You have a writing assignment for your philosophy class, and you need to generate a good topic to write about. You start by freewriting for a few minutes, and then you look back at what you wrote. You see a really interesting thought, and you write more about that thought for a few minutes. After you have repeated this process a few times, you are feeling pretty good about your ideas, and you start to outline a draft. What prewriting activity have you used to generate ideas for your writing assignment?
