Ayn said that what one needs for nonfiction writing is what is needed for life in general: an orderly method of thinking. Writing, she said, is literally only the skill of putting down on paper a clear thought, in clear terms.
She discussed subject and theme, creating an outline, writing the draft, floating abstractions, editing, style, book reviews and introductions, writing a book, selecting a title, and acquiring ideas for writing.
She contrasted an active psycho-epistemology (i.e. method of thinking) with a conforming one. She discussed the only way to learn, the only way to be independent. She stressed independent thinking and principles.
