How do you diagram this statement? Forum

Fish have the capacity to swim and think. Since exactly the same applies to elephants, elephants are a type of fish.

Do I need to represent both "swim" and "think" as separate variables when diagramming, or do they get combined into one?

doesnt matter

[IHaveDietMoxie]

it depends. For this its fine to do them together. In some cases it might be important to parse.

F > ST

E > ST

therefore E=F

mistake is that necessary(ST) is not sufficient for F

Thank you! Also, what is the best and most accurate way to represent the conclusion here? The Powerscore Bible doesn't make a reference to any equals sign or notation similar to it, so I just used a standard If/Then arrow (though I was fairly certain it was incorrect).

i just did that equals sign ad hoc. I don't know what the accepted way to do that would be.

Actually, its basically a categorical syllogism.

All F are S and T(class of animals that can swim and think)
All E are S and T
therefore All E are F (obviously there can be animals that can both swim and think but not be F)

also don't expect powerscore to be comprehensive, it will fail you.
