Oh really what were the bases given by Falma before he brought his brother to his pharmacy, whose entire existence was keep hidden from him?
What people have been trying (and failing by the looks of it) to tell you is that a proper scientist/physician (who Palle is
supposed to be, based on his pedigree) should not react emotionally to most any (scientific) claim, even if they sound preposterous at first,
especially if they come from someone you claim to care about.
I've had complete strangers come to me with claims of working
perpetuum mobile several times in the past; I humored
them by taking a look at their diagrams and specifications, before dismissing them and trying to explain why their designs wouldn't work. So if my 12-year old brother came to me and claimed he had solved the three-body problem, or proved the existence of faster-than-light particles, or some other similarly fantastical claim, I would be
highly skeptical, but would
at least take a look at his working before moving to the hard-truths lesson.
What I
wouldn't and
shouldn't do as an older brother and as a trained scientist is rip his notebook out of his hand, tear it to pieces, slap him across the face and call him a snot-nosed brat who can't possibly do anything, which is what Palle has essentially been doing until this chapter.
You also seem to assume that Palle is wholly dependent on information ("bases") provided by Falma, when as someone
supposedly trained as a scientist it
should have been second nature for him to seek and verify info from many other sources. Using the little brother analogy again: if my 12yo brother claimed to have graduated highschool, all I would need to do is to ask, "which school? when?" and call the school. Or ask our dad. Or our mom. Or I could even just wait for him to show me his diploma, then google. Palle, dumbass that he is, did nothing and instead fixated on the perceived impossibility for Falma to be able to achieve anything.
