Facepalm* Oh dear, logical validity has nothing to do with understanding the premises. I sincerely hope you buy a book on logic and study it.“whatever the premises mean, the conclusion’s invalid”???
HA ha ha ha ha ha!!!
Here a little tip, unless you know and understand the premise, you cannot determine the validity of the conclusion.
“An argument is valid if it would be contradictory (impossible) to have the premises all true and conclusion false. In calling an argument valid, we aren’t saying whether the premises are true. We’re just saying that the conclusion follows from the premises – that if the premises were all true, then the conclusion also would have to be true.” - Gensler, Harry J. Introduction to Logic. 2nd ed. New York Introduction to Logic. 12th ed. New Jersey: Pearson Prentice Hall, 2005. p. 682
