Hi friends!
Can anyone post all the rules regarding syllogisms with an example, in a step by step procedure. These are tough to me.

A - S, SS - D conclusion A - D follows from Raval's notation second conclusion SS /AA is straightaway ruled out by Raval's notation. Raval's notation is new simplest and quickest way to solve syllogism problems at a glance. Search 'raval notations at philpapers' in google and find complete new and simple approach published at University of London.

I want to know these 2 crucial facts about syllogism: First, we all know that 'No and Some'/'Some and some not' form an either case or a complimentary pair, but does 'All and No' form a complimentary pair...Second, what is the difference in approach of these two statements:
1.All stones are glass.
2.All stones being glass is a possibility.
1.All stones are glass.
2.All stones being glass is a possibility.

In second diagram its shown all actors are dancer.
In first some actor are dancer.
If both possibility are true then only conclusion occurs.
So neither 1 nor 2 should be the answer.
Why conclusion I is selected?
In first some actor are dancer.
If both possibility are true then only conclusion occurs.
So neither 1 nor 2 should be the answer.
Why conclusion I is selected?

@Yamuna. I am unable to understand about interference and conversion, can you explain it in a different way ?

Hai. friends
Actually syllogism has ,the statements could therefore be classified into the following two types
a) universal propositions like"all" or " none"
ex: All lecturers are research scholars.
No student refers to research study material.
b)particular propositions like " some" or "some...not"
eg: Some vehicles are cost prohibited.
Some roads are not good.
And the syllogism statement has two types
Interference and Conversion
In interference.. there is no change in subject and predicate.
for ex:
in contraverse, conversion has interchanged their subject and predicate.
there is some simple formula that is easy to memories
Denote "All as A"
"NO as E"
"Some as I"
"Some ..not as O"
formula,
In interference
A=A
E=I
In Conversion,
A=A
E=E
I=I
Eg:
1.All Students are music lovers-A
NO music lover is cruel- E
(Here "All denotes A
so A=I and E=O)
Answer: (Interference)
Some students are music lovers
Some music lover are not cruel
(here, no change in subject(students) and predicate(music lovers)
(In Conversion)
Some music lover are students
No cruel is music lover
(here there is change in subject and predicate)
