It was tough, but I actually resisted the urge and did not log on once the entire long weekend.
Anyway, I'm glad you're back, as I'd like to keep working on this thread.
I see. I'll go look that up ASAP.It can't be an A statement, because that is the "Universal Affirmative" statement, and 60% of a whole is not universal. This is a tricky one, because it is a combination of two types, I and O. That is, it expresses the I statement...

...but not exactly. That is because the logical quantifier "some" includes the case of "all". But, we are told a very specific "some" (60 percent) that most definitely does not include "all". So, the above also expresses the O statement...

This is called an "exceptive statement", and is discussed in the Logic Notes in the 12th post from the top (do a "control-F" for the word "exceptive" and you'll be taken right to it).
Hmm. I was close though .Almost. It is another exceptive I + O statement. "Almost all" communicates the idea that it is "some but not all"
Interesting point.Right. I would even go so far as to say that it is two E statements:
War is not healthy for children.
War is not healthy for other living things.
Since the predicate is compound, so is the statement. But, since we are not on Quantificational Logic yet the distinction is not yet important.
