Idea that Aristotle’s four causes might be a good organizing principle for a contemporary cook book: that dishes should be thought of as having material, efficient, formal and final causes — ingredients, recipe, presentation, satisfaction of appetite. (Or maybe: ingredients, utensils, recipe, satisfaction.)
Idea that there’s this analogy between the way ancient scientists thought and the way everyday people in Democracies think; the former are geniuses and the latter are not, but both their ideas are confined to intuitive thinking in a certain sense. Heavier objects fall faster than light ones.
(Could you look at ancient Athens as a kind of pinnacle of western intuitive thought?… I suppose, though, part of why Plato caused a stir was that his morality is counter-intuitive — Justice is not the will of the stronger, etc.)
