1. Syllogism (Contains three terms: Minor Term, Major Term, and Middle Term)
3 propositions: two premises and a conclusion
2. The Minor Term (S); The Major Term (P); The Middle Term (M)
- is the Subject of the Conclusion. (The Minor Premise is the Premise containing the Minor Term)

- is the Predicate of the Conclusion. (The Major Premise is the Premise containing the Major Term)

- is the Term not in the Conclusion but in the Premises
3. All Men are Mortal. ->  Major Premise
Socrates is a man. -> Minor Premise
Therefore, Socrates is mortal. > Conclusion
• Men-M
• Mortal-P

• Socrates-S
• man-M

• Socrates-S
• mortal-P
4. In order for a Conclusion to be TRUE
- All Terms must be CLEAR. (Simple Apprehension) - All Propositions must be TRUE. (Judgment) - The Form of the Syllogism must be VALID. (Reasoning)
5. Checking the Validity of the Syllogism Syllogisms have Mood and Figure:
The Mood of a Syllogism is the sum of the three “types” of its Propositions:

• Example:
• All men are mortal - “A” (Universal Affirmative)
• Socrates is a man - “A”
• Therefore, Socrates is mortal - “A”
• Mood = AAA
