Thanks Hilmar, I took it from that book of Asimov because I like it. I'll change the autor right now.

>Borislav, about your autoquote: "Against stupidity...", I have searched this on the Web, and seen it attributed to the German poet, Friedrich Schiller. I understand Asimov used it for the title of his book ("The gods themselves", divided in three parts, entitled: "Against stupidity", "the gods themselves", and "contend in vain"), but I think he didn't invent this phrase.
