5_6192566572737889031 structure of argument
1. Day 1:
• Understanding the structure of arguments:
– Argument forms,
– structure of categorical propositions,
– mood and figure and
– classical square of opposition
2. Proposition
• Every complete sentence contains two parts:
– a subject and a predicate.
• The subject is what (or whom) the sentence is about,
• while the predicate tells something about the subject.
Ex, Some dogs are White
• Dogs – Subject
• White –Predicate
Note: Proposition –Statement-Premise
3. Argument:
• The premises of the Argument is the first two
statement, and the last statement is a
Conclusion.
• The statements of premises support the
statement of conclusion.
• This type of arrangement is called an
Argument.
4. Structure of Argument:
All Roses are Red Premise 1
All Red are Blood Premise 2
All Roses are Blood Conclusion
5. Forms of Arguments
There are three types of Arguments:
1. Deductive arguments
2. Inductive arguments and
3. Abductive arguments
6. 1. Deductive Argument
• An argument where the truth of the
premises guarantees the truth of the
conclusion.
• Example:
Premises: All man are good
Kalam is a man
Conclusion: Kalam is good
7. 2. Inductive Argument
• An inductive argument will not be deductively
valid, because even if a pattern is found many
times
• Therefore, an inductive argument provides
weaker, less trustworthy support for the
conclusion than a deductive argument does.
• For Example:
Premises: I have seen 1000 birds, and
All of them have been white
Conclusion: All birds are white.
8. 3. Abductive (Hypothetic) Argument
• Abductive arguments seem to make an even bigger
jump than inductive arguments. Inductive arguments
generalize, while abductive arguments say that
successful predictions “prove” theory is true.
Abductive arguments are not deductively valid because
false theories can make true predictions. So, true
predictions do not guarantee that the theory is true.
• Example:
Premises: These coins conduct electricity (fact)
If these coins are made of gold (hypothesis)
then they would conduct electricity (prediction).
Conclusion: These coins are made of gold.
12. Symmetry:
• Symmetrical:
– A is = B
– So B is = A
• Asymmetrical:
– A is > B
– So B is not > A
• Non symmetrical:
– A is the sister of B
– So B is may or may not be sister of A
13. Transitivity:
• Transitive: Relationship travels from A to C via B
– A is = B
– B is = C
– So A is = C
• Younger to, Precedes, Succeeds and ancestor of
• Intransitive : Relationship not travels from A to C
via B
– A is father of B
– B is father of C
– So A is father of C is invalid
• Son of
15. Which one of the following is the characteristics
feature of an argument? (6th Dec 2019-1st Shift)
(1) It is neither true nor false
(2) It is either true or false
(3) It is neither valid nor invalid
(4) It is either valid or invalid
16. The premises of a valid deductive argument is?
(December 2008)
(1) Provide some evidence for its conclusion
(2) Provide no evidence for its conclusion
(3) Are irrelevant for its conclusion
(4) Provide conclusive evidence for its conclusion
17. Structure of a categorical Proposition:
Quantifier + Subject +Qualifier + Predicate
Example:
All Roses are Red
Quantifier Subject Copula Predicate
18. A- type E- type
All No
(Universal (Universal
Affirmative) Negative)
I- type O-type
Some Some not
(Particular (Particular
Affirmative) Negative)
19. A-type: All, Each, Every, Any, Only, The, An,
Noun, Pronoun
E-type: No, Neither, Never, None, Not
I-type: Some, A few, Certain, Most, Many,
Almost, Few
O-type: Some not, Hardly, Every not,
Majority not, All not
21. “Some students are sincere” is an example of
which proposition? (2nd Dec 2019-1st Shift)
(1) Universal negative
(2) Universal affirmative
(3) Particular affirmative
(4) Particular negative
24. Important terms:
Minor term:
• Subject of
conclusion
Ex.,
All Roses are Red
Roses = Subject
Roses =Minor term
Major term:
• Predicate of
conclusion
Ex.,
All Roses are Red
Red = Predicate
Red =Major term
25. Important terms:
Middle term:
• It appears twice or
• It presents in both the statements
but not in conclusion
Ex.,
All Roses are Red
All Red are Blood
Therefore All Roses are Blood
Middle term = Red
26. Steps in Mood & Figure:
Step 1 – Make argument in standard form
Step 2 – Determine the Mood
Step 3 – Determine the figure of the Argument
Step 4 – Check the validity
Conditional Unconditional
27. Step 1:
Standard form:
• Write Major premise and minor premise
• In standard form the subject of the
conclusion must come from the minor
premises and predicate of the conclusion
must come from major premises
28. Given Form:
All Roses are Red = Statement 1
All Red are Blood = Statement 2
All Roses are Blood = Conclusion
Minor Major
term term
Standard Form:
All Red are Blood = Major premise
All Roses are Red = Minor Premise
All Roses are Blood = Conclusion
29. A-type: All White are Milk
E-type: No White are Milk
I-type: Some White are Milk
O-type: Some White are not Milk
To predicate mood always look at standard form equation
St 1:All Red are Blood
St 2:All Roses are Red
Con :All Roses are Blood
Which means Mood is AAA
Step 2:
30. • Position of the middle term = Figure
St 1:All Red are Blood
St 2:All Roses are Red
Con :All Roses are Blood
Step 3:
31. Step 3:
Figure 1 Figure 2 Figure 3 Figure 4
M P P M M P P M
S M S M M S M S
33. Given Question:
All Roses are Red = Statement 1
All Red are Blood = Statement 2
All Roses are Blood = Conclusion
Standard Form:
All Red are Blood = Major premise
All Roses are Red = Minor Premise
All Roses are Blood = Conclusion
Answer:
Mood is AAA
Figure is 1
34. Consider the following argument (4th Dec.2019)

What is the mood in the above syllogism
A. IAI
B. IAA
C. IIA

41. Contradictory Statements:
• A-O, E-I contradictory Pairs
