Quantifiers Questions - - Question 5

Linda says that, as a scientist, she knows that no scientist appreciates poetry. And, since most scientists are logic...

Why are logical and illogical not opposites?

When I had originally mapped out this question I wrote illogical as not L, or not logical. Can you explain why you cannot make this assumption? It seemed that in other questions these types of binaries were encouraged to make the question variables similar?

I got to the right answer too, but I am wondering when it say no scientist, can I put S with a Slash through it? Because in the video the girl did the exact opposite.

@shafieiava,

It is fine to use ~L to diagram illogical.

The proper way to diagram the statement "No scientist appreciates poetry" is

S -> ~P

IF one a scientist, THEN he does NOT appreciate poetry

or

P -> ~ S
IF one appreciates poetry, THEN he is NOT a scientist.

Does this make sense?

Let me know if you have any other questions.
