Introduction to Logical Symbols

[@sanaawan9579]

In Pakistan we really need teachers like you ❤

[@Informist101]

Are you a philosphy student?

[@macewindupage]

Really good. Thank you! Wish I could have seen this video back in 1986 when taking my first class in Formal Logic! Wondering how to make logical notation more accessible to my kids and this might help!

[@ALittleBitofPhilosophy]

All these videos are for beginners, so it might help. Thanks for watching and good luck!

[@xo.luvyana]

currently a college kid struggling in my Logic class! My professor is great, and you are really helping me out. Next, I’ll be watching you truth trees video (if you have one)

[@ALittleBitofPhilosophy]

Hi Eriana. I'm glad you found them helpful!

[@PinkyThapa-y5q]

Thank you so much sir this video really helps me...

[@sanaawan9579]

Very helpful thank you soo much 😊

[@jherbranson]

This is really well done. Thank you!

[@ALittleBitofPhilosophy]

You're most welcome. Thanks for watching!

You define order between parenteses, bracket and braces using numbers (first,second, thirt). But numbers are defined using logic. So it makes things circular. Is there not a way to define the order between the propositions without creating paradoxes

[@nopulpapple991]

Is there a puzzle book that anyone can recommend covering this material? I'm taking contemporary math, and I absolutely love this stuff. I'm just looking to keep covering the material in a fun way.

[@AAA-qr8yy]

There is a thinkfun game called robot repair that teaches logic gates. The same basic concept.

[@KKR-lv2cz]

Logic of relations, nature, characteristics and characteristics of relations plz made a vdo on given topic

[@ALittleBitofPhilosophy]

I'm working on other videos I've got to finish, but I'll put your suggestion in the queue for the future. Thanks for the suggestion!

@@ALittleBitofPhilosophy but i Need within 3 days bcoz 10 agust is my exam date

[@QuotesWorld987]

On 8:07 The statement: Kato is alive, but lusia is dead. The symbolic preposition should be: K. ~L Bcoz only then it explains the meaning of that complete statement. I think 🤔.

[@niaschim]

Statement, Proposition, Principles, Rules. Propositions emerge from statements. Rules emerge from principles. Moths emerge from coccoons. I'm leeeeeeeeeaaaaaaaaaaaaaaaaaaarning (I actually am)

[@himanshukeshtwal4658]

can you make video on proposition and its classification

[@λιμινιλ]

I wish I watch this video first.

[@vanneyaathithan9029]

Rey Bans are Expensive-- Why would that be a proposition?

[@ALittleBitofPhilosophy]

Technically, "Ray Bans are expensive." is a statement. The proposition would be the meaningful content OF the relation between the subject and predicate captured in the linguistic expression. But, for the purposes of introducing the concept of symbolizing simple and complex propositions in Propositional Logic (which is all I'm doing in these videos) we often oversimplify the distinction.

[@dipankar9574]

Now teach me how to construct truth table of complex statements

[@vanneyaathithan9029]

Is your "Definition of Proposition" correct?

[@ALittleBitofPhilosophy]

Hi Vanneya! Ok, so in Logic the word 'proposition' is a little fuzzy, and philosophers have struggled to give a clear sense of how we should use it. The problem is complicated by the metaphysical implications of thinking of "meaning" as something that exists independently of symbolic expressions (e.g., verbal expressions, linguistic expression, etc.). This is part of the debate between the Nominalism and Realism. For an excellent, and brief, history of the use of 'proposition' in Philosophy, I'd recommend the "Stanford Encyclopedia of Philosophy" article you can find here: plato.stanford.edu/entries/propositions/

whats the point of learning this

[@yudikubota293]

Your computer is doing this billions of times per second to allow you to write this comment

[@ItsSchwifty]

​@@yudikubota293 more like a million, a cpu would need much more cores to send that many instructions.

[@ALittleBitofPhilosophy]

Hi ItsSchwifty! It can seem a bit esoteric, and you and Yudi have hit on one practical application in terms of learning the foundations of computer programing. Of course, when it was invented/discovered, Propositional Logic was of interest as a way of creating a universal language that avoided the weaknesses of natural language. If we could create a language that was devoid of idioms and arbitrary syntax, it could be used by anyone without fear of misunderstanding. But, that's only part of the story. Thanks for watching and commenting!

[@mattheworchard481]

There's also this not symbol: ¬ Edit: I used and & and or / up until I watched this video.

[@ALittleBitofPhilosophy]

Hi Matthew! That is correct. There are different symbols used to designate logical operators. My videos follow the standard used in the Hurley editions of introductory Logic textbooks. Thanks for watching!

[@SumitKumar-vi2zj]

You are so lovely
