The principles of meeting facilitation, as delineated three centuries ago.
…a mutual deference is affected; contempt of others disguised; authority concealed; attention given to each in his turn; and an easy stream of conversation maintained, without vehemence, without interruption, without eagerness for victory, and without any airs of superiority. These attentions and regards are immediately agreeable to others, abstracted from any consideration of utility or beneficial tendencies: they conciliate affection, promote esteem, and extremely enhance the merit of the person who regulates his behaviour by them.
–David Hume 1711-1776
