What is the Law of Detachment?

Back

The Law of Detachment states that if a conditional statement is true and its hypothesis is true, then the conclusion must also be true.

What is the Law of Syllogism?

Back

The Law of Syllogism states that if "If P, then Q" is true and "If Q, then R" is true, then "If P, then R" is also true.
