Spiritualists can also be wrong. They look at what materialists are doing (the whole robotic, cybernetic tree) and it looks like a horrific way to commit mass suicide.
I'm saying about another thing.
You see, there is a point in "spiritualists says robotic is horrifing, because reasons". But they can do robotics, because, well, "materialist technology can be replicated by anyone". That's ok, that's the very point of being materialistic.

Phylosophical blocks as they are is normal for me.
But, first of all, they should be in-ok with phylosophy. No-way will materialists actually ignore psi when it's appear, and events as they shown in teasers actually ARE the ways materialists will react to sudden psi. Yes, materialists will never say "it's god and spirits". But "we had sudden genetic jump and now we have psi"?
Secondly, I don't like declaring some ethoses "right" or "wrong" in phylosphical sense. If souls are actually exists, and materialists just plainly refuse them, they're wrong. It's not "it's horrible" or "it's not horrible", it's "you actually wrong, no matter how do I think about it".
Actually, also I don't like it because it because it make ethoses very narrow. They, actually, already are, but it's quite possible to ignore; with big roads to ascension it will be too noticable. I mean, if you actually ask real-life spiritualists, there will be different opinions about AI, including "it's impossible" and "it's a great gift to be able to grand divine spark to mechanised creations!". But now you'll be locked on narrow definition, no deviations. That's bad with xenophile militarists isn't able to actually invade to primitive worlds (or every xenophile being able to actually educate stone-age ones!), and that's bad here as well.
But, I'm afraid, it's seen as the very conclusion of "Wiz Doctrine" - when you're making ethoses "classes", a basic factor what can you do and what can't, and wants to block them to distinct playstyle, you'll have to make this ethoses narrow. Another way they won't fit into playstyle!
Yea and referring specifically to Babylon 5 (as Wiz and many others seem fond of doing) telepathy seemed to be a biological eventuality.
More about it - in B5 telepathy is actually ARTIFICIAL - Vorlons just put it there by biological upgrade. Narns, who are actually spiritual people, haven't psi, because all carriers of psi gene was killed. Humans, who are materialists
(personal - mostly, governmental - definitly), have.
