A belief is something you accept as true or real, often without needing proof. It can be about facts, opinions, religion, or personal values.
“Belief” comes from Old English “geleafa,” related to “believe,” with roots in words meaning trust or hold dear. Over time, its meaning narrowed to what a person accepts as true.
Beliefs act like mental lenses: they don’t just sit in your head; they change how you see everything else. Two people with different beliefs can look at the same event and honestly feel they saw different worlds.
