Cannot
You cannot write about what you do not know. On the other hand you can write about what you know only a little.
I may never have had a romantic love but I have looked at my grandparents and seen it and looked into my family's eyes and known a different type of love, hence I know what love is. I know a little about phycology and a bit less about yoga, but I know they exist so I can write about them. A topic I know little about in school I can research, but I must first know the topic exists and as I read I learn. Even the characters in a novel I am writing must first introduce themselves in my head and tell me their story before I can put it on the page.
Their are probably things in this world that I know nothing about, a ritual from another country or an important book I have never heard of. About these things I cannot write for do not know. How can I write a story I do not know needs written?
