I was reading in bed last night and stumbled across this line. I must have read it 30 times before I put the book down and turned off my light, right in the middle of the chapter. I fell asleep with "cannot surmount the established conclusions amid which it has been reared" ringing in my head.

"In the problems which the Almighty sets his humble servants things hardly ever happen the same way twice over, or if they seem to do so there is some variant which stultifies undue generalisation. The human mind, excet when guided by extraordinary genius, cannot surmount the established conclusions amid which it has been reared."

-----Winston Churchill, from "The Gathering Storm"
