What Will I Learn?
  • By the end of this course, you will be able to efficiently spot fallacies in the arguments of others and avoid making them yourself.
  • You will learn all about the (in)famous fallacies, such as: the "strawman argument", the "gambler's fallacy", the "red herring", the "slippery slope" and "appeals to authority and/or popular opinion".
  • You will be presented with example situations and talks, involving even some of the more sophisticated and complex fallacies, such as: the "fallacy fallacy", "tu quoque fallacy", "Shifting the burden of proof" and the "No true Scotsman fallacy".
View Curriculum
  • The course is self-contained and intended for a wide range of age groups (though I will give out some book recommendations for the especially eager).

A fallacy is a poorly reasoned argument and those are all around us and even unintentionally come out of our own mouths sometimes!

Avoiding fallacies is a crucial skill, especially in the age of information we live in! The internet is full of debates. Full of arguments. And full of fallacies and tricks!

After this short course you will no longer have to look up what people are talking about - after this course you will be explaining and pointing out what has been wrongly argued and why.

In just 3 days, you will have a strong setting in the art of spotting and avoiding poor arguments. This will in turn make your arguments stronger!

  • On Day 1 we will have a look at the most common and easy to understand fallacies.
  • On Day 2 we will approach some of the more complex fallacies.
  • On Day 3 we will be talk about some more implications of your new-found knowledge and where you can take things from here.

You can naturally also pace the course however it fits your schedule: You get lifetime access to everything in this course! Of course, you will be provided both real life and abstract examples of the fallacies at hand, while fun quizzes will test and review the stuff you have learned so far!

Complete transcripts and downloadable slides of all course lectures available in the supplemental materials of each video.

I am always available to answer questions and contribute to discussions about the course material and beyond!

And as a special bonus, further readings and media recommendations (books, movies, etc.) will be made for aspiring philosophers. Come join our group of students today!

Who is the target audience?
  • People who often find themselves in discussions.
  • People who prefer not to be tricked by language or the mind.
  • People who enjoy philosophy, especially analyzing arguments.

This list is the promised further readings recommendations. I consider all the books on this list excellent and hope you will choose to stay with Informal Logic and Philosophy. There is much more for you to explore in this wide-ranging subject.

If you wish to get recommendations for more specific branches of philosophy, feel do not hesitate to contact me and I will be happy to share more of my personal recommendations with you.

This list will tell you about a few movies, one tv series and a series of video games which I consider an entertaining way to have more contact with what we have learned in this course. I consider all the recommended media excellent but I am aware that it is subjective. I hope some of you will find some enjoying moments in those while re-discovering some of what we talked about.

If you have recommendations of your own, let me know, so I can add them to my list.

Also be sure to check out the recommended readings in lecture 18.

Philosophy and Physics Student at the University of Vienna

I am a student of Philosophy and Physics, my focus of studying is in Philosophy of Science, Epistemology and Formal Logic and Theoretical Physics respectively.

As an aspiring scientist and philosopher, the art of keeping one's thoughts straight to the point and logically valid is essential and crucial and I have been studying it for many years, having completed a number of courses in both formal and informal logic.

I've spent a volunteer year taking care of children and teenagers after school, where it was among my responsibilities to help them with their studies and explain what had not been properly explained to them. During this experience, I have found a joy in sharing what I have learned with others and with the power of the internet at our fingertips, I can think of nothing more fulfilling than sharing my passion for philosophy and reasoning with other interested people all across the world.

Humans thrive by communicating - let my knowledge and experience in the subject guide you around common traps.
