And the books on both virtual botany and real botany would still be more than a just a symbol manipulation game, they would have semantic content because there would be a correspondence between the way the symbols are manipulated and the way the virtual (or real) large photosynthesizing organism live. Regardless of if they are virtual or real if you want to know how trees live studying those botany symbols in virtual (or real) books will help, so they must have semantic content .
