Epicurus' Letter to Herodotus
This letter is devoted to the subject of explaining the natural means by which the earth was formed and the phenomena we see around us occurs, and that all these happen without the participation of any supernatural forces.
It also provides important information about "how to think" - the method by which we examine these issues and how we determine what is true. These basic observations about Evidence and how to weigh it would likely have formed the foundation of the lost work entitled "The Canon of Truth."
This letter forms the necessary preliminary foundation to discussing the issue of things in the sky about which we have limited knowledge (the Letter to Pythocles) and the issue of how men should live given the nature of the universe (the Letter to Menoeceus).
