19
Q

Unknown relationships in square of opposition for contraries

A

If one is false, it implies nothing about the truth or falsity of the other

20
Q

Unknown relationships in square of opposition for sub-contraries

A

The truth of one implies nothing of the truth or falsity of the other one

21
Q

Unknown relationships in square of opposition for sub-alternations

A

The falsity of the universal implies nothing about the particular, and the truth of the particular implies nothing about the universal

22
Q

All A is B is the

A

Universal Affirmative

represented by A

23
Q

No A is B is the

A

Universal Negative

represented by the letter E

24
Q

Some A is B is the

A

Particular Affirmative

represented by the letter I

25
Some A is not B is the
Particular Negative | represented by the letter O
26
Saying B belongs to all A is saying
All A is B
27
Saying B is predicated by all A says
All A is B
28
Order of first figure syllogism
B is A-Major premise C is B-Minor premise Therefore C is A
29
Order of second figure syllogism:
No N is M-Major premise All O is M-Minor premise Therefore No O is N
30
Order of third figure syllogism:
All S is P-Major premise All S is R-Minor premise Therefore Some R is P
31
In the syllogism, the conclusion is always stated in this order:
``` Minor term predicated Major term, I.E. A is the Major term C is the Minor term B is the middle term All B is A (Major premise) All C is B (Minor premise) Therefore All C is A(Minor then major) ```
32
First figure syllogisms that work:
AAA (All B is A, All C is B, All C is A) EAE (No B is A, All C is B, No C is A) AII (All B is A, Some C is B, Some C is A) EIO(No B is A, Some C is B, Some C is not A)
33
Second figure syllogisms that work:
EAE (No N is M, All O is M, No O is N) AEE (All N is M, No O is M, No O is N) EIO (No N is M, Some O is M, Some O is not N) AOO (All N is M, Some O is not M, Some O is not N)
34
Third figure syllogisms that work:
AAI (All S is P, All S is R, Some R is P) EAO (No S is P, All S is R, Some R is not P) IAI (Some S is P, All S is R, Some R is P) OAO (Some S is not P, All S is R, Some R is not S) AII (All S is P, Some S is R, Some R is P) EIO (No S is P, Some S is R, Some R is not S)
