Inventing places

I read The Shadow Lines by Amitav Ghosh and wanted to preserve this bit: " I could not persuade her that a place does not merely exist, that it has to be invented in one's imagination; that her practical, bustling London was no less invented than mine, neither more not less true, only very far apart. It was not her fault that she could not understand, for as Tridib often said of her, the inventions she lived in moved with her, so that although she had lived in many places, she had never travelled at all"
