul, and there is no free will. We are just a product of an unexplained big bang, physics, and the resultant DNA. I would prefer that he present both sides and let us come to a conclusion. It would be great if Great Course / Wondrium had offerings from a religious perspective, if courses like this are offered from an atheist or agnostic perspective.

Rated 5 out of 5 by from Great start for a beginner Before writing this I must explain that I am person who got an engineering college degree in the 1950s at a college that was "all engineering, all the time". There was no liberal arts content period. After that I proceeded with an technical career in IT beginning in 1958. I am now retired (for the third time) and greatly interested the liberal arts that I missed. The professor was knowledgeable and animated in his presentation. The course is divided into sections based on topical points of view covering many of the most important schools of thought in philosophy. One might consider this as a History of thought as it covers the period from the ancient Greeks to well into the twentieth century. The first thing I had to do was to remember is based on opinion and as we all know "opinions vary". There is no absolute right or wrong in philosophy but it sure gives one pause to think about truth versus belief. Just to be able to ponder the thinking process in philosophy outside of the media of today is a Jewel. The course was well organized and I especially appreciate the course guide that gave about as much information as possible without becoming a transcript. The professor's coverage of the existence of God and the powers and responsibilities of government. I would recommend this course as a first immersion into philosophy for those seeking an introduction.

Rated 2 out of 5 by from The most soulless philosophy imaginable This is what happens when scientism tries to do philosophy. An amazing arrogance and hypocrisy that sings the praise of reason and end up abandoning reason almost immediately. My breaking point was the fifth lesson about theories of truth. He seems to miss that the problem the theories tries to solve is the question of the definition of truth. Instead he goes on and tries to evaluate them according to his own ill-defined definition of truth. That is a hell of a bias. A real philosopher would start questioning themselves and their biases about truth, and ask on what ground it is possible to do that. His whole thinking seems to be dominated by some democratic thinking that define truth as a majority decision. Probably because that is what he thinks the majority thinks. A sort of liberal conservatism that blocks any attempts to new and interesting ideas.

Rated 5 out of 5 by from The best philosophy course I’ve ever watched I love this course. Over the last month I referenced the lectures many times both at home as well as with with work colleagues. There are some real nuggets in this course that made me reevaluate many of my beliefs.

Rated 4 out of 5 by from A few factual errors Dr. Johnson errs in stating that neurons in the brain turn over like elsewhere in the body. Neurons normally stay with a person his whole life. More importantly his scientific evidence that we have no free will was founded on a theory of the meaning of the "readiness potential" in the brain that was effectively proven incorrect several years before he published his course. However this was one of the most interesting and expertly delivered courses of the 100+ that I have viewed. I would say that deep familiarity with Star Trek would be an asset, as his thought experiments are drawn heavily from that.

Rated 5 out of 5 by from Tough course, but stick with it I’ve found this course tough. It’s taken me a long time to work through it. But I’ve found it absolutely rewarding. The author has created a very comprehensive first course in Philosophy. I love the organization. It is by topic rather than by philosopher or chronology. The professor’s grasp and enthusiasm shines through. I recommend you purchase the transcript to follow along.

We have all pondered seemingly unanswerable but significant questions about our existence: Why are we here? What is knowledge? Does God exist? There is no better way to study the big questions in philosophy than to compare how the world's greatest minds have analyzed these questions and reasoned out potential solutions. The final step is always deciding for yourself whether you find an explanation convincing.


David K. Johnson

We can always take comfort in the fact that we can find and do embrace answers to metaphysical questions.
