something that cannot be explained cannot be seen - HvF, 1979 - in Froese 2011 p 5

It is interesting to note that something that can-

not be explained – that is, for which we cannot

show a cause or for which do not have a

reason – we do not wish to see. In other words,

something that cannot be explained cannot be

seen. This is driven home again and again by

Don Juan, a Yaqui Indian, Carlos Castaneda’s

mentor. (von Foerster, 1979)
