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.
