LDS Epistemology in Bullet Points

1. The definition of "Knowledge" is believing without doubt.
- Ether 3:19

2.  You have to WANT to believe in the proposition/principle.
-  Alma 32:27
(BTW, Alma 32's contribution to LDS epistemology is discussed further here)

3. You have to ACT as though you believe in the proposition/principle
- Alma 32: 28-34
