Hi Martin - I cannot get my mind wrapped around 0 statements and how the predicate is distributed.
An example/diagram of Some Dogs are not long-haired things.....can you put that in other words? The quality of long-hairedness applies to things other than dogs...
I think I understand No dogs are longhaired things. Because you have a circle of all the dogs in the world and you have a separate circle of all the long-haired things in the world....I can picture that..

But this case...I can't

I'm dense and I have to teach this tomorrow!

Maria,

When you say, "Some dogs are not long-haired things, you are saying that some dogs (particular-undistributed) are excluded from the WHOLE CLASS (universal-distributed) of white things. Only a part of the circle of dogs will be shaded because you are only talking about some dogs, but the whole circle of white things will be excluded from the shaded area, because that part of the circle of dogs that is shaded is outside the whole circle of white things.

The dogs that you are referring to (ones that are not white things) is outside the entire circle of white things.

I hope that helps.

Martin
