Exact Clairvoyance and Ideal Magic

This can be explained as follows: If you ask your selves; How do I judge the memory of an experience which I had twenty years ago? you will reply: I experience it like a shadowy thought. Through its very essence, however, this memory offers the guarantee that, we do not have before us an empty fantasy, but the image of something which we really experienced in the past during the course of earthly life. Even as memory in itself guarantees that it refers to something which really existed in the past, so the experiences of the night upon which we look back contain the guarantee that they have no meaning in themselves but point to something which lies in the future.
