Appeal to consequences
From Iron Chariots Wiki
An appeal to consequences is a logical fallacy in which the truth of a proposition depends on its consequences:
- If A is true, then B. B is good, therefore A is true.
- If A is true, then B. B is bad, therefore A is false.
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."
- "One must be presuppositionally committed to Christ in the world of thought (rather than neutral) and firmly tied down to the faith which he has been taught, or else the persuasive argumentation of secular thought will delude him."
