# What do you call someone who is rigid in his beliefs?

Is there a word for telling a person is rigid in what he believes, and cannot be swayed into changing his beliefs? Someone who cannot be convinced by reason or facts? A religious person may fall into that category, but I want a generic term that doesn't only consider religious beliefs, but also scientific among others.

A few words that come to mind to describe someone rigid in their beliefs include being dogged, stubborn, uncompromising, dogmatic, hardheaded, obstinate, adamant, adamantine, or narrow-minded. If they are wrong, wrong-headed.

Dogmatic or prejudiced would fit.

(adj) (derogatory) Obstinate and stubborn to the point of stupidity.


Or obstinate

(adj) Stubbornly adhering to an opinion, purpose, or course, usually with implied unreasonableness; persistent.
