"Of what school art thou, divine sage?"
"I am a Cynic, lord, because I wear a tattered mantle; I am a Stoic, because I bear poverty patiently; I am a Peripatetic, for, not owning a litter, I go on foot from one wine-shop to another, and on the way teach those who promise to pay for a pitcher of wine."
"And at the pitcher thou dost become a rhetor?"
"Heraclitus declares that 'all is fluid,' and canst thou deny, lord, that wine is fluid?"
(Chapter XIII)
