Dear Marion, It is with considerable embarrassment that I am constrained to admit that on matters of epistemology you and I are in substantial agreement. My presumption of extraordinary insight has faltered. After flapping his arms on the porch roof of the Magdeburg city hall a certain number of times, Eulenspiegel gave up and confessed that he was unable to fly after all. Objective, public knowledge is essential to the survival not only of the race but of the individual, whose imperfect and sometimes unsatisfactory relationship to that knowledge is characterized: a) by the individual's limited capacity to understand, (e.g. the mathematics of quantum theory is beyond me,) and b) by the potential inadequacy of much (if not all) publicly acclaimed knowledge. (e.g. Lamarckian inheritance of acquired characteristics didn't pan out, and Alan Greenspan's Economics left something to be desired.) The crucial question: How do I cope with the potential imperfections of public knowledge? The answer: I can't: It's beyond me, as is the ability to flap my arms and fly; beyond me as is perfect memory; beyond me as is the immortality of the flesh, - never mind the spirit. Even Socrates' statement: "I am ignorant." won't fly, because of the clear implication that of his ignorance, he isn't so ignorant at all. I'm left with no recourse. I can't even write with impunity that I have a prediliction to flirt with Doubt about the Conceptual World. There's nothing left to do but to babble, or to write novels or legal briefs. Jochen
