I can love only what I can place so high above me that I cannot reach it.

There has never been a time in which I have been convinced from within myself that I am alive. You see, I have only such a fugitive awareness of things around me that I always feel they were once real and are now fleeting away. I have a constant longing, my dear sir, to catch a glimpse of things as they may have been before they show themselves to me.

If I shall exist eternally, how shall I exist tomorrow?
