The other two had already resulted in untold unendurable miseries and horrors." "Yes, the botched worlds," Oktav interrupted bitterly. "How many of them have there been, Prim?

What crime have they committed save that of guessing wrong, when, by your admission, all was guess-work? What difference is there between the main trunk and the lopped branches, except your judgment that the former seems
