"... there is no shame in not knowing. The problem arises when irrational thought and attendant behavior fill the vacuum left by ignorance."

Nothing, not even the best and noblest, can go on as it now is. Nothing, not even what is lowest and most bestial, will not be raised again if it submits to death. It is sown a natural body, it is raised a spiritual body. Flesh and blood cannot come to the Mountains [heaven]. Not because they are too rank, but because they are too weak. What is a Lizard compared with a stallion? Lust is a poor, weak, whimpering whispering thing compared with that richness and energy of desire which will arise when lust has been killed.
