Memory and forgetfulness are as life and death to one another. To live
is to remember and to remember is to live. To die is to forget and to
forget is to die. Everything is so much involved in and is so much a
process of its opposite that, as it is almost fair to call death a
process of life and life a process of death, so it is to call memory a
process of forgetting and forgetting a process of remembering. There is
never either absolute memory or absolute forgetfulness, absolute life or
absolute death. So with light and darkness, heat and cold, you never can
get either all the light, or all the heat, out of anything. So with God
and the devil; so with everything. Everything is like a door swinging
backwards and forwards. Everything has a little of that from which it is
most remote and to which it is most opposed and these antitheses serve to
explain one another.
