Being eighty-five, I am an oldest child of the century which is being reviewed in this lecture series. I have lived through this stormy epoch from my childhood until today and may therefore qualify as a witness. Not a witness who presumes to speak as an expert about political and social events, but as one who may recall what has happened in order to raise the question what philosophy, the area about which I do have something to say, has to do with our situation, with our fears, our hopes, and our expectations.

It may also mean something when I recall how the first Zeppelin filled us with wonder, this cigar floating in the sky. It was the case that one began even as a child to feel something of the time, of its self-consciousness, its beliefs, also its hopes, and certainly also its fears. As is the way with children, it was mainly the occasional subtle earnestness in the words of my father that led me to feel that not everything was at its best in the world. So I will not forget the moment of the outbreak of the war in 1914, when I enthusiastically cried out with the frivolity of____________________
