Appeal to consequences
An appeal to consequences is a logical fallacy in which the truth of a proposition depends on its consequences:
- If A is true, than B. B is good, therefore A is true.
- If A is true, than B. B is bad, therefore A is false.
The latter form is the argument from adverse consequences. In fact, the appeal to consequences is simply a generalized form of the argument from adverse consequences; desirable as well as undesirable outcomes are included.
Appeal to consequences is a logical fallacy for the simple reason that wanting something to be true does not make it true.
- "Religion promises an eternity in heaven. Don't you want to go to heaven?"
- "God must exist because my life would be meaningless without him."
