That is wrong though. Scientists aren't driven by irrational fears; they are driven by curiosity, in the main, to find out how stuff works. And in that regard the principle is to follow where the evidence leads. That isn't phobia, it is being true to the evidence.
They may be driven by curiosity but it is their phobia of 'supernatural' things that prevents them from integrating such matters into their world view.
If galaxies are moving apart at an accelerated rate, scientists assume that something is pushing them apart, even though we can see no evidence of any such thing. We then start looking for evidence for this something. This is Dark Energy....which is said to constitute 70% of the mass of the universe.
If we see some odd gravitational effects in the cosmos, scientists assume there is some exotic matter present everywhere that makes this happen, even though we see nothing of that sort anywhere. Then they start looking for evidence of this strange matter. This is Dark Matter....which is said to constitute 25% of the mass of the universe.
But if we see complexity and intelligence arising through biological evolution, we don't think that something should be making this arise....we attribute this to chance happenings. That's just the way things happen folks! Nothing to see here!
If we talk of a Soul or Consciousness, we are asked to outline in detail such things as the texture, chemical composition, how it bonds with the body and so on.
