I am pessimistic because I don't trust history. But at the same time, I am optimistic. Out of despair, one creates. What else can one do? There is no good reason to go on living, but you must go on living. There is no good reason to bring a child into this world but you must have children to give the world a new innocence, a new reason to aspire towards innocence. As Camus said, in a world of unhappiness, you must create happiness.
