Hi there,

I am on Chapter 6 of the Logical Reasoning Bible and although I understand the concept of Premises/Conclusions and Sufficient/Necessary clauses separately, I am wondering what the relationship is between the two structures? I feel like now as I am reading through the stimulus, I am spending too much time trying to identify what each piece is, and I don't understand namely how sufficient/necessary clauses relate to the conclusion. Is there overlap? Is the necessary clause always a conclusion (or at least a sub-conclusion)?

Thanks,
Erin

Erin,

This is a very good question, and one I've never been asked before. :)

Generally, a sufficient/necessary or conditional clause is a premise. That's because it is a factual relationship that someone is asserting. Another premise would then be needed in order for you to draw a conclusion.

Consider the following example:

Premise 1:
If an animal is a dog, then it's a mammal.
animal is a dog --> mammal
(sufficient) ---> (necessary)

Premise 2:
That animal is a dog!

Conclusion:
That animal is a mammal.
--------
As you suggest, there is a relationship between the premise-conclusion relationship and the sufficient-necessary relationship because a sufficient-necessary clause can interact with other parts of the question to allow you to draw a conclusion.

I hope this helps!
