LessonsProof: Syllogism, Induction, Analogy and the Four FiguresQuiz

In a syllogism (qiyās), premises are arranged so that accepting them entails a determinate conclusion. The conclusion is not a mere guess; it is required by the logical relationship between the premises.

Example:
Every human is mortal.
Zayd is human.
Therefore Zayd is mortal.

If the premises are true, denying the conclusion would conflict with them. The distinctive feature is consequence by necessity, not simply placing several sentences together.
