A syllogism whose every claim contains three terms each which occur exactly twice you nexactly two of the claims?
categorical syllogism
What is an OAE-1 syllogism?
An OAE-1 is a specific categorical syllogism. More accurately, it is representative of the Mood and Figure of the categorical syllogism. The OAE represents the Mood, which in this case is "Some M are not P, All S are M, and therefore All S are not P." The "-1" represents the Figure, which is determined by the location of the Middle term (represented by M). As you can see, this categorical syllogism is Invalid, because the conclusion that All S are not P is not necessarily true, even if both of the Premises (Some M are not P and All S are M) are true. Tl;Dr It's an Invalid Categorical Syllogism. Some M are not P All S are M ________________ All S are not P
What are the difference between affirmative syllogism to negative syllogism?
Affirmative Syllogism: All P are Q X is a P X is a Q Negative Syllogism: All P are Q X is not a Q X is not P Both syllogisms are always valid. but dont be fooled by their evil twins the fallacy of affirmation and the fallacy of negation.
Is the converse of the law of syllogism true?
Not always
How do you use the rules of inference to construct formal proofs?
The point of a formal proof of validity is to get back to the conclusion of a syllogism in as few steps as possible. Let's say we have the syllogism: 1. P>Q (that's supposed to be a conditional...) 2.P 3.Q>R /.'.R What you want to do is keep going with the syllogism. You can use steps 1, 2,and 3, but you cannot use the conclusion. How you use them is try to find which rules of inference start with any of your premises. For instance, step #1, P>Q and step #3, Q>R are the first two premises in the Hypothetical syllogism. So you could make step #4 P>R. Next to this step you will put what is called the 'justification', which would look something like this: 1,3 H.S. (which means: I used steps 1 and 2 and a hypothetical syllogism to make this step). Now we can use the step we just made in a Modus Ponens. This would use steps 4 and 2, and would look like this: R. Do you recognize that? That was our conclusion. We have now finished this formal proof of validity. Here's what the whole thing looks like: 1. P>Q 2.P 3.Q>R /.'. R 4.P>R 1,3 H.S. 5.R. 4,2 M.P. (If you want to look like you really know what you're doing, you will want to put Q.E.D. at the end of a formal proof. That's what the real logicians do). Hope this helps!! (By the way, I'm 13.) :D

Can a syllogism violate all five rules?
No, a syllogism cannot violate all five rules of a valid syllogism. The five rules (validity, two premises, three terms, middle term in both premises, and major and minor terms in conclusion) are essential for a syllogism to be considered logical. If all five rules are violated, the argument would not be considered a syllogism.
1 What makes something a syllogism?
