>Thanks Hilmar, I took it from that book of Asimov because I like it. I'll change the autor right now.
Asimov was one of my favorite authors, when I was a child. I have read several of his books, including "The gods themselves".
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
