ANSWER: As old as humanity. Huna is not unique to Hawaii, although the combination of ideas as a coherent philosophy may be. Here is a quote related to the fifth principle from "Memorabilia of Socrates," by Xenophon, written in the 4th century B.C.:
(Critobulus has asked Socrates how to make a friend) "It is reported," replied Socrates, "that there are some words so powerful that they who know them make themselves loved by pronouncing them." "And where can one learn these words?" added Critobulus. "Have you not read in Homer," answered Socrates, "what the Syrens said to enchant Ulysses? The beginning of it is thus--'Oh stay! Oh pride of Greece, Ulysses, stay!' -- "I begin to understand," said Critobulus, "and seeing this charm, which is so powerful to enchant and captivate the mind, is nothing but praise, you mean that we ought to praise a man in such a manner that he may not distrust we laugh at him, otherwise, instead of gaining his affection, we shall incur his hate."
