I'm still skimming through the article on my mobile, so I haven't read it all, but I think "the problem of induction" by Hume is the core of the dilemma.
Russel on the problem: The farmers' chicks get fed every day since birth. They infer that since tomorrow is a new day, food will be brought tomorrow. And that reasoning is indeed true: every time they wake up there's soy beans... Until one day the farmer wrings their necks.
