In Ayn Rand's The Art of Fiction, which I'm still reading, Rand goes on and on about how the purpose of writing a novel is to put an abstract idea into concrete terms. The reader then takes this concrete story and draws the abstract idea from it. As I read this, I interpreted it as Rand essentially saying "show, don't tell," the most common piece of advice for writers these days.
I'm having a busy week, so I apologize for the brief post. I just wanted to share this with you as another perspective of writing fiction, besides the "show, don't tell" thing. Take your abstract idea and make it concrete!
Good luck with your writing, and see you on Friday!
