Golden mansions are to be found in books

Golden mansions are to be found in books is a proverb that Young Lillie invokes while asking Jan Liseiwicz to let Rong Jinzhen read his mathematics books. In the exchange, it gives a memorable image to Lillie’s practical case for education: books offer access to knowledge already established, which can prepare Jinzhen to pursue worthwhile unknowns of his own.

Educational Argument

Young Lillie has just argued that Jinzhen’s unusual inventiveness is partly a consequence of lacking ordinary foundational knowledge. As an example, he points to Jinzhen using a mirror to light his way rather than choosing a simpler available tool. Lillie does not dismiss the ingenuity; he worries that, without study, Jinzhen may keep spending his talent on unusual routes to results others can reach by simpler means. Learning what has already been done, he argues, would give Jinzhen a stronger basis for original research.

The Appeal to Books

The proverb concludes Lillie’s request that Liseiwicz make an exception and allow Jinzhen to use the library he brought back from his travels. Lillie recalls seeing a notice on the shelf discouraging requests to borrow the books, so the appeal acknowledges that access is not ordinarily offered. By invoking the proverb, he frames lending them not simply as a favor but as a way to support Jinzhen’s education. The image of books as a source of riches thus turns the library from guarded property into a potential resource for the young mathematician.
