Overview
An argument from authority is any argument based solely on the credibility of a particular entity (the authority).
The presumption of credibility may proceed from any of several other presumptions, including:
- The authority is the definitive source for knowledge on this subject, so any statement s/he makes on this subject is true by definition or is the official truth
- The authority knows more than you do, so any counter-arguments you might propose are based on ignorance
- The authority is infallible and incapable of error
Synonyms
- ipse dixit (Latin: he himself said it)
- argumentum ad verecundiam (Latin: argument to respect)

- "God says homosexuality is a sin, so it must be."

Notes
As a rhetorical tool, this argument often succeeds in shifting the debate from its original topic to a discussion of the merits of the cited authority, which can easily slide into ad hominem attacks ("you said so-and-so is wrong, well that just proves you're wrong!").
