Belief in looking unmoved when given a rise? (5)
I believe the answer is:
tenet
'belief' is the definition.
(synonyms)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for tenet that I've seen before include "Conviction" , "That's the law" , "A belief or creed - a palindrome" , "Teaching" , "Canon" .)
