Last Sunday I bought and read "Fragments" by Heraclitus. It is a light book since it has parallel Greek/English text (and I don't read Greek, as much as I would like to). It claims to contain all known fragments that remain of Heraclitus' writings. It's not much. For those who don't know, he's the "you never step in the same river twice" guy who lived in Ephesus around 2500 years ago. He also has some more interesting things to say, such as:
"Tainted souls who try
to purify themselves with blood
are like the man
who steps in filth and thinks
to bathe in sewage."
"Stupidity is better kept a secret than displayed."
"All people ought to know themselves and everyone be wholly mindful."
"Goat cheese melted in warm wine congeals if not well stirred." (2500 year old culinary advice?)
"The cosmos works by harmony of tensions, like the lyre and the bow."
"Silence, healing."
