Keep you away from all that is not born of knowledge and that which can not be proved beyond doubt.
Keep away from all that makes no sense.
Keep away from that which does not demonstrate itself to have honest value.
Keep away from all that which has not reason.
Live by the certainties of knowledge and search for more knowledge, for it shall be your greatest wealth, and will sustain you and your children and your children's children for all time. To do other will condemn you to live in fantasy and ignore your own reality, which shall bring only death onto you in the fullness of time.
From the Hallowed Book of Man
(Extract from The Covenant)
