Dogma
''Knowledge, particularly the raw knowledge of ideas, is supreme. An idea has no weight, but it can move mountains. The greatest gift of humankind, an idea outweighs anything made by mortal hands. Knowledge is power and must be used with care, but hiding it away from others is never a good thing. Stifle no new ideas, no matter how false and crazed they seem; rather, let them be heard and considered. Never slay a singer, nor stand by as others do so. Spread knowledge wherever it is prudent to do so. Curb and deny falsehoods, rumor, and deceitful tales whenever you encounter them. Write or copy lore of great value at least once a year and give it away. Sponsor and teach bards, scribes, and record keepers. Spread truth and knowledge so that all folk know more. Never deliver a message falsely or incompletely. Teach reading and writing to those who ask (if your time permits), and charge no fee for the teaching.''
