The thing I really like about the idea of outlining is that it sort of forces you to confront the "how" of how you are organizing thoughts. You have to have a context and and theory in order to make it make sense.
For example I see the term "top-level item" used in outlining to discuss starting points,
In this version, I suppose the top level items would be:
1 - The Life of Epicurus
2 - The Philosophy
So the basic structure is that you're breaking things down into those two categories.
Then under philosophy you have:
A. Cosmology
B. Epistemology
C. Ethics
And then the great weight of the outline is under Ethics as:
1. Pleasure is the natural innate goal of human (and animal) life
2. The Tetrapharmakos
3. Correct Understanding of Justice
4. A Pleasurable and Content Life
With Item 4 being the great weight of that section.
I am just thinking out loud about the process. I wonder if an outline needs a sort of topic sentence foreward to describe how it is organized before the organization actually starts. Is the outline: (1) How I Think I Should Live? or (2) The Important Aspects of Epicurus, or (3) What I Would Say To A Friend About Epicurus If I Only Had Five Minutes .... or something like that.
So we've been talking about this section as "Personal Outlines of Epicurean Philosophy" but maybe that's too broad of a title? What makes sense as a way of putting the goal of the outline out there with clarity?
