How we change what others think, feel, believe and do

Non-sequitur Fallacies

Disciplines > Argument > Fallacies > Non-sequitur Fallacies

When one thing follows another in a predictable sequence, it gives us a way of creating a valid argument. However, when we make the assumption that there is a 'Y follows X' relationship, yet this is not proven (even though it may be 'common sense'), then we are making a Non-sequitur fallacies (literally 'it does not follow').

Affirming the Consequent: If A then B. B is true, so A is true.
Denying the Antecedent: If A then B. A is false, so B is false.
In a Certain Respect and Simply: Extending assumed boundaries too far.
Logical Inconsistency: Arguments that contradict one another.
Missing the Point: Drawing the wrong conclusion.
