YMMV / The Science of Discworld

• Anvilicious: It's indisputably the case that the "religion is bad / Belief Makes You Stupid" view in The Science of Discworld 3 gets hammered for all it's worth. Luckily, only the non-Pterry chapters are preachy, making them much easier to avoid.
• Fridge Brilliance: Early in IV, it's noted that the Church of the Latter-Day Omnians would "like to go back to Vorbis if they could". Now, other than brutally torturing "heretics" to death, what is Vorbis most notable for? His claim that "what appears to the senses is not the fundamental truth". In other words, insisting that all empirical evidence can be ignored in favor of the "deeper" truth, i.e. what Vorbis claims to be true. Which is exactly what the Latter-Day Omnians do: they continue to insist that the Disc is a sphere, despite the testimony of all the people who've seen that it isn't, and even when their god himself tells them it isn't, because their truth is, as far as they're concerned, truer than mere reality.
• Harsher in Hindsight:
  • While talking about why actual wizard magic on the Discworld is treated as a Fantastic Nuke in II, the narrator uses the expression "it has to be hard, because we know there's no such thing as a free goblin". At the time just an example of Hold Your Hippogriffs, this was years before Pterry would actually explore the plight of Discworld goblins in Snuff which included, among other hardships and indignities, being mass-kidnapped and exploited as slaves.
• Hilarious in Hindsight: While discussing implausible dinosaur-based Fossil Revival stories, the authors lament that nobody's ever made a film about bringing mosasaurs back from extinction. Some years later, Jurassic World did just that.
