Foundation less fantastical than Dune?!?!
Pyschohistory is no more scientific than prescience. One just pretends to be based on math, the other genetics. Also, psychics and empaths and hive minds, oh my!
Come on man.. lay off the disrespect a little. So far i enjoyed your posts here as a fellow Dune and SF fan so don't sour the experience.
Of course Psychohistory is nothing that really exists, it's a SF concept that was given a pseudoscientifc layer to make it sound believable. The same has been done for ages in SF and Star Trek is infamous for its technobabble.
With Dune it appears that it's much more esoteric and mystical when you think about it which is fine for me - it made for some very cool concepts and action pieces and the same applies for Foundation (and i seem to have missed all the Gaia stuff as i only read the original trilogy that only handles the Mule).
