I would agree that we should save the art, literature, etc. But perhaps for a different reason.
The art objects are somewhat self-explanatory. Someone looking at them can appreciate the art, or perhaps hate the art. Or, to say it differently, they have a lot of stand-alone value. But works of science are not nearly so self-explanatory. The science is to be found in the knowledge of the scientists more than in their printed works. Those scientific works lack the same stand-alone value.
If we could take our best modern science textbooks, and somehow put them on a time machine to transport back to Aristotle, then I suspect that Aristotle would not know what to make of them. He would find some tantalizing hints. But he would probably see a lot of it as obviously wrong.
