conditional logic

[jayparkcom]

Please refer to Prep test 52 #17

it's a sufficient assumption question...

The conclusion says "thus it is imprudent to appear prudent."

I diagrammed this as imprudent -> appear prudent.

However, some people suggested that diagramming that as

appear prudent -> imprudent.

I thought "is" acts as the arrow but I guess not.

Someone help me out why it's the case?

===============

Hey, hey. I felt like you just contradicted yourself there. You are correct, "is" acts as the arrow.

So when we see "thus it is imprudent to ...",
we have to put 'imprudent' after the arrow, since 'imprudent' is after 'is'.

--> imprudent

Then we just grab the other idea and put that on the left.

appear prudent -> imprudent

Consider these two identical statements:
"It is wrong to lie."
"Lying is wrong"

In both cases, the "is" precedes "wrong".

In both cases, we need
Lie --> Wrong

The alternative,
"Wrong --> Lie" means that ANY time you do something wrong, it must be lying.

Hope this helps. Let me know if you have unresolved qualms.
