Loose Writings Predicting Calamities - Harold B. Lee

"One more matter: There are among us many loose writings predicting the calamities which are about to overtake us. Some of these have been publicized as though they were necessary to wake up the world to the horrors about to overtake us. Many of these are from sources upon which there cannot be unquestioned reliance.

Are you priesthood bearers aware of the fact that we need no such publications to be forewarned, if we were only conversant with what the scriptures have already spoken to us in plainness?"

Writings like this, often popular among conservatives, should be considered "secondary questions" as defined by Lawrence Corbridge in his BYU speech, Stand Forever.
