Chapter 6 Section B: Part 3-Valid and weak forms of arguments using conditionals

I will be discussing valid forms of arguments using conditionals. Remember, a conditional claim is “one that can be rewritten as an ‘if…..then….’ claim that must have the same truth-value.” There are two forms of arguments that are valid using conditionals. These are direct and indirect. A direct example of a valid reasoning with conditionals can be described as “If A, then B. It is A. So then it is B.” For example:
If you punch Jacob, he’s going to punch you back.
You punched Jacob.
So He punched you back.
This is valid because it is impossible for the premises to be true and the conclusion false.
An indirect example is the exact opposite. “If A, then B. It is not A. So it is not B.” For example:
If you punch Jacob, he’s going to punch you back.
You didn’t punch Jacob.
So He didn’t punch you.
These are the two ways to form an argument using conditionals. Hope that helps a little bit!
