People are already correcting you, but I find it hard to read this much into the case of this particular text. We'd need to know the full context to what exactly happened, but they might have chosen to sacrifice the catalog for many reasons, not just because of an anti-scientific bend. Maybe it was one of many copies that they held, yet the other ones didn't survive.

We also need to consider that these sorts of texts did survive because of monks. They kept the embers alive. Without them, we would have nothing, not living among the stars.
