RationalWiki's 2020 Fundraiser

There is no RationalWiki without you. We are a small non-profit with no staff – we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.

If everyone who saw this today donated $5, we would meet our goal for 2021.

Fighting pseudoscience isn't free.
We are 100% user-supported! Help and donate $5, $20 or whatever you can today with PayPal Logo.png!

Appeal to faith

Bad logic

An appeal to faith (or an appeal to belief) occurs when someone argues that you must first accept the truth of a statement in order to be able to rationally accept the truth of the statement.

The fallacy is a form of circular logic and an informal fallacy.


In reaffirming believers:

P1: I have faith that X is true.
P2: (unstated) Everything I believe is true.
C: X is true.

In shutting down nonbelievers:

P1: It is impossible to determine whether X is true unless you believe that X is true.
P2: You do not believe that X is true.
C: You cannot determine whether X is true.


See the main article on this topic: Faith

Faith, by definition, relies on a belief that does not rest on logic or evidence. Faith depends on irrational thought.

Furthermore, privileging a belief by saying that it is immune to criticism from those who don't accept it is special pleading and can never fail, making it circular logic.
