A tiny question.

[Burgess, John]

I think HAG is taking a rather harsh line here... von Braun is not saying 
that "science prove" a spiritual existence... he's saying that his 
knowledge of science (which I think fairly considerable) reinforces his 
_belief_ in continued spiritual existence.  He is willing to take a 
scientific law and apply it to a field for which is was not created, 
i.e., to make a metaphore.  One may not care for his poetry, but that's 
what it is.  If the "truthfulness" of it doesn't strike a particular 
reader, then the poetic connection didn't work.

I don't see a "misapplication" of science in the quote.
