A quick video because I need to explain the reason for the recent hiatus on videos - it might resonate with some of you. Check out these channels for more logic (and other educational) content. www.youtube.com/@UCGYSfZbPp3BiAFs531PBY7g www.youtube.com/@AtticPhilosophy
LOGIC (Part 5 - Theorems and Substitutions)

Hello and er... thanks for waiting ... again... if you have been. I hope that this video is worth it, I will be making another Vlog over the next few days to explain.
LOGIG (Part 4 Bonus - Different Notations)
มุมมอง 1072 ปีที่แล้ว
Here is a bonus video to part 4 of our series where we look at different forms of notation for logic. This is not all possible forms of notation, and it is possible that I have made some errors in my explanation. If you are interested in any of these notations you should look into it for yourself. 00:00 - Introduction 01:25 - Quantifiers (coming soon) 02:22 - Set 1 (Our format) 03:28 - Set 2 (A...
LOGIC (Part 4 - Syntactic Logic)

Hi, thanks for waiting, here is part 4 of our logic series where we actually leave language behind altogether and look ad a basic way of analysing arguments from their syntax. If you have any comments or questions please leave them below.
LOGIC (Part 3 Bonus: The Laws of thought)
มุมมอง 3.4K2 ปีที่แล้ว
Here is a bonus video on the fundamental laws of thought that come even before the logic we have learned so far; they give us a bit of a look at what logic can do for us in the world. Please let me know what you think below. ^^
Logic (Part 3 - Arguments & Validity)

LOGIC (Part 2 Bonus: Necessity and Sufficiency examples)
มุมมอง 3782 ปีที่แล้ว
To build on what we saw in the main video. Here is a set of examples about necessary and sufficient conditions. These examples are borrowed from Norman Swartz at Simon Fraser University www.sfu.ca/~swartz/conditions2.htm and are used under fair use for transformative work.
LOGIC (Part 2 - Truth Values and Expressions)

In part 2 of this series, we look at how truth tables work to show us truth values, and touch on a few things that will help us think more clearly. 00:00 - Intro 01:04 - Truth Tables - Intro 01:58 - Truth Tables - More than 2 lines 03:50 - Truth Tables - Conjunctions and disjunctions 05:52 - Truth Tables - Conditionals and biconditionals 08:32 - Key Concepts - Expressions 09:35 - A word on JARG...
LOGIC (Part 1 BONUS: What is abstraction?)
มุมมอง 9882 ปีที่แล้ว
An additional video for part one of our logic series where I try to deal with one of the common problems people have with logic - it is so very very (very) ABSTRACT! What is abstraction, how does it help us? And why is it so connected with logic. This video gives my explanation, please let me know what you think 00:00 - Intro 01:03 - An example of abstraction 01:57 - Level 0 - Reality 02:18 - L...
LOGIC (Part 1 - Statements & Symbols)
มุมมอง 1.6K2 ปีที่แล้ว
Logic is too abstract to start when you begin maths, but it is the most basic ideas that make maths work. Here we start to look through the beginning of this very important subject. This is an updated version of a previous video on this channel. 1. Introduction - 00:00 2. Statements and Truth Values - 01:05 3. Axioms and Compound Statements - 03:12 4.

These are just a few of the basic things that you will learn about sets. We have a couple more older videos on sets here: th-cam.com/play/PLvWXNCzIK0KAIJQvCppLnhZVQD7EevzDO.html Can YOU spot the terrible ADR moment?!! o_O Thanks for watching

