so...There are three types of deductive logic.
-syllogism
-modus ponens
-modus tollens
1. Syllogism is a bringing together of two statements to arrive at a conclusion.
- of the two statements one is a generalization and the second is a specific factual statement related to the general statement
- the conclusion brings these two statements together
- no new substance is brought into the conclusion
- heres a comic i found...
2. Modus ponens is Affirming the Antecedent, where X is the antecedent which is affirmed as true.
- If X is true then Y is true.
X is true.
Therefore Y is true. - an example would be ... If you repent, you will go to heaven. You have repented. So therfore you will go to heaven
3. Modus tollens is the root of falsification.
- If X is true then Y is true.
Y is false.
Therefore X is false. - an example would be... If there is smoke, there is fire. There is not fire, so there is no smoke.
done :P
