Nick,
You know, believes work on the basis of not knowing.
That's a general thing, since we actually do not know anything, and hence have no choice but hold beliefs about what we ate yesterday, how to thread a shoe lace, and the entire world we live in.
In general too, that's not a problem. As long as it 'works', who would have concerns about it?
Anyhow (i had already started a dissertation about belief systems, but thought better of it and deleted the lot), the thing with these two factions is that the first believe that VH might like to drink anything he would like to drink (a rather safe belief, wouldn't you say?), while the latter do have particular ideas about the matter (again, i'll spare you long - and short - explanations why they do).
You will be familiar with the phenomenon that the more unsafe, or 'risky' a certain belief is to adhere to, the deeper the conviction with which it is held is.
The high point of any such belief, the moment its over-worldly, i even dare say divine, truth is revealed, is when it becomes clear that it simply cannot be so as the belief would have it.
If it cannot be so in this world, it must be ... Right? Right!
Throughout history, a very short and easy to remember phrase was (and still is, because we haven't come up with something better) used for this, that nicely encapsulates all aspects of the phenomenon.
It's usually given in Latin, and goes: "credo quia absurdum".
Too long winded already, i know. I apologize.
So now to the point:
The lenient Hasselbladder faction does not really care what Victor Hasselblad liked to drink, since they think he would and should have drunk whatever he liked. And because he did, so will they.
And even if not, they will still.
The strict Hasselbladians faction hold this or that believe about what He liked to drink (you can see i'm rather a 'Bladder than a 'Bladian: the Hasselbladian creed will be quite specific, but i really do not care what the specifics are).
And if it would be discovered that He liked to drink, say, cold Darjeeling tea, instead of what they thought He would, they will still think that He would drink what they thought He would. And find their conviction strengthened that it indeed is so, by what anyone else would regard a rather annoying and sobering bit of news.
In short, neither faction would really care what Victor liked to drink.
