Maybe it's not death that is the mother of beauty, but the nakedness that we can't hide from, either. But, a larger picture view and the application of reason dispute such interpretations. It is a logical conundrum that Mormonism accomodates by various ex post rationalizations. Socialization within the church reinforces this belief regularly. To equate personal revelation with science is a false comparison.
Science moves forward because it is verifiable.
It is testable. Different persons applying the same methods reach the exact same results. If I make a scientific claim, my claim is only accepted if it is replicated and validated by others. Absent this, my claim does not stand. And, the methods used to test claims are objective, transparent, and replicable.
