I've been thinking of this idea while in B&N reading a philosophy book (I forgot which exactly, I think it was Voltaire's dictionary).
First off... Does anyone keep some sort of .. "Philosophical idea journal" or anything?
How did historic philosophers (I mean, post-Socratic.. like 1500+ AD) write their books? How do they write their books today? Do they keep a journal with questions and write down their views on them or something?
