A Rough Outline is just that: a rough list of ideas that you think you might want to write about. As you research you will cross things out, add, and re-order your list, but researching without an idea of what your goals are, not only takes twice as long, but results in a paper that sounds like you do not know what you are doing.
Since you are researching from an outline, every card should be thoughtful and have a place. A rough outline with cards IS a rough draft of a paper.
I will be checking rough outline, typed outline, tally marks and cards. Bring cards to class so that we can start together as a class and you can work with your partner.
But the earlier phrase is actually "God is in the detail." While the "devil is in the details" means that there is often a mysterious unknown, "God is in the detail' means that we should look into things thoroughly. Both are appropriate here. Today we start note cards for symbols, characters, issues, events...the choice is yours. Whatever you choose, the details reveal both the heaven and hell that Remarque needs you to see.
