CRITICAL THINKING - Fundamentals: Deductive Arguments

In this Wireless Philosophy video, Geoff Pynn (Northern Illinois) follows up on his introduction to critical thinking by exploring how deductive arguments give us reason to believe their conclusions. Good deductive arguments guarantee their conclusions, and so must be valid (i.e., it must be impossible for the premises to be true while the conclusion is false) and have true premises. Philosophers call arguments like these "sound". You can see whether an argument is sound by trying to think of a counterexample to it, but to see whether its premises are true, you need to do some research.

This was a whole week of lectures in just over 5 minutes. Wow.

Schools need to teach this subject starting in grade schools... Students are taught "what" to learn/ think but not "how" to.

Thirty years ago in college I got a grade C in Introduction to Philosophy 101 class. I just didn't connect with the subject. It is amazing how people share knowledge for free on YT. Your videos are most excellent. Thank you!

I've become obsessed with developing my critical thinking skills ever since trump was elected president. I'm determined to help a couple of my republican friends see the error in their reasoning. Both are well educated and quite bright so I have a lot of work to do! Thank you for these wonderfully concise and clear videos!

I have been having a horrible time in my PHI class. I have no clue why I am not picking up on this material. I have a 4.0 for goodness sakes! My professor has been working his bootie off to assist me. I guess I am one of the doomed who is destined to never have any common sense. This video gets an A+ from me, but I do not think I have gotten it any better as of yet.

It's such a well-animated video on an important topic that everyone should be familiar with... so why so few views?  :(

Geoff has had a shave since the last video... I deduced this from the 2 photos.

Thanks for these videos. The world needs this!

Started watching this series in 2024, 9 years after uploading date. I'm 21 now, thinking why school didn't develop my interest in this subject. My interest got developed in this subject, when I started doing Debates as co-curricular activities.

4:16 I think this is beautiful because it demonstrates that the rules of logic and deduction were established using induction

[salome]

The fact that you write everything down makes it easy to write notes😊

Really nice video, but the subtitles are a few seconds of sync.

Induction is when we get the conclusion which is most probable from the premises. We cannot be certain of this. Deduction is when we are certain from the premises. In the fictitious character Sherlock Holmes, he is actually practicing Induction instead of Deduction. I think Sir Arthur Conan Doyle did this to add to Sherlock's ego.

@4:34 Did he mean "even if you know the argument is VALID"? He said "sound".

[jedboy]

If I attack an argument because it commits an informal logical fallacy (begging the question, ad hominem, etc.), am I attacking its logical validity or its soundness?

[ZackGomez]

I am studying this for my critical reading class today. It has enough views when it's over 1, 000 in my opinion.

[raasshaaadd]

Do you offer or know of any interactive online resources that will help with retention and mastery of this topic. For the ones not in college or pursuing secondary education?

[okc]

If a deductive argument has false premise does that mean that the conclusion is also false?

[TheQuebecMan]

Im so happy this pass trough my feed !

[yeghor]

It's like a logical type equation.
