These lines by Lucretius point to the solution:
Our terrors and our darknesses of mind
Must be dispelled, not by the sunshine's rays,
Not by those shining arrows of the light,
But by insight into nature, and a scheme
Of systematic contemplation.
Is there anything else by Lucretius to add to this to be more specific?
I remember now the book "The Demon Haunted World" by Carl Sagan. Wikipedia has a good overview:
So would this be considered a much more clear (and modern) understanding of what Epicurus was beginning to present, by his looking to nature? When we use science correctly, is it a much more complex system compared to Epicurean philosophy? Maybe it might be good to have a table to graphically show similiarities between Epicureanism and modern science.
Also, the "dragon in the garage" story in the above Wikipedia article shows how metaphor can be used to illustrate ideas.
