Modus Ponens

This video introduces the valid argument form known as "modus ponens".

[Cking]

Thank you! 1 min in, and I have come to the conclusion that your a better teacher then the one I have at college.

[Ukrainian-woman-of-your-dreams]

I can learn well about "modus ponens" from this video as I do from my course textbook which is called "Thinking Critically, 12th Edition".

[Helvio]

[bhavinjawade]

Your voice is just like the person who used to teach me meditation in school.

If you are a sandcastle, then you are a time traveling genius.
You are a sandcastle
Therefore, you are a time traveling genius.

Whooo! I did it!

[alishafitzgerald]

How would this work out if given:

If A then B
If B then C
Therefore,
A then C...

There is nothing online to demonstrate this to me. I'm scared to death of this class. It seems like everyone else is being assigned easier truth tables than me.

[jovannatsalikoglou]

How can i do modus tollens with the unless?

[brandomiranda]

what is the course that this video is referring to? Is it a set of videos or something?

[Karan-yntd]

[Woshii]

If p then not q
not p
therefore q?

[plushiie_]

wait other universities don't teach this as a common subject?

They could probably be ignored... But why should "something be done to them"? Just leave them alone and stop dealing with them. They'll figure it out sooner or later. If you recognize that you may be an unwitting and/or willful participant in fraud yourself, then seek to correct yourself and don't worry about what "should be done" to anybody else. Just mind your agreements and don't contract with crooks because the addiction to ill behavior is not worth the dependency.

This presentation is like Apple's keynotes :D

Your comment doesn't make a whole lot of sense so it is hard for me to comment on it. You claim "lawful" and "legal" are not the same thing. You are wrong. Goto dictionarydotcom and look up "lawful" and "legal", the 1st definition for both words are essentially the same. For "legal" the first defintion is "permitted by law; lawful". For "lawful" the first definition is "allowed or permitted by law; not contrary to law". How is one definition substantially different from the other?

[AbsalomMelchizedek]

Standing these two words side by side and we can clearly see these are two different words.

Legal vs Lawful

dictionarydotcom is not a legal source. Also can't use a word to define itself. See: Fiction of Law from a legal source.

It's so self evident it's ridiculous. Legal imitates from law. Legal is to be given the force of law, because it does not possess that force on it's own. Legal requires government to make it Law.

And the fact that you don't get it does not surprise me one bit...

Taking a life is murder whether it is lawful or not.
I shot the sheriff(but I swear it was in self defense).
Therefore I am a murderer and have committed a capital offense.

[chrisfully]

This guy kind of sounds like Petyr Baelish.  Don't know whether or not to trust him...

[Mtaalas]

Logically valid arguments might not be factually valid. :D

[Hirsutecyclist]

Great. Now I must play 2 hours of blitz. :(

[nicholasmartinez]

murder and abortion are two different words of course they aren't the same.
Taking a life is murder whether it is lawful or not.
what mtaalas said.

You are on the no abortion side soz never mind.
