Not all parrots have equally pleasant dispositions
my question is about the phrase "Not all parrots have equally pleasant dispositions"
in the diagram, it was written as "P-some-not EPD" which translates to "not EPD-some-P"
my question is regarding the "not" why is it behind the "EPD" instead of "Parrots"? looking at the statement it makes more sense that the "not" accompanies the "Parrot"
also, i dont understand why this is a quantifiers statement, the "all" indicates S&N and it introduces sufficient

Thanks for the question! So translate the statements back into English, and you might see why they make sense. The statement
P <—some—> ~EPD
just reads some parrots don’t have equally pleasant dispositions. Which means essentially the same thing as not all parrots have equally pleasant dispositions.
The alternative way of reading this is
~P <—some—> EPD
which means that some non-parrots have equally pleasant dispositions. That’s not really what the original statement means. You can think of the “not” at the beginning as “it is not the case,” so, “it is not the case that all parrots have equally pleasant dispositions.” In other words, “some parents don’t have equally pleasant dispositions.” The “all” doesn’t indicate S&N because it’s a “not all.”
Hope this helps! Feel free to ask any other questions that you might have.
