"A unique life. For some pessimists, part of the human tragedy is explained by how insignificant and irrelevant our individualities are. We think we are special, but we are not. And because we are irrelevant, we have all the more reason to suffer. This seems to me to be true. But it seems to me that existence is tragic, too, for the opposite reason. That is, because we are important. In the end one can ignore what is irrelevant and trivial. Doing that (ignoring the trivial) is not only easy, but to be expected. What is certain is that there is no time to waste on superficialities. But ignoring what is relevant, important and unique is different. Doing so is painful and can be humiliating for the ignored. One of the many tragedies of life is precisely this: that my precious life, my poignant, fragile, unrepeatable and unique experiences are ignored by the world. Life has given origin to my existence, has applied the principium individuationis to me (i.e., has placed me in a space and a time). And now it is the same life that disowns me, ignores me, leaves me alone, and will destroy me. Created to be ignored. That is our existential reality."
