3ngel: thanks for the reply; i think that you stated your point of view very well; indeed it is a good theory; however i don't agree with you over this matter, but sadly i lack the necessary language skills to explain my arguments (only if someone would understand romanian :) ). in short, my opinion is that while Leto understood that the Scattering that will happen after his death will cause the spirit of the human civilization to reborn, he did not foresee that there will be also a Return from Scattering. From my point of view the Scattering was supposed to be the ultimate colonization of the Galaxy, a method of freeing the human civilization from the psichological cages of the concept of "The Empire", and Leto didn't think that somebody in the near future ( 1500 years after his death is a small period of time if compared to Leto's reign) would return to throw the humanity back inside those "cages". again, sorry for my bad english
