I love The Great Courses Series. It's like attending an Interesting lecture. The emphasis is on interesting if you haven't guessed.
But the one I want to plug right now is
The Lecture is given by Dr. Steve Novella.
If you're an avid fan of the podcast The Skeptics Guide to the Universe, you can probably skip on ahead. If you aren't , well lets cut and paste some of Steve Novella's resume:
Dr. Novella is an academic neurologist at Yale University School of Medicine. In addition to being the host of The Skeptics' Guide podcast, he is the president and co-founder of the New England Skeptical Society. He is also the author of NeuroLogicaBlog, a popular science blog that covers news and issues in neuroscience, but also general science, scientific skepticism, philosophy of science, critical thinking, and the intersection of science with the media and society. Dr. Novella also contributes every Sunday to The Rogues Gallery, the official blog of the SGU, every Monday to SkepticBlog, and every Wednesday to Science-Based Medicine, a blog dedicated to issues of science and medicine. He is also a fellow of the Committee for Skeptical Inquiry (CSI) and a founding fellow of the Institute for Science in Medicine. He has a regular column in the Skeptical Inquirer - The Science of Medicine. Dr. Novella is also a Senior Fellow for the James Randi Educational Foundation and directs their Science-Based Medicine program. Dr. Novella is available for public lectures, radio, podcast, or other media appearances. Contact him through the contact page or at firstname.lastname@example.org to request an appearance.
All that and a real job. Whew. Remind me to stop kvetching about two jobs.
The course is great if you are new to this whole critical thinking thing. Or for that matter, even if your not.
I highly recommend it.
