Ladies and gentlemen, as you see I am a feeble old man and you must not therefore expect that I am now at the height of my productivity or even my wisdom. In any case it is somewhat dubious to claim to be at the height of one's wisdom. For all that, when one is such an old man, one can undoubtedly say: I have accumulated a great deal of experience. But in truth, my attitude towards you is really strange, as I would really like to learn so much from you. I would need to know how things stand with school today, what are the concerns of present-day parents, what are the concerns your sons and daughters have, and all of that which I no longer know. I have doubted whether I can feel qualified to speak about it. We have already agreed, otherwise I would like to prescribe it, that we hold a short discussion, so that I do not detain you too long as an audience.
