“In reality a man cannot forget anything. He may have a lapse of memory; he may not be able to recall at the moment a thing that he knows or words that he has spoken; he may not have the power of his will to call up these events and words; but let God Almighty touch the mainspring of the memory and awaken recollection, and you will find then that you have not even forgotten a single idle word you have spoken.” (Joseph F. Smith, Man, His Origin and Destiny, pp. 358-360)
“Man himself is a self-registering machine, his eyes, his ears, his nose, the touch, the taste, and all the various senses of the body, are so many media whereby man lays up for himself a record which perhaps nobody else is acquainted with but himself; and when the time comes for that record to be unfolded all men that have eyes to see, and ears to hear will be able to read all things as God himself reads them and comprehends them, and all things, we are told, are naked and open before him with whom we have to do.” (John Taylor, Journal of Discourses 26:31)
