Hello, my name is Sam. I would like to ask a question of all writers and readers. At the beginning of many novels (or the chapters in them), there is one or several quotes. My question is, what is the true purpose of these quotes? It is it to condense the ideas or themes of the story? Is it suppose to convey a certain feeling or message? I am not sure if there is a grammarical(?) rule about a quote's purpose; I'm more interested in opinions anyway. Thanks!
