Vaild vs. Invalid Arguments
I had a question about the second example at minute 32:00 of the valid or invalid arguments. If we are to assume all premises are true wouldn't it make that a valid argument assuming every person named Sue is a girl?
Or am I wrong to think that we are to assume premises be true?
Thanks!

I think we assume they are true but by showing how the song made the premise false, we can see how we could attack the argument.

So we need evidence to prove a premise to be wrong?
Using the song as example, what if we have never heard the song or know any male named Sue? would we just assume the premise is true?

@karlasfalcon2 I am also confused by this example... I was reading in some other threads that Mehran was identifying ways to weaken an argument in this example and this concept would be explained in more detail later on... seems like he kinda just breezed by that because from everything I have been told, we have to assume the Premises are true in the world of LSAT. If a premise says pigs can fly, then pig's should fly.

Yes! We believe the premise is true until there is a premise or principle that could prove it wrong. This was an attempt to show that even though it may have been confusing
