Language, Mythology and Laws

When i write about julius caesar, when i write about alexander the great, i can, in some imaginative sense, transpose myself into their shoes. I know what it is to be a human being because i have an inside view of them. True, i cannot be certain of what their motives are, but i know what it's like to plan and strive for something. And how do i know these things? Through three great doors which havee always laid open before us - language, mythology and laws.
