the same pattern is selective and the pattern applies to different social contexts that
require cognitive perception.

Comment: The essay is based on author's understanding that the Samoa ritual
promotes the idea of hierarchy in the men group power. It is missing the critical

direct analogies had been made by archaic rituals reproduced generation by
generation rather different function and meaning.