Really your referencing Wikipedia
thanks
This is much better than many of others. IDK why theres no likes at all…
Your amazing 🔥
Very good class
Thank you sir 🙏
"Maybe it would be a better world if they did" Best statement I've ever heard
Thank you very much for your course of logic. Contrary to may other courses, where the respective teacher speaks a doubtful English, not so easy to understand, your method of giving lessons is most welcome for a non-native English speaker. I am really thrilled and lucky to have found your presentation on this channel.
Hi Adam. Thanks for this course, I'm really enjoying it. Just to let you know there is an error in the slide at just before 4 mins, when you're introducing the bus / train to London example. Your spoken word has it correct, but the second sentence of the slide has the bus and the train the wrong way round. Best wishes, John
Statement: "This is a statement." 😆
Bro tomorrow is actually Tuesday no way
Excellent! Thank you for sharing!
Appreciate that, hope it helps. :)
Sir kindly reply me what is the base of set theory I know concept and history but quiet confused for at what base the Sir George Cantor invented set theory
Thank you.
Thanks you so much It clear and understandable

Will any more video come ?
Hi Sorry about the hiatus :( Life y'know. Logic 5 is recorded. Watch this space. Thanks for checking in. :)
Hi there, awesome video. To be clear, the letters used in this video are used as stand-ins for simple statements, yes? Thank you, Are there any other great resources for learning logic?
Good stuff
I love the "you are not alone" FFIX theme playing in the background, I certainly didn't expected it. Great video btw!
Just discovered this channel; trying to learn some logic principles before I take a programming boot camp. So far, I like this playlist but the background music distracts me lol.
Thanks, I am actually remaking this series on logic and there is no music in those newer videos. :)
Well , as a foreign student , i have studied this lesson in french and i wanted to see the English version . It is super cool
❤️ 𝓅𝓇𝑜𝓂𝑜𝓈𝓂
Thanks for share it!
Does anyone have a video or article that talks about the symbols ∈, ∀ and ∃ ?
Hey!! Im studying for an exam and your videos have been reeaaally useful, do you know if there's any lists of exercices online regarding the subject in theses videos? I can't find it
😁😁😁😁😁
a statement may be stupid or ridiculous, though logical
Cautiously agree ^_^ - that will always depend on the context.
hyyyyyyy great bro
Great, keep it up 👍
Thanks, hopefully I can keep them coming. :)
Is this deductive or inductive logic or both?
Hi, it is mostly deduction (or natural deduction). You can use many of the same techniques for induction, but your premises are less certain. This series is being updated if you check our latest uploads. :)
could you tell me the reference please ?
I will cross reference from many different sites on the internet but from part 4 I will use LOGIC by W.H.Newton Smith as a text to help me with these videos.
When I use the word "inverse", I mean that the pair of questions use inverse condition types (necessary or sufficient); but these examples also invert A and B in different places - and inverse can have other meanings in maths, so this was a bad word choice all round 😬😆

Ty for the video sir☺
Thanks for the support. I am trying to keep the writing going (work is busy right now too :/ ) but it is good to know there are people finding it helpful.
@@adamprance9456 sure, ty sir for make it. I gonna wait for the next video☺
Thanks for sharing this.
Thanks for watching, hope it helped. :)
Trying to make sense of why this doesn't have more views. It's amazing
im only here because our exam is in the next week and our teacher decides to just give a bunch of texts and expects us to understand it :)
I hope it helped. :)
This was exactly what i needed to expand my abstruction level interms of thinking...
Glad to hear it. I am updating this series, including this video on abstraction. Hope you enjoy. :) th-cam.com/video/kGorDWQDJRA/w-d-xo.html
@@adamprance9456 thank you bro...
OH MY GOD THANK you. you just saved my life. thank you thank you thank you thank you
Awesome! So happy it helped. :)
You are a good story-teller (teacher). Please, develop your channel. It could grow in a beautiful source of information.
Thanks so much for the support. I will try to keep it up. Life gets busy but it's good to know that people are enjoying these videos.
truth or falsehood
15:59...in this day and age LOL. This is why the world is ___'ed up!!!
this is actually so great! looking forward for next episodes
excited for part 2!!
there goes my A in math

Nice 😆😆😆, gonna wait for the next video, sir. I like your explanation😁.
