- Join George and John as they discuss and debate different Philosophical ideas. Today the two will be discussing Logical Reasoning. This is the method Philosophers use to create sound and valid arguments. The two will run through different arguments to show what makes a logically valid argument, a logically sound argument, as well as a logically invalid and not sound argument. They will also look into different kinds of Logical Reasoning such as Deductive reasoning, Inductive reasoning and Abductive reasoning. By the end of this video you will have a greater understanding of formulating a good argument, making the way you debate valid and sound, perfect practice for any debates you will find yourself in.

Yes I understand
XD
Well I don’t :
Yes me too I finally understood after watching three videos explaining this
This gave me an "ah ha" moment even after reviewing all of the material provided by my instructor. Thanks for clearly defining the difference between valid and sound arguments.
Me too. Within the first 2 minutes. I'm glad I found this video.
Learned more in this video then I did these past weeks in class.
Glad we could help :)
that guy in the purple shirt is a mood
Amazing video! Concepts well explained!
Super clear and concise, I understand the terminology now. Thanks!
Pleasure, thank you for watching.
Great video!!! Keep them coming!
Thank you, don't worry, still a lot more to come!
Thank you people for your good and clear work it help me alot........
Glad we could help :)
You guys are bloody legends
Thank you :)
Loved it!
Thank you :)
This videos help me a lot from the time I start watching them my grades in philosophy have improved a lot 👊🏼👊🏼👊🏼
So glad to hear this, we're delighted we could help. Best of luck in your philosophy course!
I have to ask you: the men are mortal example - isn’t the first statement “all men are mortal” an inductive reasoning derived statement?
So how can we say that the example is both sound and valid. I understand it’s valid as conclusion logically follows the premise, but to be sound it must be valid and premises and conclusions must be all true: but since we cannot assume the first premise is true, we lose the potential for soundness.
Am I correct?
I must say I also take issue with the idea that abductive is less probably than inductive and that abductive uses inference (but inductivr doesn’t). Inductive uses inference by inferring the conclusion based on assuming that what happens in the past is a predictor of what happens in the future.
thank you so much for this
You're very welcome!
i was having a panic attack before encountering this video, thx!
Glad we could help.
this is amazing! like watching cartoon and doesn't feel like doing assignment at all.
Thank you, glad you enjoyed. Good luck in the assignment.
Awesome :DD
Thank you :)
Thanks ❤❤
You're welcome.
identify the following as valid constant or variable and write their type if not valid then state the kind question name one
Gracias
You're welcome.
How do I make these videos
You guys have any book recommendations ?
Are you looking for fiction or non fiction?
Philosophy Vibe nonfiction but anything that will enhance my knowledge in philosophy is fine.
One of the best books for a wide overview on all major areas of Western Philosophy is - John Cottingham's, Western Philosophy an Anthology. Many different theories from all major Philosophers are included, snippets from their original works as well as a clear concise summary from Cottingham. This book will really enhance your knowledge on many different areas of Philosophy.
this is aristotle's logic.
can you do mathematical logic?
bruh mathematical logic is built on aristotle's logic
@@bzzzzzzzzzzzzzzzzzz its the other way around i think
Awesome. The Video still has the black border.
Thank you. And yes, after a day or so RUclips gives me the option to remove the black box but it doesn't happen automatically when I upload them. If you go back to the Miracles video the black box should now be gone.
The concept of invalid is ableist
All humans are mortal, isn't that premise based on induction?
I’m actually wondering the same thing!!
The thumbnail is misleading.
p..plato is that you?
I disagree with deductive reasoning. “1. All men are mortal. 2. I am a man. 3. Therefore, I am mortal.” How did you know that all men are mortal, to begin with, if you did not already first establish that you are a man and are mortal?
“1. All humans have brains. 2. I am a human. 3. Therefore, I have a brain.” How did you know, to begin with, that all humans have brains, if you did not already first establish that you are a human and have a brain?
For an argument to be sound, it requires only that the argument being valid and the premises being all true.
For an argument to be valid, it doesn't matter if the premises are true, it requires only that the conclusion logically follows from the premises. And in the two arguments you mentioned, the conclusions do follow from the premises logically, hence they are both valid.
Since the two arguments are both valid, the question that whether they are also sound depends only on the fact whether the premises are also true.
But note that whether a premise states a truth is an objective fact. A premise can state a truth even if no one knows whether it does. Hence, even if the creators of this videos do not know whether the premises of the two arguments you mentioned are true, the premises can still be true, therefore the arguments can still be sound.
Indeed, if the creators in fact do not know whether the premises are true, they cannot know whether the arguments are sound. Therefore they do not know what they say i correct or not. But that doesn't prevent what they say from actually being true.
So what you are saying is technically speaking the authors made an error!!!!
ete sech
Can you do this for white privilege?
I’ve struggled to come up with a sound and valid argument for it.
like the videro but you could get a better animator and make the conversation more realistic sounding
U should also have noted that deductive reasoning may lead to a valid but unsound conclusion if the premises are false.
So nothing that science tells us is certain
Biology tells us that if you are human you have a brain. The more recent a discovery is the less certainty there is. Things need to be repeatable.
@@justinbarnard8749 There is always the problem of induction inherent in the scientific method that leads to uncertainty regardless of repeatability.
@@baburali8230 it doesn't necessarily LEAD to uncertainty, in fact, if your finding was not repeatable it would certainly be false. The concept of certainty isn't a zero-sum game and in many ways can be subjective in and of itself because there are degrees of certainty. A person can have certain beliefs that are incorrigible but certainty doesn't make them indubitable. The reason I can be certain that a living human will have a brain is because it is a taxonomic definition. Sure, there could be a zombie apocalypse eventually but in that case we'd have to view it as humans can BECOME zombies. Until that first zombie baby is born and they become an evolution of man.
Vague claims
I like these videos
Yes I understand
