In this epitomized form our previous psychical life exists for us even more than the external world, of which we never perceive more than a very small part, whereas on the contrary we use the whole of our lived experience. It is true that we possess merely a digest of it, and that our former perceptions, considered as distinct individualities, seem to us to have completely disappeared, or to appear again only at the bidding of their caprice.
