> Is it correct to ask about the idea of a table? i.e. is there such a thing as a table in the abstract?

If you rephrase the question as, "Is there such a thing as a more real table than this table?", or if "Ceci n'est pas une pipe" sparks joy (or puzzlement) in your heart, you might enjoy reading Neal Stephenson's Anathem.

I can't write why, for spoilers. I can say the book is heavily inspired by Platonism, as well as many other things. If a science fiction story about philosophical monks, astronomy, and adventure appeals to you, give it a read.
