2487. I have been informed that the exterior memory regarded in itself is no more than some organic thing formed from the objects of the senses - especially those of sight and of hearing - within those substances which are the first origins of fibres. And it is according to the impressions left by those objects that the differences in form which are reproduced are effected. And those forms vary and change according to changes in state of a person's affections and persuasions. The interior memory is in a similar way something organic, though purer and more perfect. It is formed from the objects of interior sight, which objects have been organized into definite patterns within an order that lies beyond comprehension.
