889. CONTINUATION CONCERNING THE INTERIOR MEMORY That the interior memory is formed as are inclination, genius, understanding, and many other things in man, may be seen above [n. 888]; for whatsoever gives the faculty to the memory of particulars owes its proximate cause to the interior memory, but the faculty itself, regarded in itself, is of life. That there is an interior memory and of what quality it is can be perceived from the fact that in dreams, when the memory of particulars is not so aroused as in wakefulness, it is usual for a man to be presented such as he is, with all his features and with every condition of his body, his speech, his gait and like particulars. A man is never aware of these things from his memory of particulars, nor indeed can he describe any such faculty. In like manner we recognize the "animus" or variations of state of other people from their faces, also from the eyes and the region thereabouts, as well as from the tone of voice, and from many things which cannot be described. Man does not know whence he has learnt this, except from use alone, without knowledge.
