Eons "M" and "H" , and statements of knowledge, thought out philosophy enough. But nearby eon with code " Xi " , transferred to the alphabet of the Greek alphabet , was so misunderstood that it stopped using the letter .

I think that the close proximity of the natural principle of " Samech /xi " principles " Skazyvanie " and "Knowledge " contains a clue to what is knowledge . No doubt that will be found icons and secular images eon . And yet even in wikipedia empty.
Probably will be among the key word " axiom ", " sex ", " Oxford " ...
Oxford - the oldest university town in England , the stronghold of English education .
I do not know to what the concept of " ox " in the name " Oxford " plus " Ford - wade " , I'm surprised Translation " oxford - Shoe " , but any knowledge must be treated as nepolnovodnomu .
