Quote from : Roads to Berlin Book

When a memory fails to appear, it seems as though the time when it was created did not really exist, and maybe that is true. Time itself is nothing; only the experience of it is something. When that dies, it assumes the form of a denial, the symbol of mortality, what you have already lost before you lose everything. When his friend had said something similar to his father, his response had been, "If you had to retain everything, you’d explode. There’s simply not enough space for it all. Forgetting is like medicine; you have to take it at the right time.
